+# VS Code Automation
+
+Automate VS Code (Code OSS) using agent-browser. VS Code is built on Electron/Chromium and exposes a Chrome DevTools Protocol (CDP) port that agent-browser can connect to, enabling the same snapshot-interact workflow used for web pages.
+
+## Prerequisites
+
+- **`agent-browser` must be installed.** It's listed in devDependencies — run `npm install` in the repo root. Use `npx agent-browser` if it's not on your PATH, or install globally with `npm install -g agent-browser`.
+- **For Code OSS (VS Code dev build):** The repo must be built before launching. `./scripts/code.sh` runs the build automatically if needed, or set `VSCODE_SKIP_PRELAUNCH=1` to skip the compile step if you've already built.
+- **CSS selectors are internal implementation details.** Selectors like `.interactive-input-part`, `.interactive-input-editor`, and `.part.auxiliarybar` used in `eval` commands are VS Code internals that may change across versions. If they stop working, use `agent-browser snapshot -i` to re-discover the current DOM structure.
+
+## Core Workflow
+
+1. **Launch** Code OSS with remote debugging enabled
+2. **Connect** agent-browser to the CDP port
+3. **Snapshot** to discover interactive elements
+4. **Interact** using element refs
+5. **Re-snapshot** after navigation or state changes
+
+> **📸 Take screenshots for a paper trail.** Use `agent-browser screenshot <path>` at key moments — after launch, before/after interactions, and when something goes wrong. Screenshots provide visual proof of what the UI looked like and are invaluable for debugging failures or documenting what was accomplished.
+>
+> Save screenshots inside a timestamped subfolder so each run is isolated and nothing gets overwritten:
+>
+> ```bash
+> # Create a timestamped folder for this run's screenshots
+> SCREENSHOT_DIR="/tmp/code-oss-screenshots/$(date +%Y-%m-%dT%H-%M-%S)"
+> mkdir -p "$SCREENSHOT_DIR"
+>
+> # Save a screenshot (path is a positional argument — use ./ or absolute paths)
+> # Bare filenames without ./ may be misinterpreted as CSS selectors
+> agent-browser screenshot "$SCREENSHOT_DIR/after-launch.png"
+> ```
+
+```bash
+# Launch Code OSS with remote debugging
+./scripts/code.sh --remote-debugging-port=9224
+
+# Wait for Code OSS to start, retry until connected
+for i in 1 2 3 4 5; do agent-browser connect 9224 2>/dev/null && break || sleep 3; done
+
+# Verify you're connected to the right target (not about:blank)
+# If `tab` shows the wrong target, run `agent-browser close` and reconnect
+agent-browser tab
+
+# Discover UI elements
+agent-browser snapshot -i
+
+# Focus the chat input (macOS)
+agent-browser press Control+Meta+i
+```
+
+## Connecting
+
+```bash
+# Connect to a specific port
+agent-browser connect 9222
+
+# Or use --cdp on each command
+agent-browser --cdp 9222 snapshot -i
+
+# Auto-discover a running Chromium-based app
+agent-browser --auto-connect snapshot -i
+```
+
+After `connect`, all subsequent commands target the connected app without needing `--cdp`.
+
+## Tab Management
+
+Electron apps often have multiple windows or webviews. Use tab commands to list and switch between them:
+
+```bash
+# List all available targets (windows, webviews, etc.)
+agent-browser tab
+
+# Switch to a specific tab by index
+agent-browser tab 2
+
+# Switch by URL pattern
+agent-browser tab --url "*settings*"
+```
+
+## Launching Code OSS (VS Code Dev Build)
+
+The VS Code repository includes `scripts/code.sh` which launches Code OSS from source. It passes all arguments through to the Electron binary, so `--remote-debugging-port` works directly:
+
+```bash
+cd <repo-root>  # the root of your VS Code checkout
+./scripts/code.sh --remote-debugging-port=9224
+```
+
+Wait for the window to fully initialize, then connect:
+
+```bash
+# Wait for Code OSS to start, retry until connected
+for i in 1 2 3 4 5; do agent-browser connect 9224 2>/dev/null && break || sleep 3; done
+
+# Verify you're connected to the right target (not about:blank)
+# If `tab` shows the wrong target, run `agent-browser close` and reconnect
+agent-browser tab
+agent-browser snapshot -i
+```
+
+**Tips:**
+- Set `VSCODE_SKIP_PRELAUNCH=1` to skip the compile step if you've already built: `VSCODE_SKIP_PRELAUNCH=1 ./scripts/code.sh --remote-debugging-port=9224` (from the repo root)
+- Code OSS uses the default user data directory. Unlike VS Code Insiders, you don't typically need `--user-data-dir` since there's usually only one Code OSS instance running.
+- If you see "Sent env to running instance. Terminating..." it means Code OSS is already running and forwarded your args to the existing instance. Quit Code OSS and relaunch with the flag, or use `--user-data-dir=/tmp/code-oss-debug` to force a new instance.
+
+## Launching the Agents App (Agents Window)
+
+The Agents app is a separate workbench mode launched with the `--agents` flag. It uses a dedicated user data directory to avoid conflicts with the main Code OSS instance.
+
+```bash
+cd <repo-root>  # the root of your VS Code checkout
+./scripts/code.sh --agents --remote-debugging-port=9224
+```
+
+Wait for the window to fully initialize, then connect:
+
+```bash
+# Wait for Agents app to start, retry until connected
+for i in 1 2 3 4 5; do agent-browser connect 9224 2>/dev/null && break || sleep 3; done
+
+# Verify you're connected to the right target (not about:blank)
+agent-browser tab
+agent-browser snapshot -i
+```
+
+**Tips:**
+- The `--agents` flag launches the Agents workbench instead of the standard VS Code workbench.
+- Set `VSCODE_SKIP_PRELAUNCH=1` to skip the compile step if you've already built.
+
+## Launching VS Code Extensions for Debugging
+
+To debug a VS Code extension via agent-browser, launch VS Code Insiders with `--extensionDevelopmentPath` and `--remote-debugging-port`. Use `--user-data-dir` to avoid conflicting with an already-running instance.
+
+```bash
+# Build the extension first
+cd <extension-repo-root>  # e.g., the root of your extension checkout
+npm run compile
+
+# Launch VS Code Insiders with the extension and CDP
+code-insiders \
+  --extensionDevelopmentPath="<extension-repo-root>" \
+  --remote-debugging-port=9223 \
+  --user-data-dir=/tmp/vscode-ext-debug
+
+# Wait for VS Code to start, retry until connected
+for i in 1 2 3 4 5; do agent-browser connect 9223 2>/dev/null && break || sleep 3; done
+
+# Verify you're connected to the right target (not about:blank)
+# If `tab` shows the wrong target, run `agent-browser close` and reconnect
+agent-browser tab
+agent-browser snapshot -i
+```
+
+**Key flags:**
+- `--extensionDevelopmentPath=<path>` — loads your extension from source (must be compiled first)
+- `--remote-debugging-port=9223` — enables CDP (use 9223 to avoid conflicts with other apps on 9222)
+- `--user-data-dir=<path>` — uses a separate profile so it starts a new process instead of sending to an existing VS Code instance
+
+**Without `--user-data-dir`**, VS Code detects the running instance, forwards the args to it, and exits immediately — you'll see "Sent env to running instance. Terminating..." and CDP never starts.
+
+## Restarting After Code Changes
+
+**After making changes to Code OSS source code, you must restart to pick up the new build.** The workbench loads the compiled JavaScript at startup — changes are not hot-reloaded.
+
+### Restart Workflow
+
+1. **Rebuild** the changed code
+2. **Kill** the running Code OSS instance
+3. **Relaunch** with the same flags
+
+```bash
+# 1. Ensure your build is up to date.
+#    Normally you can skip a manual step here and let ./scripts/code.sh in step 3
+#    trigger the build when needed (or run `npm run watch` in another terminal).
+
+# 2. Kill the Code OSS instance listening on the debug port (if running)
+pids=$(lsof -t -i :9224)
+if [ -n "$pids" ]; then
+	kill $pids
+fi
+
+# 3. Relaunch
+./scripts/code.sh --remote-debugging-port=9224
+
+# 4. Reconnect agent-browser
+for i in 1 2 3 4 5; do agent-browser connect 9224 2>/dev/null && break || sleep 3; done
+agent-browser tab
+agent-browser snapshot -i
+```
+
+> **Tip:** If you're iterating frequently, run `npm run watch` in a separate terminal so compilation happens automatically. You still need to kill and relaunch Code OSS to load the new build.
+
+## Interacting with Monaco Editor (Chat Input, Code Editors)
+
+VS Code uses Monaco Editor for all text inputs including the Copilot Chat input. Monaco editors require specific agent-browser techniques — standard `click`, `fill`, and `keyboard type` commands may not work depending on the VS Code build.
+
+### The Universal Pattern: Focus via Keyboard Shortcut + `press`
+
+This works on **all** VS Code builds (Code OSS, Insiders, stable):
+
+```bash
+# 1. Open and focus the chat input with the keyboard shortcut
+# macOS:
+agent-browser press Control+Meta+i
+# Linux / Windows:
+agent-browser press Control+Alt+i
+
+# 2. Type using individual press commands
+agent-browser press H
+agent-browser press e
+agent-browser press l
+agent-browser press l
+agent-browser press o
+agent-browser press Space  # Use "Space" for spaces
+agent-browser press w
+agent-browser press o
+agent-browser press r
+agent-browser press l
+agent-browser press d
+
+# Verify text appeared (optional)
+agent-browser eval '
+(() => {
+  const sidebar = document.querySelector(".part.auxiliarybar");
+  const viewLines = sidebar.querySelectorAll(".interactive-input-editor .view-line");
+  return Array.from(viewLines).map(vl => vl.textContent).join("|");
+})()'
+
+# 3. Send the message (same on all platforms)
+agent-browser press Enter
+```
+
+**Chat focus shortcut by platform:**
+- **macOS:** `Ctrl+Cmd+I` → `agent-browser press Control+Meta+i`
+- **Linux:** `Ctrl+Alt+I` → `agent-browser press Control+Alt+i`
+- **Windows:** `Ctrl+Alt+I` → `agent-browser press Control+Alt+i`
+
+This shortcut focuses the chat input and sets `document.activeElement` to a `DIV` with class `native-edit-context` — VS Code's native text editing surface that correctly processes key events from `agent-browser press`.
+
+### `type @ref` — Works on Some Builds
+
+On VS Code Insiders (extension debug mode), `type @ref` handles focus and input in one step:
+
+```bash
+agent-browser snapshot -i
+# Look for: textbox "The editor is not accessible..." [ref=e62]
+agent-browser type @e62 "Hello from George!"
+```
+
+> **Tip:** If `type @ref` silently drops text (the editor stays empty), the ref may be stale or the editor not yet ready. Re-snapshot to get a fresh ref and try again. You can verify text was entered using the snippet in "Verifying Text and Clearing" below.
+
+However, **`type @ref` silently fails on Code OSS** — the command completes without error but no text appears. This also applies to `keyboard type` and `keyboard inserttext`. Always verify text appeared after typing, and fall back to the keyboard shortcut + `press` pattern if it didn't. The `press`-per-key approach works universally across all builds.
+
+> **⚠️ Warning:** `keyboard type` can hang indefinitely in some focus states (e.g., after JS mouse events). If it doesn't return within a few seconds, interrupt it and fall back to `press` for individual keystrokes.
+
+### Compatibility Matrix
+
+| Method | VS Code Insiders | Code OSS |
+|--------|-----------------|----------|
+| `press` per key (after focus shortcut) | ✅ Works | ✅ Works |
+| `type @ref` | ✅ Works | ❌ Silent fail |
+| `keyboard type` (after focus) | ✅ Works | ❌ Silent fail |
+| `keyboard inserttext` (after focus) | ✅ Works | ❌ Silent fail |
+| `click @ref` | ❌ Blocked by overlay | ❌ Blocked by overlay |
+| `fill @ref` | ❌ Element not visible | ❌ Element not visible |
+
+### Fallback: Focus via JavaScript Mouse Events
+
+If the keyboard shortcut doesn't work (e.g., chat panel isn't configured), you can focus the editor via JavaScript:
+
+```bash
+agent-browser eval '
+(() => {
+  const inputPart = document.querySelector(".interactive-input-part");
+  const editor = inputPart.querySelector(".monaco-editor");
+  const rect = editor.getBoundingClientRect();
+  const x = rect.x + rect.width / 2;
+  const y = rect.y + rect.height / 2;
+  editor.dispatchEvent(new MouseEvent("mousedown", { bubbles: true, clientX: x, clientY: y }));
+  editor.dispatchEvent(new MouseEvent("mouseup", { bubbles: true, clientX: x, clientY: y }));
+  editor.dispatchEvent(new MouseEvent("click", { bubbles: true, clientX: x, clientY: y }));
+  return "activeElement: " + document.activeElement?.className;
+})()'
+
+# Then use press for each character
+agent-browser press H
+agent-browser press e
+# ...
+```
+
+### Verifying Text and Clearing
+
+```bash
+# Verify text in the chat input
+agent-browser eval '
+(() => {
+  const sidebar = document.querySelector(".part.auxiliarybar");
+  const viewLines = sidebar.querySelectorAll(".interactive-input-editor .view-line");
+  return Array.from(viewLines).map(vl => vl.textContent).join("|");
+})()'
+
+# Clear the input (Select All + Backspace)
+# macOS:
+agent-browser press Meta+a
+# Linux / Windows:
+agent-browser press Control+a
+# Then delete:
+agent-browser press Backspace
+```
+
+### Screenshot Tips for VS Code
+
+On ultrawide monitors, the chat sidebar may be in the far-right corner of the CDP screenshot. Options:
+- Use `agent-browser screenshot --full` to capture the entire window
+- Use element screenshots: `agent-browser screenshot ".part.auxiliarybar" sidebar.png`
+- Use `agent-browser screenshot --annotate` to see labeled element positions
+- Maximize the sidebar first: click the "Maximize Secondary Side Bar" button
+
+> **macOS:** If `agent-browser screenshot` returns "Permission denied", your terminal needs Screen Recording permission. Grant it in **System Settings → Privacy & Security → Screen Recording**. As a fallback, use the `eval` verification snippet to confirm text was entered — this doesn't require screen permissions.
+
+## Troubleshooting
+
+### "Connection refused" or "Cannot connect"
+
+- Make sure Code OSS was launched with `--remote-debugging-port=NNNN`
+- If Code OSS was already running, quit and relaunch with the flag
+- Check that the port isn't in use by another process:
+  - macOS / Linux: `lsof -i :9224`
+  - Windows: `netstat -ano | findstr 9224`
+
+### Elements not appearing in snapshot
+
+- VS Code uses multiple webviews. Use `agent-browser tab` to list targets and switch to the right one
+- Use `agent-browser snapshot -i -C` to include cursor-interactive elements (divs with onclick handlers)
+
+### Cannot type in Monaco Editor inputs
+
+- Use `agent-browser press` for individual keystrokes after focusing the input. Focus the chat input with the keyboard shortcut (macOS: `Ctrl+Cmd+I`, Linux/Windows: `Ctrl+Alt+I`).
+- `type @ref`, `keyboard type`, and `keyboard inserttext` work on VS Code Insiders but **silently fail on Code OSS** — they complete without error but no text appears. The `press`-per-key approach works universally.
+- See the "Interacting with Monaco Editor" section above for the full compatibility matrix.
+
+## Cleanup
+
+**Always kill the Code OSS instance when you're done.** Code OSS is a full Electron app that consumes significant memory (often 1–4 GB+). Leaving it running wastes resources and holds the CDP port.
+
+```bash
+# Disconnect agent-browser
+agent-browser close
+
+# Kill the Code OSS instance listening on the debug port (if running)
+# macOS / Linux:
+pids=$(lsof -t -i :9224)
+if [ -n "$pids" ]; then
+	kill $pids
+fi
+
+# Windows:
+# taskkill /F /PID <PID>
+# Or use Task Manager to end "Code - OSS"
+```
+
+Verify it's gone:
+```bash
+# Confirm no process is listening on the debug port
+lsof -i :9224  # should return nothing
+```

+name: Agents Window Developer
+description: Specialist in developing the Agents Window
+---
+
+# Role and Objective
+
+You are a developer working on the 'agents window'. Your goal is to make changes to the agents window (`src/vs/sessions`), minimally editing outside of that directory.
+
+# Instructions
+
+1.  **Always read the `sessions` skill first.** This is your primary source of truth for the sessions architecture.
+    -   Invoke `skill: "sessions"`.
+2.  Focus your work on `src/vs/sessions/`.
+3.  Avoid making changes to core VS Code files (`src/vs/workbench/`, `src/vs/platform/`, etc.) unless absolutely necessary for the agents window functionality.

+applyTo: 'src/vs/platform/agentHost/**'
+---
+
+# Agent Host
+
+The agent host communicates via the Agent Host Protocol. The specification for this lives in a directory `../agent-host-protocol` as a sibling of the VS Code directory.
+
+If this directory doesn't exist, you should use the "ask questions" tool to ask the user if they want to clone `git@github.com:microsoft/agent-host-protocol.git` to that directory. After doing so, you should also prompt the user to add `file:///<path/to/agent-host-protocol>/plugins/copilot-plugin` as a plugin in their `chat.pluginLocations` settings.
+
+## Overall Protocol
+
+The sessions process is a portable, standalone server that multiple clients can connect to. Clients see a synchronized view of sessions and can send commands that are reflected back as state-changing actions. The protocol is designed around four requirements:
+
+1. **Synchronized multi-client state** — an immutable, redux-like state tree mutated exclusively by actions flowing through pure reducers. While there is the option to implement functionality via imperative commands, we ALWAYS prefer to model features as pure state and actions.
+2. **Lazy loading** — clients subscribe to state by URI and load data on demand. The session list is fetched imperatively. Large content (images, long tool outputs) is stored by reference and fetched separately.
+3. **Write-ahead with reconciliation** — clients optimistically apply their own actions locally, then reconcile when the server echoes them back alongside any concurrent actions from other clients or the server itself.
+4. **Forward-compatible versioning** — newer clients can connect to older servers. A single protocol version number maps to a capabilities object; clients check capabilities before using features.
+
+See the agent host protocol documentation for more details.
+
+## End to End Testing
+
+You can run `node ./scripts/code-agent-host.js` to start an agent host. If you pass `--enable-mock-agent`, then the `ScriptedMockAgent` will be used.
+
+By default this will listen on `ws://127.0.0.1:8081`. You can then use the `ahp-websocket` client, when available, to connect to and communicate with it.

 Follow the `fix-errors` skill guidelines to fix this error. Key principles:
 
-1. **Do NOT fix at the crash site.** Do not add guards, try/catch, or fallback values at the bottom of the stack trace. That only masks the problem.
-2. **Trace the data flow upward** through the call stack to find the producer of invalid data.
-3. **If the producer is cross-process** (e.g., IPC) and cannot be identified from the stack alone, **enrich the error message** with diagnostic context (data type, truncated value, operation name) so the next telemetry cycle reveals the source. Do NOT silently swallow the error.
-4. **If the producer is identifiable**, fix it directly.
+1. **Read the error construction code first.** Before proposing any fix, search the codebase for where the error is constructed (the `new Error(...)` or custom error class instantiation). Read the surrounding code to understand:
+   - What conditions trigger the error (thresholds, validation checks, categorization logic)
+   - What parameters, classifications, or categories the error encodes
+   - What the intended meaning of each category is and what action each warrants
+   - Whether the error is a symptom of invalid data, a threshold-based warning, or a design-time signal
+   Use this understanding to determine the correct fix strategy. Do NOT assume what the error means from its message alone — the construction code is the source of truth.

+5. **If the producer is identifiable**, fix it directly.
 
 After making changes, check for compilation errors via the build task and run relevant unit tests.
+
+## Submitting the Fix
+
+After the fix is validated (compilation clean, tests pass):
+
+1. **Create a branch**: `git checkout -b <github-username>/<short-description>` (e.g., `bryanchen-d/fix-notebook-index-error`).
+2. **Commit**: Stage changed files and commit with a message like `fix: <brief description> (#<issue-number>)`.
+3. **Push**: `git push -u origin <branch-name>`.
+4. **Create a draft PR** with a description that includes these sections:
+   - **Summary**: A concise description of what was changed and why.
+   - **Issue link**: `Fixes #<issue-number>` so GitHub auto-closes the issue when the PR merges.
+   - **Trigger scenarios**: What user actions or system conditions cause this error to surface.
+   - **Code flow diagram**: A Mermaid swimlane/sequence diagram showing the call chain from trigger to error. Use participant labels for the key components (e.g., classes, modules, processes). Example:
+     ````
+     ```mermaid
+     sequenceDiagram
+         participant A as CallerComponent
+         participant B as MiddleLayer
+         participant C as LowLevelUtil
+         A->>B: someOperation(data)
+         B->>C: validate(data)
+         C-->>C: data is invalid
+         C->>B: throws "error message"
+         B->>A: unhandled error propagates
+     ```
+     ````
+   - **Manual validation steps**: Concrete, step-by-step instructions a reviewer can follow to reproduce the original error and verify the fix. Include specific setup requirements (e.g., file types to open, settings to change, actions to perform). If the error cannot be easily reproduced manually, explain why and describe what alternative validation was performed (e.g., unit tests, code inspection).
+   - **How the fix works**: A brief explanation of the fix approach, with a note per changed file.
+5. **Monitor the PR — BLOCKING**: You MUST NOT complete the task until the monitoring loop below is done.
+   - Wait 2 minutes after each push, then check for Copilot review comments using `gh pr view <number> --json reviews,comments` and `gh api repos/{owner}/{repo}/pulls/{number}/comments`.
+   - If there are review comments, evaluate each one:
+     - If valid, apply the fix in a new commit, push, and **resolve the comment thread** using the GitHub GraphQL API (`resolveReviewThread` mutation with the thread's node ID).
+     - If not applicable, leave a reply explaining why.
+     - After addressing comments, update the PR description if the changes affect the summary, diagram, or per-file notes.
+   - **Re-run tests** after addressing review comments to confirm nothing regressed.
+   - After each push, repeat the wait-and-check cycle. Continue until **two consecutive checks return zero new comments**.
+6. **Verify CI**: After the monitoring loop is done, check that CI checks are passing using `gh pr checks <number>`. If any required checks fail, investigate and fix. Do NOT complete the task with failing CI.

+description: Use when adding, modifying, or reviewing VS Code configuration policies. Covers the full policy lifecycle from registration to export to platform-specific artifacts. Run on ANY change that adds a `policy:` field to a configuration property.
+---
+
+# Adding a Configuration Policy
+
+Policies allow enterprise administrators to lock configuration settings via OS-level mechanisms (Windows Group Policy, macOS managed preferences, Linux config files) or via Copilot account-level policy data. This skill covers the complete procedure.
+
+## When to Use
+
+- Adding a new `policy:` field to any configuration property
+- Modifying an existing policy (rename, category change, etc.)
+- Reviewing a PR that touches policy registration
+- Adding account-based policy support via `IPolicyData`
+
+## Architecture Overview
+
+### Policy Sources (layered, last writer wins)
+
+| Source | Implementation | How it reads policies |
+|--------|---------------|----------------------|
+| **OS-level** (Windows registry, macOS plist) | `NativePolicyService` via `@vscode/policy-watcher` | Watches `Software\Policies\Microsoft\{productName}` (Windows) or bundle identifier prefs (macOS) |
+| **Linux file** | `FilePolicyService` | Reads `/etc/vscode/policy.json` |
+| **Account/GitHub** | `AccountPolicyService` | Reads `IPolicyData` from `IDefaultAccountService.policyData`, applies `value()` function |
+| **Multiplex** | `MultiplexPolicyService` | Combines OS-level + account policy services; used in desktop main |
+
+### Key Files
+
+| File | Purpose |
+|------|---------|
+| `src/vs/base/common/policy.ts` | `PolicyCategory` enum, `IPolicy` interface |
+| `src/vs/platform/policy/common/policy.ts` | `IPolicyService`, `AbstractPolicyService`, `PolicyDefinition` |
+| `src/vs/platform/configuration/common/configurations.ts` | `PolicyConfiguration` — bridges policies to configuration values |
+| `src/vs/workbench/services/policies/common/accountPolicyService.ts` | Account/GitHub-based policy evaluation |
+| `src/vs/workbench/services/policies/common/multiplexPolicyService.ts` | Combines multiple policy services |
+| `src/vs/workbench/contrib/policyExport/electron-browser/policyExport.contribution.ts` | `--export-policy-data` CLI handler |
+| `src/vs/base/common/defaultAccount.ts` | `IPolicyData` interface for account-level policy fields |
+| `build/lib/policies/policyData.jsonc` | Auto-generated policy catalog (DO NOT edit manually) |
+| `build/lib/policies/policyGenerator.ts` | Generates ADMX/ADML (Windows), plist (macOS), JSON (Linux) |
+| `build/lib/test/policyConversion.test.ts` | Tests for policy artifact generation |
+
+## Procedure
+
+### Step 1 — Add the `policy` field to the configuration property
+
+Find the configuration registration (typically in a `*.contribution.ts` file) and add a `policy` object to the property schema.
+
+**Required fields:**
+
+**Determining `minimumVersion`:** Always read `version` from the root `package.json` and use the `major.minor` portion. For example, if `package.json` has `"version": "1.112.0"`, use `minimumVersion: '1.112'`. Never hardcode an old version like `'1.99'`.
+
+```typescript
+policy: {
+    name: 'MyPolicyName',                          // PascalCase, unique across all policies
+    category: PolicyCategory.InteractiveSession,    // From PolicyCategory enum
+    minimumVersion: '1.112',                        // Use major.minor from package.json version
+    localization: {
+        description: {
+            key: 'my.config.key',                   // NLS key for the description
+            value: nls.localize('my.config.key', "Human-readable description."),
+        }
+    }
+}
+```
+
+**Optional: `value` function for account-based policy:**
+
+If this policy should also be controllable via Copilot account policy data (from `IPolicyData`), add a `value` function:
+
+```typescript
+policy: {
+    name: 'MyPolicyName',
+    category: PolicyCategory.InteractiveSession,
+    minimumVersion: '1.112',                        // Use major.minor from package.json version
+    value: (policyData) => policyData.my_field === false ? false : undefined,
+    localization: { /* ... */ }
+}
+```
+
+The `value` function receives `IPolicyData` (from `src/vs/base/common/defaultAccount.ts`) and should:
+- Return a concrete value to **override** the user's setting
+- Return `undefined` to **not apply** any account-level override (falls through to OS policy or user setting)
+
+If you need a new field on `IPolicyData`, add it to the interface in `src/vs/base/common/defaultAccount.ts`.
+
+**Optional: `enumDescriptions` for enum/string policies:**
+
+```typescript
+localization: {
+    description: { key: '...', value: nls.localize('...', "...") },
+    enumDescriptions: [
+        { key: 'opt.none', value: nls.localize('opt.none', "No access.") },
+        { key: 'opt.all', value: nls.localize('opt.all', "Full access.") },
+    ]
+}
+```
+
+### Step 2 — Ensure `PolicyCategory` is imported
+
+```typescript
+import { PolicyCategory } from '../../../../base/common/policy.js';
+```
+
+Existing categories in the `PolicyCategory` enum:
+- `Extensions`
+- `IntegratedTerminal`
+- `InteractiveSession` (used for all chat/Copilot policies)
+- `Telemetry`
+- `Update`
+
+If you need a new category, add it to `PolicyCategory` in `src/vs/base/common/policy.ts` and add corresponding `PolicyCategoryData` localization.
+
+### Step 3 — Validate TypeScript compilation
+
+Check the `VS Code - Build` watch task output, or run:
+
+```bash
+npm run compile-check-ts-native
+```
+
+### Step 4 — Export the policy data
+
+Regenerate the auto-generated policy catalog:
+
+```bash
+npm run export-policy-data
+```
+
+This script handles transpilation, sets up `GITHUB_TOKEN` (via `gh` CLI or GitHub OAuth device flow), and runs `--export-policy-data`. The export command reads extension configuration policies from the distro's `product.json` via the GitHub API and merges them into the output.
+
+This updates `build/lib/policies/policyData.jsonc`. **Never edit this file manually.** Verify your new policy appears in the output.  You will need code review from a codeowner to merge the change to main.
+
+
+## Policy for extension-provided settings
+
+Extension authors cannot add `policy:` fields directly—their settings are defined in the extension's `package.json`, not in VS Code core. Instead, policies for extension settings are defined in `vscode-distro`'s `product.json` under the `extensionConfigurationPolicy` key.
+
+### How it works
+
+1. **Source of truth**: The `extensionConfigurationPolicy` map lives in `vscode-distro` under `mixin/{quality}/product.json` (stable, insider, exploration).
+2. **Runtime**: When VS Code starts with a distro-mixed `product.json`, `configurationExtensionPoint.ts` reads `extensionConfigurationPolicy` and attaches matching `policy` objects to extension-contributed configuration properties.
+3. **Export/build**: The `--export-policy-data` command fetches the distro's `product.json` at the commit pinned in `package.json` and merges extension policies into the output. Use `npm run export-policy-data` which sets up authentication automatically.
+
+### Distro format
+
+Each entry in `extensionConfigurationPolicy` must include:
+
+```json
+"extensionConfigurationPolicy": {
+    "publisher.extension.settingName": {
+        "name": "PolicyName",
+        "category": "InteractiveSession",
+        "minimumVersion": "1.99",
+        "description": "Human-readable description."
+    }
+}
+```
+
+- `name`: PascalCase policy name, unique across all policies
+- `category`: Must be a valid `PolicyCategory` enum value (e.g., `InteractiveSession`, `Extensions`)
+- `minimumVersion`: The VS Code version that first shipped this policy
+- `description`: Human-readable description string used to generate localization key/value pairs for ADMX/ADML/macOS/Linux policy artifacts
+
+### Adding a new extension policy
+
+1. Add the entry to `extensionConfigurationPolicy` in **all three** quality `product.json` files in `vscode-distro` (`mixin/stable/`, `mixin/insider/`, `mixin/exploration/`)
+2. Update the `distro` commit hash in `package.json` to point to the distro commit that includes your new entry — the export command fetches extension policies from the pinned distro commit
+3. Regenerate `policyData.jsonc` by running `npm run export-policy-data` (see Step 4 above)
+4. Update the test fixture at `src/vs/workbench/contrib/policyExport/test/node/extensionPolicyFixture.json` with the new entry
+
+### Test fixtures
+
+The file `src/vs/workbench/contrib/policyExport/test/node/extensionPolicyFixture.json` is a test fixture that must stay in sync with the extension policies in the checked-in `policyData.jsonc`. When extension policies are added or changed in the distro, this fixture must be updated to match — otherwise the integration test will fail because the test output (generated from the fixture) won't match the checked-in file (generated from the real distro).
+
+### Downstream consumers
+
+| Consumer | What it reads | Output |
+|----------|--------------|--------|
+| `policyGenerator.ts` | `policyData.jsonc` | ADMX/ADML (Windows GP), `.mobileconfig` (macOS), `policy.json` (Linux) |

+## Testing Pipeline Changes
+
+When the user asks to **test changes in an Azure Pipelines build**, follow this workflow:
+
+1. **Queue a new build** on the current branch
+2. **Poll for completion** by periodically checking the build status until it finishes
+
+### Polling for Build Completion
+
+Use a shell loop with `sleep` to poll the build status. The `sleep` command works on all major operating systems:
+
+```bash
+# Queue the build and note the build ID from output (e.g., 123456)
+node .github/skills/azure-pipelines/azure-pipeline.ts queue
+
+# Poll every 60 seconds until complete (works on macOS, Linux, and Windows with Git Bash/WSL)
+# Replace <BUILD_ID> with the actual build ID from the queue command
+while true; do
+  node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID> --json 2>/dev/null | grep -q '"status": "completed"' && break
+  sleep 60
+done
+
+# Check final result
+node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID>
+```
+
+Alternatively, use the built-in `--watch` flag which handles polling automatically:
+
+```bash
+node .github/skills/azure-pipelines/azure-pipeline.ts queue
+# Use the build ID returned by the queue command
+node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID> --watch
+```
+
+> **Note**: The `--watch` flag polls every 30 seconds by default. Use `--watch 60` for a 60-second interval to reduce API calls.

+description: Use when working on the Chat Customizations editor — the management UI for agents, skills, instructions, hooks, prompts, MCP servers, and plugins.
+---
+
+# Chat Customizations Editor
+
+Split-view management pane for AI customization items across workspace, user, extension, and plugin storage. Supports harness-based filtering (Local, Copilot CLI, Claude).
+
+## Spec
+
+**`src/vs/sessions/AI_CUSTOMIZATIONS.md`** — always read before making changes, always update after.
+
+## Key Folders
+
+| Folder | What |
+|--------|------|
+| `src/vs/workbench/contrib/chat/common/` | `ICustomizationHarnessService`, `ISectionOverride`, `IStorageSourceFilter` — shared interfaces and filter helpers |
+| `src/vs/workbench/contrib/chat/browser/aiCustomization/` | Management editor, list widgets (prompts, MCP, plugins), harness service registration |
+| `src/vs/sessions/contrib/chat/browser/` | Sessions-window overrides (harness service, workspace service) |
+| `src/vs/sessions/contrib/sessions/browser/` | Sessions tree view counts and toolbar |
+
+When changing harness descriptor interfaces or factory functions, verify both core and sessions registrations compile.
+
+## Key Interfaces
+
+- **`IHarnessDescriptor`** — drives all UI behavior declaratively (hidden sections, button overrides, file filters, agent gating). See spec for full field reference.
+- **`ISectionOverride`** — per-section button customization (command invocation, root file creation, type labels, file extensions).
+- **`IStorageSourceFilter`** — controls which storage sources and user roots are visible per harness/type.
+- **`IExternalCustomizationItemProvider`** / **`IExternalCustomizationItem`** — internal interfaces (in `customizationHarnessService.ts`) for extension-contributed providers that supply items directly. These mirror the proposed extension API types.
+
+Principle: the UI widgets read everything from the descriptor — no harness-specific conditionals in widget code.
+
+## Extension API (`chatSessionCustomizationProvider`)
+
+The proposed API in `src/vscode-dts/vscode.proposed.chatSessionCustomizationProvider.d.ts` lets extensions register customization providers. Changes to `IExternalCustomizationItem` or `IExternalCustomizationItemProvider` must be kept in sync across the full chain:
+
+| Layer | File | Type |
+|-------|------|------|
+| Extension API | `vscode.proposed.chatSessionCustomizationProvider.d.ts` | `ChatSessionCustomizationItem` |
+| IPC DTO | `extHost.protocol.ts` | `IChatSessionCustomizationItemDto` |
+| ExtHost mapping | `extHostChatAgents2.ts` | `$provideChatSessionCustomizations()` |
+| MainThread mapping | `mainThreadChatAgents2.ts` | `provideChatSessionCustomizations` callback |
+| Internal interface | `customizationHarnessService.ts` | `IExternalCustomizationItem` |
+
+When adding fields to `IExternalCustomizationItem`, update all five layers. The proposed API `.d.ts` is additive-only (new optional fields are backward-compatible and do not require a version bump).
+
+## Testing
+
+Component explorer fixtures (see `component-fixtures` skill): `aiCustomizationListWidget.fixture.ts`, `aiCustomizationManagementEditor.fixture.ts` under `src/vs/workbench/test/browser/componentFixtures/`.
+
+### Screenshotting specific tabs
+
+The management editor fixture supports a `selectedSection` option to render any tab. Each tab has Dark/Light variants auto-generated by `defineThemedFixtureGroup`.
+
+**Available fixture IDs** (use with `mcp_component-exp_screenshot`):
+
+| Fixture ID pattern | Tab shown |
+|---|---|
+| `chat/aiCustomizations/aiCustomizationManagementEditor/AgentsTab/{Dark,Light}` | Agents |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/SkillsTab/{Dark,Light}` | Skills |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/InstructionsTab/{Dark,Light}` | Instructions |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/HooksTab/{Dark,Light}` | Hooks |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/PromptsTab/{Dark,Light}` | Prompts |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/McpServersTab/{Dark,Light}` | MCP Servers |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/PluginsTab/{Dark,Light}` | Plugins |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/LocalHarness/{Dark,Light}` | Default (Agents, Local harness) |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/CliHarness/{Dark,Light}` | Default (Agents, CLI harness) |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/ClaudeHarness/{Dark,Light}` | Default (Agents, Claude harness) |
+| `chat/aiCustomizations/aiCustomizationManagementEditor/Sessions/{Dark,Light}` | Sessions window variant |
+
+**Adding a new tab fixture:** Add a variant to the `defineThemedFixtureGroup` in `aiCustomizationManagementEditor.fixture.ts`:
+```typescript
+MyNewTab: defineComponentFixture({
+    labels: { kind: 'screenshot' },
+    render: ctx => renderEditor(ctx, {
+        harness: CustomizationHarness.VSCode,
+        selectedSection: AICustomizationManagementSection.MySection,
+    }),
+}),
+```
+
+The `selectedSection` calls `editor.selectSectionById()` after `setInput`, which navigates to the specified tab and re-layouts.
+
+### Populating test data
+
+Each customization type requires its own mock path in `createMockPromptsService`:
+- **Agents** — `getCustomAgents()` returns agent objects
+- **Skills** — `findAgentSkills()` returns `IAgentSkill[]`
+- **Prompts** — `getPromptSlashCommands()` returns `IChatPromptSlashCommand[]`
+- **Instructions/Hooks** — `listPromptFiles()` filtered by `PromptsType`
+- **MCP Servers** — `mcpWorkspaceServers`/`mcpUserServers` arrays passed to `IMcpWorkbenchService` mock
+- **Plugins** — `IPluginMarketplaceService.installedPlugins` and `IAgentPluginService.plugins` observables
+
+All test data lives in `allFiles` (prompt-based items) and the `mcpWorkspace/UserServers` arrays. Add enough items per category (8+) to invoke scrolling.
+
+### Exercising built-in grouping
+
+The list widget regroups items from the default chat extension under a "Built-in" header. Three things must be in place for fixtures to exercise this:
+1. Include `BUILTIN_STORAGE` in the harness descriptor's visible sources
+2. Mock `IProductService.defaultChatAgent.chatExtensionId` (e.g., `'GitHub.copilot-chat'`)
+3. Give mock items extension provenance via `extensionId` / `extensionDisplayName` matching that ID
+
+Without all three, built-in regrouping silently doesn't run and the fixture only shows flat lists.
+
+### Editor contribution service mocks
+
+The management editor embeds a `CodeEditorWidget`. Electron-side editor contributions (e.g., `AgentFeedbackEditorWidgetContribution`) are instantiated automatically and crash if their injected services aren't registered. The fixture must mock at minimum:
+- `IAgentFeedbackService` — needs `onDidChangeFeedback`, `onDidChangeNavigation` as `Event.None`
+- `ICodeReviewService` — needs `getReviewState()` / `getPRReviewState()` returning idle observables
+- `IChatEditingService` — needs `editingSessionsObs` as empty observable
+- `IAgentSessionsService` — needs `model.sessions` as empty array
+
+These are cross-layer imports from `vs/sessions/` — use `// eslint-disable-next-line local/code-import-patterns` on the import lines.
+
+### CI regression gates
+
+Key fixtures have `blocksCi: true` in their labels. The `screenshot-test.yml` GitHub Action captures screenshots on every PR to `main` and **fails the CI status check** if any `blocks-ci`-labeled fixture's screenshot changes. This catches layout regressions automatically.
+
+Currently gated fixtures: `LocalHarness`, `McpServersTab`, `McpServersTabNarrow`, `AgentsTabNarrow`. When adding a new section or layout-critical fixture, add `blocksCi: true`:
+
+```typescript
+MyFixture: defineComponentFixture({
+    labels: { kind: 'screenshot', blocksCi: true },
+    render: ctx => renderEditor(ctx, { ... }),
+}),
+```
+
+Don't add `blocksCi` to every fixture — only ones that cover critical layout paths (default view, section with list + footer, narrow viewport). Too many gated fixtures creates noisy CI.
+
+### Screenshot stability
+
+Scrollbar fade transitions cause screenshot instability — the scrollbar shifts from `visible` to `invisible fade` class ~2 seconds after a programmatic scroll. After calling `revealLastItem()` or any scroll action, wait for the transition to complete before the fixture's render promise resolves:
+
+```typescript
+await new Promise(resolve => setTimeout(resolve, 2400));
+// Then optionally poll until .scrollbar.vertical loses the 'visible' class
+```
+
+### Running unit tests
+
+```bash
+./scripts/test.sh --grep "applyStorageSourceFilter|customizationCounts"
+npm run compile-check-ts-native && npm run valid-layers-check
+```
+
+See the `sessions` skill for sessions-window specific guidance.
+
+## Debugging Layout in the Real Product
+
+Component fixtures use mock data and a fixed container size. Layout bugs caused by reflow timing, real data shapes, or narrow window sizes often **don't reproduce in fixtures**. When a user reports a broken layout, debug in the live Code OSS product.
+
+For launching Code OSS with CDP and connecting `agent-browser`, see the **`launch` skill**. Use `--user-data-dir /tmp/code-oss-debug` to avoid colliding with an already-running instance from another worktree.
+
+### Navigating to the customizations editor
+
+After connecting, use `snapshot -i` to find the "Open Customizations" button (in the Chat panel header), then click it. To switch sections, use `eval` with a DOM click since sidebar items aren't interactive refs:
+
+```bash
+npx agent-browser eval "const items = [...document.querySelectorAll('.section-list-item')]; \
+  items.find(el => el.textContent?.includes('MCP'))?.click();"
+```
+
+### Inspecting widget layout
+
+`agent-browser eval` doesn't always print return values. Use `document.title` as a return channel:
+
+```bash
+npx agent-browser eval "const w = document.querySelector('.mcp-list-widget'); \
+  const lc = w?.querySelector('.mcp-list-container'); \
+  const rows = lc?.querySelectorAll('.monaco-list-row'); \
+  document.title = 'DBG:rows=' + (rows?.length ?? -1) \
+    + ',listH=' + (lc?.offsetHeight ?? -1) \
+    + ',seStH=' + (lc?.querySelector('.monaco-scrollable-element')?.style?.height ?? '') \
+    + ',wH=' + (w?.offsetHeight ?? -1);"
+npx agent-browser eval "document.title" 2>&1
+```
+
+Key diagnostics:
+- **`rows`** — fewer than expected means `list.layout()` never received the correct viewport height.
+- **`seStH`** — empty means the list was never properly laid out.
+- **`listH` vs `wH`** — list container height should be widget height minus search bar minus footer.
+
+### Common layout issues
+
+| Symptom | Root cause | Fix pattern |
+|---------|-----------|-------------|
+| List shows 0-1 rows in a tall container | `layout()` bailed out because `offsetHeight` returned 0 during `display:none → visible` transition | Defer layout via `DOM.getWindow(this.element).requestAnimationFrame(...)` |
+| Badge or row content clips at right edge | Widget container missing `overflow: hidden` | Add `overflow: hidden` to the widget's CSS class |
+| Items visible in fixture but not in product | Fixture uses many mock items; real product has few | Add fixture variants with fewer items or narrower dimensions (`width`/`height` options) |
+
+### Fixture vs real product gaps
+
+Fixtures render at a fixed size (default 900×600) with many mock items. They won't catch:
+- **Reflow timing** — the real product's `display:none → visible` transition may not have reflowed before `layout()` fires
+- **Narrow windows** — add narrow fixture variants (e.g., `width: 550, height: 400`)
+- **Real data counts** — a user with 1 MCP server sees very different layout than a fixture with 12

+name: component-fixtures
+description: Use when creating or updating component fixtures for screenshot testing, or when designing UI components to be fixture-friendly. Covers fixture file structure, theming, service setup, CSS scoping, async rendering, and common pitfalls.
+---
+
+# Component Fixtures
+
+Component fixtures render isolated UI components for visual screenshot testing via the component explorer. Fixtures live in `src/vs/workbench/test/browser/componentFixtures/` and are auto-discovered by the Vite dev server using the glob `src/**/*.fixture.ts`.
+
+Use tools `mcp_component-exp_`* to list and screenshot fixtures. If you cannot see these tools, inform the user to them on.
+
+## Running Fixtures Locally
+
+1. Start the component explorer server: run the **Component Explorer Server** task
+2. Use the `mcp_component-exp_list_fixtures` tool to see all available fixtures and their URLs
+3. Use the `mcp_component-exp_screenshot` tool to capture screenshots programmatically
+
+## File Structure
+
+Each fixture file exports a default `defineThemedFixtureGroup(...)`. The file must end with `.fixture.ts`.
+
+```
+src/vs/workbench/test/browser/componentFixtures/
+  fixtureUtils.ts              # Shared helpers (DO NOT import @vscode/component-explorer elsewhere)
+  myComponent.fixture.ts       # Your fixture file
+```
+
+## Basic Pattern
+
+```typescript
+import { ComponentFixtureContext, createEditorServices, defineComponentFixture, defineThemedFixtureGroup } from './fixtureUtils.js';
+
+export default defineThemedFixtureGroup({ path: 'myFeature/' }, {
+    Default: defineComponentFixture({ render: renderMyComponent }),
+    AnotherVariant: defineComponentFixture({ render: renderMyComponent }),
+});
+
+function renderMyComponent({ container, disposableStore, theme }: ComponentFixtureContext): void {
+    container.style.width = '400px';
+
+    const instantiationService = createEditorServices(disposableStore, {
+        colorTheme: theme,
+        additionalServices: (reg) => {
+            // Register additional services the component needs
+            reg.define(IMyService, MyServiceImpl);
+            reg.defineInstance(IMockService, mockInstance);
+        },
+    });
+
+    const widget = disposableStore.add(
+        instantiationService.createInstance(MyWidget, /* constructor args */)
+    );
+    container.appendChild(widget.domNode);
+}
+```
+
+Key points:
+- **`defineThemedFixtureGroup`** automatically creates Dark and Light variants for each fixture
+- **`defineComponentFixture`** wraps your render function with theme setup and shadow DOM isolation
+- **`createEditorServices`** provides a `TestInstantiationService` with base editor services pre-registered
+- Always register created widgets with `disposableStore.add(...)` to prevent leaks
+- Pass `colorTheme: theme` to `createEditorServices` so theme colors render correctly
+
+## Utilities from fixtureUtils.ts
+
+| Export | Purpose |
+|---|---|
+| `defineComponentFixture` | Creates Dark/Light themed fixture variants from a render function |
+| `defineThemedFixtureGroup` | Groups multiple themed fixtures into a named fixture group |
+| `createEditorServices` | Creates `TestInstantiationService` with all base editor services |
+| `registerWorkbenchServices` | Registers additional workbench services (context menu, label, etc.) |
+| `createTextModel` | Creates a text model via `ModelService` for editor fixtures |
+| `setupTheme` | Applies theme CSS to a container (called automatically by `defineComponentFixture`) |
+| `darkTheme` / `lightTheme` | Pre-loaded `ColorThemeData` instances |
+
+**Important:** Only `fixtureUtils.ts` may import from `@vscode/component-explorer`. All fixture files must go through the helpers in `fixtureUtils.ts`.
+
+## CSS Scoping
+
+Fixtures render inside shadow DOM. The component-explorer automatically adopts the global VS Code stylesheets and theme CSS.
+
+### Matching production CSS selectors
+
+Many VS Code components have CSS rules scoped to deep ancestor selectors (e.g., `.interactive-session .interactive-input-part > .widget-container .my-element`). In fixtures, you must recreate the required ancestor DOM structure for these selectors to match:
+
+```typescript
+function render({ container }: ComponentFixtureContext): void {
+    container.classList.add('interactive-session');
+
+    // Recreate ancestor structure that CSS selectors expect
+    const inputPart = dom.$('.interactive-input-part');
+    const widgetContainer = dom.$('.widget-container');
+    inputPart.appendChild(widgetContainer);
+    container.appendChild(inputPart);
+
+    widgetContainer.appendChild(myWidget.domNode);
+}
+```
+
+**Design recommendation for new components:** Avoid deeply nested CSS selectors that require specific ancestor elements. Use self-contained class names (e.g., `.my-widget .my-element` rather than `.parent-view .parent-part > .wrapper .my-element`). This makes components easier to fixture and reuse.
+
+## Services
+
+### Using createEditorServices
+
+`createEditorServices` pre-registers these services: `IAccessibilityService`, `IKeybindingService`, `IClipboardService`, `IOpenerService`, `INotificationService`, `IDialogService`, `IUndoRedoService`, `ILanguageService`, `IConfigurationService`, `IStorageService`, `IThemeService`, `IModelService`, `ICodeEditorService`, `IContextKeyService`, `ICommandService`, `ITelemetryService`, `IHoverService`, `IUserInteractionService`, and more.
+
+### Additional services
+
+Register extra services via `additionalServices`:
+
+```typescript
+createEditorServices(disposableStore, {
+    additionalServices: (reg) => {
+        // Class-based (instantiated by DI):
+        reg.define(IMyService, MyServiceImpl);
+        // Instance-based (pre-constructed):
+        reg.defineInstance(IMyService, myMockInstance);
+    },
+});
+```
+
+### Mocking services
+
+Use the `mock<T>()` helper from `base/test/common/mock.js` to create mock service instances:
+
+```typescript
+import { mock } from '../../../../base/test/common/mock.js';
+
+const myService = new class extends mock<IMyService>() {
+    override someMethod(): string { return 'test'; }
+    override onSomeEvent = Event.None;
+};
+reg.defineInstance(IMyService, myService);
+```
+
+For mock view models or data objects:
+```typescript
+const element = new class extends mock<IChatRequestViewModel>() { }();
+```
+
+## Async Rendering
+
+The component explorer waits **2 animation frames** after the synchronous render function returns. For most components, this is sufficient.
+
+If your render function returns a `Promise`, the component explorer waits for the promise to resolve.
+
+### Pitfall: DOM reparenting causes flickering
+
+Avoid moving rendered widgets between DOM parents after initial render. This causes:
+- Layout recalculation (the widget jumps as `position: absolute` coordinates become invalid)
+- Focus loss (blur events can trigger hide logic in widgets like QuickInput)
+- Screenshot instability (the component explorer may capture an intermediate layout state)
+
+**Bad pattern — reparenting a widget after async wait:**
+```typescript
+async function render({ container }: ComponentFixtureContext): Promise<void> {
+    const host = document.createElement('div');
+    container.appendChild(host);
+    // ... create widget inside host ...
+    await waitForWidget();
+    container.appendChild(widget);  // BAD: reparenting causes flicker
+    host.remove();
+}
+```
+
+**Better pattern — render in-place with the correct DOM structure from the start:**
+```typescript
+function render({ container }: ComponentFixtureContext): void {
+    // Set up the correct DOM structure first, then create the widget inside it
+    const widget = createWidget(container);
+    container.appendChild(widget.domNode);
+}
+```
+
+If the component absolutely requires async setup (e.g., QuickInput which renders internally), minimize DOM manipulation after the widget appears by structuring the host container to match the final layout from the beginning.
+
+## Adapting Existing Components for Fixtures
+
+Existing components often need small changes to become fixturable. When writing a fixture reveals friction, fix the component — don't work around it in the fixture. Common adaptations:
+
+### Decouple CSS from ancestor context
+
+If a component's CSS only works inside a deeply nested selector like `.workbench .sidebar .my-view .my-widget`, refactor the CSS to be self-contained. Move the styles so they're scoped to the component's own root class:
+
+```css
+/* Before: requires specific ancestors */
+.workbench .sidebar .my-view .my-widget .header { font-weight: bold; }
+
+/* After: self-contained */
+.my-widget .header { font-weight: bold; }
+```
+
+If the component shares styles with its parent (e.g., inheriting background color), use CSS custom properties rather than relying on ancestor selectors.
+
+### Extract hard-coded service dependencies
+
+If a component reaches into singletons or global state instead of using DI, refactor it to accept services through the constructor:
+
+```typescript
+// Before: hard to mock in fixtures
+class MyWidget {
+    private readonly config = getSomeGlobalConfig();
+}
+
+// After: injectable and testable
+class MyWidget {
+    constructor(@IConfigurationService private readonly configService: IConfigurationService) { }
+}
+```
+
+### Add options to control auto-focus and animation
+
+Components that auto-focus on creation or run animations cause flaky screenshots. Add an options parameter:
+
+```typescript
+interface IMyWidgetOptions {
+    shouldAutoFocus?: boolean;
+}
+```
+
+The fixture passes `shouldAutoFocus: false`. The production call site keeps the default behavior.
+
+### Expose internal state for "already completed" rendering
+
+Many components have lifecycle states (loading → active → completed). If the component can only reach the "completed" state through user interaction, add support for initializing directly into that state via constructor data:
+
+```typescript
+// The fixture can pass pre-filled data to render the summary/completed state
+// without simulating the full user interaction flow.
+const carousel: IChatQuestionCarousel = {
+    questions,
+    allowSkip: true,
+    kind: 'questionCarousel',
+    isUsed: true,           // Already completed
+    data: { 'q1': 'answer' }, // Pre-filled answers
+};
+```
+
+### Make DOM node accessible
+
+If a component builds its DOM internally and doesn't expose the root element, add a public `readonly domNode: HTMLElement` property so fixtures can append it to the container.
+
+## Writing Fixture-Friendly Components
+
+When designing new UI components, follow these practices to make them easy to fixture:
+
+### 1. Accept a container element in the constructor
+
+```typescript
+// Good: container is passed in
+class MyWidget {
+    constructor(container: HTMLElement, @IFoo foo: IFoo) {
+        this.domNode = dom.append(container, dom.$('.my-widget'));
+    }
+}
+
+// Also good: widget creates its own domNode for the caller to place
+class MyWidget {
+    readonly domNode: HTMLElement;
+    constructor(@IFoo foo: IFoo) {
+        this.domNode = dom.$('.my-widget');
+    }
+}
+```
+
+### 2. Use dependency injection for all services
+
+All external dependencies should come through DI so fixtures can provide test implementations:
+
+```typescript
+// Good: services injected
+constructor(@IThemeService private readonly themeService: IThemeService) { }
+
+// Bad: reaching into globals
+constructor() { this.theme = getGlobalTheme(); }
+```
+
+### 3. Keep CSS selectors shallow
+
+```css
+/* Good: self-contained, easy to fixture */
+.my-widget .my-header { ... }
+.my-widget .my-list-item { ... }
+
+/* Bad: requires deep ancestor chain */
+.workbench .sidebar .my-view .my-widget .my-header { ... }
+```
+
+### 4. Avoid reading from layout/window services during construction
+
+Components that measure the window or read layout dimensions during construction are hard to fixture because the shadow DOM container has different dimensions than the workbench:
+
+```typescript
+// Prefer: use CSS for sizing, or accept dimensions as parameters
+container.style.width = '400px';
+container.style.height = '300px';
+
+// Avoid: reading from layoutService during construction
+const width = this.layoutService.mainContainerDimension.width;
+```
+
+### 5. Support disabling auto-focus in fixtures
+
+Auto-focus can interfere with screenshot stability. Provide options to disable it:
+
+```typescript
+interface IMyWidgetOptions {
+    shouldAutoFocus?: boolean;  // Fixtures pass false
+}
+```
+
+### 6. Expose the DOM node
+
+The fixture needs to append the widget's DOM to the container. Expose it as a public `readonly domNode: HTMLElement`.
+
+## Multiple Fixture Variants
+
+Create variants to show different states of the same component:
+
+```typescript
+export default defineThemedFixtureGroup({
+    // Different data states
+    Empty: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { items: [] }) }),
+    WithItems: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { items: sampleItems }) }),
+
+    // Different configurations
+    ReadOnly: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { readonly: true }) }),
+    Editable: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { readonly: false }) }),
+
+    // Lifecycle states
+    Loading: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { state: 'loading' }) }),
+    Completed: defineComponentFixture({ render: (ctx) => renderWidget(ctx, { state: 'done' }) }),
+});
+```
+
+## Learnings
+
+Update this section with insights from your fixture development experience!
+
+* Do not copy the component to the fixture and modify it there. Always adapt the original component to be fixture-friendly, then render it in the fixture. This ensures the fixture tests the real component code and lifecycle, rather than a modified version that may hide bugs.
+
+* **Don't recompose child widgets in fixtures.** Never manually instantiate and add a sub-widget (e.g., a toolbar content widget) that the parent component is supposed to create. Instead, configure the parent correctly (e.g., set the right editor option, register the right provider) so the child appears through the normal code path. Manually recomposing hides integration bugs and doesn't test the real widget lifecycle.

+name: fix-ci-failures
+description: Investigate and fix CI failures on a pull request. Use when CI checks fail on a PR branch — covers finding the PR, identifying failed checks, downloading logs and artifacts, extracting the failure cause, and iterating on a fix. Requires the `gh` CLI.
+---
+
+# Investigating and Fixing CI Failures
+
+This skill guides you through diagnosing and fixing CI failures on a PR using the `gh` CLI. The user has the PR branch checked out locally.
+
+## Workflow Overview
+
+1. Identify the current branch and its PR
+2. Check CI status and find failed checks
+3. Download logs for failed jobs
+4. Extract and understand the failure
+5. Fix the issue and push
+
+---
+
+## Step 1: Identify the Branch and PR
+
+```bash
+# Get the current branch name
+git branch --show-current
+
+# Find the PR for this branch
+gh pr view --json number,title,url,statusCheckRollup
+```
+
+If no PR is found, the user may need to specify the PR number.
+
+---
+
+## Step 2: Check CI Status
+
+```bash
+# List all checks and their status (pass/fail/pending)
+gh pr checks --json name,state,link,bucket
+
+# Filter to only failed checks
+gh pr checks --json name,state,link,bucket --jq '.[] | select(.bucket == "fail")'
+```
+
+The `link` field contains the URL to the GitHub Actions job. Extract the **run ID** from the URL — it's the number after `/runs/`:
+```
+https://github.com/microsoft/vscode/actions/runs/<RUN_ID>/job/<JOB_ID>
+```
+
+If checks are still `IN_PROGRESS`, wait for them to complete before downloading logs:
+```bash
+gh pr checks --watch --fail-fast
+```
+
+---
+
+## Step 3: Get Failed Job Details
+
+```bash
+# List failed jobs in a run (use the run ID from the check link)
+gh run view <RUN_ID> --json jobs --jq '.jobs[] | select(.conclusion == "failure") | {name: .name, id: .databaseId}'
+```
+
+---
+
+## Step 4: Download Failure Logs
+
+There are two approaches depending on the type of failure.
+
+### Option A: View Failed Step Logs Directly
+
+Best for build/compile/lint failures where the error is in the step output:
+
+```bash
+# View only the failed step logs (most useful — shows just the errors)
+gh run view <RUN_ID> --job <JOB_ID> --log-failed
+```
+
+> **Important**: `--log-failed` requires the **entire run** to complete, not just the failed job. If other jobs are still running, this command will block or error. Use **Option C** below to get logs for a completed job while the run is still in progress.
+
+The output can be large. Pipe through `tail` or `grep` to focus:
+```bash
+# Last 100 lines of failed output
+gh run view <RUN_ID> --job <JOB_ID> --log-failed | tail -100
+
+# Search for common error patterns
+gh run view <RUN_ID> --job <JOB_ID> --log-failed | grep -E "Error|FAIL|error TS|AssertionError|failing"
+```
+
+### Option B: Download Artifacts
+
+Best for integration test failures where detailed logs (terminal logs, ext host logs, crash dumps) are uploaded as artifacts:
+
+```bash
+# List available artifacts for a run
+gh run download <RUN_ID> --pattern '*' --dir /dev/null 2>&1 || gh run view <RUN_ID> --json jobs --jq '.jobs[].name'
+
+# Download log artifacts for a specific failed job
+# Artifact naming convention: logs-<platform>-<arch>-<test-type>-<attempt>
+# Examples: logs-linux-x64-electron-1, logs-linux-x64-remote-1
+gh run download <RUN_ID> -n "logs-linux-x64-electron-1" -D /tmp/ci-logs
+
+# Download crash dumps if available
+gh run download <RUN_ID> -n "crash-dump-linux-x64-electron-1" -D /tmp/ci-crashes
+```
+
+> **Tip**: Use the test runner name from the failed check (e.g., "Linux / Electron" → `electron`, "Linux / Remote" → `remote`) and platform map ("Windows" → `windows-x64`, "Linux" → `linux-x64`, "macOS" → `macos-arm64`) to construct the artifact name.
+
+> **Warning**: Log artifacts may be empty if the test runner crashed before producing output (e.g., Electron download failure). In that case, fall back to **Option C**.
+
+### Option C: Download Per-Job Logs via API (works while run is in progress)
+
+When the run is still in progress but the failed job has completed, use the GitHub API to download that job's step logs directly:
+
+```bash
+# Save the full job log to a temp file (can be very large — 30k+ lines)
+gh api repos/microsoft/vscode/actions/jobs/<JOB_ID>/logs > "$TMPDIR/ci-job-log.txt"
+```
+
+Then search the saved file. **Start with `##[error]`** — this is the GitHub Actions error annotation that marks the exact line where the step failed:
+
+```bash
+# Step 1: Find the error annotation (fastest path to the failure)
+grep -n '##\[error\]' "$TMPDIR/ci-job-log.txt"
+
+# Step 2: Read context around the error (e.g., if error is on line 34371, read 200 lines before it)
+sed -n '34171,34371p' "$TMPDIR/ci-job-log.txt"
+```
+
+If `##[error]` doesn't reveal enough, use broader patterns:
+```bash
+# Find test failures, exceptions, and crash indicators
+grep -n -E 'HTTPError|ECONNRESET|ETIMEDOUT|502|exit code|Process completed|node:internal|triggerUncaughtException' "$TMPDIR/ci-job-log.txt" | head -20
+```
+
+> **Why save to a file?** The API response for a full job log can be 30k+ lines. Tool output gets truncated, so always redirect to a file first, then search.
+
+### VS Code Log Artifacts Structure
+
+Downloaded log artifacts typically contain:
+```
+logs-linux-x64-electron-1/
+  main.log              # Main process log
+  terminal.log          # Terminal/pty host log (key for run_in_terminal issues)
+  window1/
+    renderer.log        # Renderer process log
+    exthost/
+      exthost.log       # Extension host log (key for extension test failures)
+```
+
+Key files to examine first:
+- **Test assertion failures**: Check `exthost.log` for the extension host output and stack traces
+- **Terminal/sandbox issues**: Check `terminal.log` for rewriter pipeline, shell integration, and strategy logs
+- **Crash/hang**: Check `main.log` and look for crash dumps artifacts
+
+---
+
+## Step 5: Extract the Failure
+
+### For Test Failures
+
+Look for the test runner output in the failed step log:
+```bash
+# Find failing test names and assertion messages
+gh run view <RUN_ID> --job <JOB_ID> --log-failed | grep -A 5 "failing\|AssertionError\|Expected\|Unexpected"
+```
+
+Common patterns in VS Code CI:
+- **`AssertionError [ERR_ASSERTION]`**: Test assertion failed — check expected vs actual values
+- **`Extension host test runner exit code: 1`**: Integration test suite had failures
+- **`Command produced no output`**: Shell integration may not have captured command output (see terminal.log)
+- **`Error: Timeout`**: Test timed out — could be a hang or slow CI machine
+
+### For Build Failures
+
+```bash
+# Find TypeScript compilation errors
+gh run view <RUN_ID> --job <JOB_ID> --log-failed | grep "error TS"
+
+# Find hygiene/lint errors
+gh run view <RUN_ID> --job <JOB_ID> --log-failed | grep -E "eslint|stylelint|hygiene"
+```
+
+---
+
+## Step 6: Determine if Failures are Related to the PR
+
+Before fixing, determine if the failure is caused by the PR changes or is a pre-existing/infrastructure issue:
+
+1. **Check if the failing test is in code you changed** — if the test is in a completely unrelated area, it may be a flake
+2. **Check the test name** — does it relate to the feature area you modified?
+3. **Look at the failure output** — does it reference code paths your PR touches?
+4. **Check if the same tests fail on main** — if identical failures exist on recent main commits, it's a pre-existing issue
+5. **Look for infrastructure failures** — network timeouts, npm registry errors, and machine-level issues are not caused by code changes
+
+```bash
+# Check recent runs on main for the same workflow
+gh run list --branch main --workflow pr-linux-test.yml --limit 5 --json databaseId,conclusion,displayTitle
+```
+
+### Recognizing Infrastructure / Flaky Failures
+
+Not all CI failures are caused by code changes. Common infrastructure failures:
+
+**Network / Registry issues**:
+- `npm ERR! network`, `ETIMEDOUT`, `ECONNRESET`, `EAI_AGAIN` — npm registry unreachable
+- `error: RPC failed; curl 56`, `fetch-pack: unexpected disconnect` — git network failure
+- `Error: unable to get local issuer certificate` — TLS/certificate issues
+- `rate limit exceeded` — GitHub API rate limiting
+- `HTTPError: Request failed with status code 502` on `electron/electron/releases` — Electron CDN download failure (common in the `node.js integration tests` step, which downloads Electron at runtime)
+
+**Machine / Environment issues**:
+- `No space left on device` — CI disk full
+- `ENOMEM`, `JavaScript heap out of memory` — CI machine ran out of memory
+- `The runner has received a shutdown signal` — CI preemption / timeout
+- `Error: The operation was canceled` — GitHub Actions cancelled the job
+- `Xvfb failed to start` — display server for headless Linux tests failed
+
+**Test flakes** (not infrastructure, but not your fault either):
+- Timeouts on tests that normally pass — slow CI machine
+- Race conditions in async tests
+- Shell integration not reporting exit codes (see terminal.log for `exitCode: undefined`)
+
+**What to do with infrastructure failures**:
+1. **Don't change code** — the failure isn't caused by your PR
+2. **Re-run the failed jobs** via the GitHub UI or:
+   ```bash
+   gh run rerun <RUN_ID> --failed
+   ```
+3. If failures persist across re-runs, check if main is also broken:
+   ```bash
+   gh run list --branch main --limit 10 --json databaseId,conclusion,displayTitle
+   ```
+4. If main is broken too, wait for it to be fixed — your PR is not the cause
+
+---
+
+## Step 7: Fix and Iterate
+
+1. Make the fix locally
+2. Verify compilation: check the `VS Code - Build` task or run `npm run compile-check-ts-native`
+3. Run relevant unit tests locally: `./scripts/test.sh --grep "<pattern>"`
+4. Commit and push:
+   ```bash
+   git add -A
+   git commit -m "fix: <description>"
+   git push
+   ```
+5. Watch CI again:
+   ```bash
+   gh pr checks --watch --fail-fast
+   ```
+

 **Right fix (when producer is known)**: Fix the code that sends malformed data. For example, if an authentication provider passes a stringified URI instead of a `UriComponents` object to a logger creation call, fix that call site to pass the proper object.
 
+## Understanding error construction before fixing
+
+Before proposing any fix, **always find and read the code that constructs the error**. Search the codebase for the error class name or a unique substring of the error message. The construction code reveals:
+
+- **What conditions trigger the error** — thresholds, validation checks, state assertions
+- **What classifications or categories the error encodes** — the error may have subtypes that require different fix strategies
+- **What the error's parameters mean** — numeric values, ratios, or flags embedded in the message often encode diagnostic context
+- **Whether the error is actionable** — some errors are threshold-based warnings where the threshold may be legitimately exceeded by design
+
+Use this understanding to determine the correct fix strategy. The construction code is the source of truth — do NOT assume what the error means from its message alone.
+
+### Example: Listener leak errors
+
+Searching for `ListenerLeakError` leads to `src/vs/base/common/event.ts`, where the construction code reveals:
+
+```typescript
+const kind = topCount / listenerCount > 0.3 ? 'dominated' : 'popular';
+const error = new ListenerLeakError(kind, message, topStack);
+```
+
+Reading this code tells you:
+- The error has two categories based on a ratio
+- **Dominated** (ratio > 30%): one code path accounts for most listeners → that code path is the problem, fix its disposal
+- **Popular** (ratio ≤ 30%): many diverse code paths each contribute a few listeners → the identified stack trace is NOT the root cause; it's just the most identical stack among many. Investigate the emitter and its aggregate subscribers instead
+- For popular leaks: do NOT remove caching/pooling/reuse patterns that appear in the top stack — they exist to solve other problems. If the aggregate count is by design (e.g., many menus subscribing to a shared context key service), close the issue as "not planned"
+
+This analysis came from reading the construction code, not from memorized rules about listener leaks.
+
 ## Guidelines
 
 - Prefer enriching error messages over adding try/catch guards

+name: integration-tests
+description: Use when running integration tests in the VS Code repo. Covers scripts/test-integration.sh (macOS/Linux) and scripts/test-integration.bat (Windows), their supported arguments for filtering, and the difference between node.js integration tests and extension host tests.
+---
+
+# Running Integration Tests
+
+Integration tests in VS Code are split into two categories:
+
+1. **Node.js integration tests** - files ending in `.integrationTest.ts` under `src/`. These run in Electron via the same Mocha runner as unit tests.
+2. **Extension host tests** - tests embedded in built-in extensions under `extensions/` (API tests, Git tests, TypeScript tests, etc.). These launch a full VS Code instance with `--extensionDevelopmentPath`.
+
+## Scripts
+
+- **macOS / Linux:** `./scripts/test-integration.sh [options]`
+- **Windows:** `.\scripts\test-integration.bat [options]`
+
+When run **without filters**, both scripts execute all node.js integration tests followed by all extension host tests.
+
+When run **with `--run` or `--runGlob`** (without `--suite`), only the node.js integration tests are run and the filter is applied. Extension host tests are skipped since these filters are node.js-specific.
+
+When run **with `--grep` alone** (no `--run`, `--runGlob`, or `--suite`), all tests are run -- both node.js integration tests and all extension host suites -- with the grep pattern forwarded to every test runner.
+
+When run **with `--suite`**, only the matching extension host test suites are run. Node.js integration tests are skipped. Combine `--suite` with `--grep` to filter individual tests within the selected suites.
+
+## Options
+
+### `--run <file>` - Run tests from a specific file
+
+Accepts a **source file path** (starting with `src/`). Works identically to `scripts/test.sh --run`.
+
+```bash
+./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts
+```
+
+### `--runGlob <pattern>` (aliases: `--glob`, `--runGrep`) - Select test files by path
+
+Selects which test **files** to load by matching compiled `.js` file paths against a glob pattern. Overrides the default `**/*.integrationTest.js` glob. Only applies to node.js integration tests (extension host tests are skipped).
+
+```bash
+./scripts/test-integration.sh --runGlob "**/search/**/*.integrationTest.js"
+```
+
+### `--grep <pattern>` (aliases: `-g`, `-f`) - Filter test cases by name
+
+Filters which **test cases** run by matching against their test titles (e.g. `describe`/`test` names). When used alone, the grep is applied to both node.js integration tests and all extension host suites. When combined with `--suite`, only the matched suites run with the grep.
+
+```bash
+./scripts/test-integration.sh --grep "TextSearchProvider"
+```
+
+### `--suite <pattern>` - Run specific extension host test suites
+
+Runs only the extension host test suites whose name matches the pattern. Supports comma-separated values and shell glob patterns (on macOS/Linux). Node.js integration tests are skipped.
+
+Available suite names: `api-folder`, `api-workspace`, `colorize`, `terminal-suggest`, `typescript`, `markdown`, `emmet`, `git`, `git-base`, `ipynb`, `notebook-renderers`, `configuration-editing`, `github-authentication`, `css`, `html`.
+
+```bash
+# Run only Git extension tests
+./scripts/test-integration.sh --suite git
+
+# Run API folder and workspace tests (glob, macOS/Linux only)
+./scripts/test-integration.sh --suite 'api*'
+
+# Run multiple specific suites
+./scripts/test-integration.sh --suite 'git,emmet,typescript'
+
+# Filter tests within a suite by name
+./scripts/test-integration.sh --suite api-folder --grep 'should open'
+```
+
+### `--help`, `-h` - Show help
+
+```bash
+./scripts/test-integration.sh --help
+```
+
+### Other options
+
+All other options (e.g. `--timeout`, `--coverage`, `--reporter`) are forwarded to the underlying `scripts/test.sh` runner for node.js integration tests. These extra options are **not** forwarded to extension host suites when using `--suite`.
+
+## Examples
+
+```bash
+# Run all integration tests (node.js + extension host)
+./scripts/test-integration.sh
+
+# Run a single integration test file
+./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts
+
+# Run integration tests matching a grep pattern
+./scripts/test-integration.sh --grep "TextSearchProvider"
+
+# Run integration tests under a specific area
+./scripts/test-integration.sh --runGlob "**/workbench/**/*.integrationTest.js"
+
+# Run only Git extension host tests
+./scripts/test-integration.sh --suite git
+
+# Run API folder + workspace extension tests (glob)
+./scripts/test-integration.sh --suite 'api*'
+
+# Run multiple extension test suites
+./scripts/test-integration.sh --suite 'git,typescript,emmet'
+
+# Grep for specific tests in the API folder suite
+./scripts/test-integration.sh --suite api-folder --grep 'should open'
+
+# Combine file and grep
+./scripts/test-integration.sh --run src/vs/workbench/services/search/test/browser/search.integrationTest.ts --grep "should search"
+```
+
+## Compilation requirement
+
+Tests run against compiled JavaScript output. Ensure the `VS Code - Build` watch task is running or that compilation has completed before running tests.
+
+## Distinction from unit tests
+
+- **Unit tests** (`.test.ts`) → use `scripts/test.sh` or the `runTests` tool
+- **Integration tests** (`.integrationTest.ts` and extension tests) → use `scripts/test-integration.sh`
+
+Do **not** mix these up: `scripts/test.sh` will not find integration test files unless you explicitly pass `--runGlob **/*.integrationTest.js`, and `scripts/test-integration.sh` is not intended for `.test.ts` files.

+### 10.2 Validating Changes
+
+1. Run `npm run compile-check-ts-native` to run a repo-wide TypeScript compilation check (including `src/vs/sessions/`). This is a fast way to catch TypeScript errors introduced by your changes.
+2. Run `npm run valid-layers-check` to verify layering rules are not violated.
+3. Use `scripts/test.sh` (or `scripts\test.bat` on Windows) for unit tests (add `--grep <pattern>` to filter tests)
+
+**Important** do not run `tsc` to check for TypeScript errors always use above methods to validate TypeScript changes in `src/vs/**`.
+
+### 10.3 Layout Changes
 
 1. **Read `LAYOUT.md` first** — it's the authoritative spec
 2. Use the `agent-sessions-layout` skill for detailed implementation guidance

+name: unit-tests
+description: Use when running unit tests in the VS Code repo. Covers the runTests tool, scripts/test.sh (macOS/Linux) and scripts/test.bat (Windows), and their supported arguments for filtering, globbing, and debugging tests.
+---
+
+# Running Unit Tests
+
+## Preferred: Use the `runTests` tool
+
+If the `runTests` tool is available, **prefer it** over running shell commands. It provides structured output with detailed pass/fail information and supports filtering by file and test name.
+
+- Pass absolute paths to test files via the `files` parameter.
+- Pass test names via the `testNames` parameter to filter which tests run.
+- Set `mode="coverage"` to collect coverage.
+
+Example (conceptual): run tests in `src/vs/editor/test/common/model.test.ts` with test name filter `"should split lines"`.
+
+## Fallback: Shell scripts
+
+When the `runTests` tool is not available (e.g. in CLI environments), use the platform-appropriate script from the repo root:
+
+- **macOS / Linux:** `./scripts/test.sh [options]`
+- **Windows:** `.\scripts\test.bat [options]`
+
+These scripts download Electron if needed and launch the Mocha test runner.
+
+### Commonly used options
+
+#### Bare file paths - Run tests from specific files
+
+Pass source file paths directly as positional arguments. The test runner automatically treats bare `.ts`/`.js` positional arguments as `--run` values.
+
+```bash
+./scripts/test.sh src/vs/editor/test/common/model.test.ts
+```
+
+```bat
+.\scripts\test.bat src\vs\editor\test\common\model.test.ts
+```
+
+Multiple files:
+
+```bash
+./scripts/test.sh src/vs/editor/test/common/model.test.ts src/vs/editor/test/common/range.test.ts
+```
+
+#### `--run <file>` - Run tests from a specific file (explicit form)
+
+Accepts a **source file path** (starting with `src/`). The runner strips the `src/` prefix and the `.ts`/`.js` extension automatically to resolve the compiled module.
+
+```bash
+./scripts/test.sh --run src/vs/editor/test/common/model.test.ts
+```
+
+Multiple files can be specified by repeating `--run`:
+
+```bash
+./scripts/test.sh --run src/vs/editor/test/common/model.test.ts --run src/vs/editor/test/common/range.test.ts
+```
+
+#### `--grep <pattern>` (aliases: `-g`, `-f`) - Filter tests by name
+
+Runs only tests whose full title matches the pattern (passed to Mocha's `--grep`).
+
+```bash
+./scripts/test.sh --grep "should split lines"
+```
+
+Combine with `--run` to filter tests within a specific file:
+
+```bash
+./scripts/test.sh --run src/vs/editor/test/common/model.test.ts --grep "should split lines"
+```
+
+#### `--runGlob <pattern>` (aliases: `--glob`, `--runGrep`) - Run tests matching a glob
+
+Runs all test files matching a glob pattern against the compiled output directory. Useful for running all tests under a feature area.
+
+```bash
+./scripts/test.sh --runGlob "**/editor/test/**/*.test.js"
+```
+
+Note: the glob runs against compiled `.js` files in the output directory, not source `.ts` files.
+
+#### `--coverage` - Generate a coverage report
+
+```bash
+./scripts/test.sh --run src/vs/editor/test/common/model.test.ts --coverage
+```
+
+#### `--timeout <ms>` - Set test timeout
+
+Override the default Mocha timeout for long-running tests.
+
+```bash
+./scripts/test.sh --run src/vs/editor/test/common/model.test.ts --timeout 10000
+```
+
+### Integration tests
+
+Integration tests (files ending in `.integrationTest.ts` or located in `extensions/`) are **not run** by `scripts/test.sh`. Use `scripts/test-integration.sh` (or `scripts/test-integration.bat`) instead. See the `integration-tests` skill for details.
+
+### Compilation requirement
+
+Tests run against compiled JavaScript output. Ensure the `VS Code - Build` watch task is running or that compilation has completed before running tests. Test failures caused by stale output are a common pitfall.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+      controlled by, or is under common control with You. For purposes of this
+      definition, "control" means (a) the power, direct or indirect, to cause
+      the direction or management of such entity, whether by contract or
+      otherwise, or (b) ownership of more than fifty percent (50%) of the
+      outstanding shares or beneficial ownership of such entity.
+
+
+2. License Grants and Conditions
+
+2.1. Grants
+
+     Each Contributor hereby grants You a world-wide, royalty-free,
+     non-exclusive license:
+
+     a. under intellectual property rights (other than patent or trademark)
+        Licensable by such Contributor to use, reproduce, make available,
+        modify, display, perform, distribute, and otherwise exploit its
+        Contributions, either on an unmodified basis, with Modifications, or as
+        part of a Larger Work; and
+
+     b. under Patent Claims of such Contributor to make, use, sell, offer for
+        sale, have made, import, and otherwise transfer either its Contributions
+        or its Contributor Version.
+
+2.2. Effective Date
+
+     The licenses granted in Section 2.1 with respect to any Contribution become
+     effective for each Contribution on the date the Contributor first distributes
+     such Contribution.
+
+2.3. Limitations on Grant Scope
+
+     The licenses granted in this Section 2 are the only rights granted under this
+     License. No additional rights or licenses will be implied from the distribution
+     or licensing of Covered Software under this License. Notwithstanding Section
+     2.1(b) above, no patent license is granted by a Contributor:
+
+     a. for any code that a Contributor has removed from Covered Software; or
+
+     b. for infringements caused by: (i) Your and any other third party’s
+        modifications of Covered Software, or (ii) the combination of its
+        Contributions with other software (except as part of its Contributor
+        Version); or
+
+     c. under Patent Claims infringed by Covered Software in the absence of its
+        Contributions.
+
+     This License does not grant any rights in the trademarks, service marks, or
+     logos of any Contributor (except as may be necessary to comply with the
+     notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+     No Contributor makes additional grants as a result of Your choice to
+     distribute the Covered Software under a subsequent version of this License
+     (see Section 10.2) or under the terms of a Secondary License (if permitted
+     under the terms of Section 3.3).
+
+2.5. Representation
+
+     Each Contributor represents that the Contributor believes its Contributions
+     are its original creation(s) or it has sufficient rights to grant the
+     rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+     This License is not intended to limit any rights You have under applicable
+     copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+     Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+     All distribution of Covered Software in Source Code Form, including any
+     Modifications that You create or to which You contribute, must be under the
+     terms of this License. You must inform recipients that the Source Code Form
+     of the Covered Software is governed by the terms of this License, and how
+     they can obtain a copy of this License. You may not attempt to alter or
+     restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+     If You distribute Covered Software in Executable Form then:
+
+     a. such Covered Software must also be made available in Source Code Form,
+        as described in Section 3.1, and You must inform recipients of the
+        Executable Form how they can obtain a copy of such Source Code Form by
+        reasonable means in a timely manner, at a charge no more than the cost
+        of distribution to the recipient; and
+
+     b. You may distribute such Executable Form under the terms of this License,
+        or sublicense it under different terms, provided that the license for
+        the Executable Form does not attempt to limit or alter the recipients’
+        rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+     You may create and distribute a Larger Work under terms of Your choice,
+     provided that You also comply with the requirements of this License for the
+     Covered Software. If the Larger Work is a combination of Covered Software
+     with a work governed by one or more Secondary Licenses, and the Covered
+     Software is not Incompatible With Secondary Licenses, this License permits
+     You to additionally distribute such Covered Software under the terms of
+     such Secondary License(s), so that the recipient of the Larger Work may, at
+     their option, further distribute the Covered Software under the terms of
+     either this License or such Secondary License(s).
+
+3.4. Notices
+
+     You may not remove or alter the substance of any license notices (including
+     copyright notices, patent notices, disclaimers of warranty, or limitations
+     of liability) contained within the Source Code Form of the Covered
+     Software, except that You may alter any license notices to the extent
+     required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+     You may choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of Covered
+     Software. However, You may do so only on Your own behalf, and not on behalf
+     of any Contributor. You must make it absolutely clear that any such
+     warranty, support, indemnity, or liability obligation is offered by You
+     alone, and You hereby agree to indemnify every Contributor for any
+     liability incurred by such Contributor as a result of warranty, support,
+     indemnity or liability terms You offer. You may include additional
+     disclaimers of warranty and limitations of liability specific to any
+     jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+   If it is impossible for You to comply with any of the terms of this License
+   with respect to some or all of the Covered Software due to statute, judicial
+   order, or regulation then You must: (a) comply with the terms of this License
+   to the maximum extent possible; and (b) describe the limitations and the code
+   they affect. Such description must be placed in a text file included with all
+   distributions of the Covered Software under this License. Except to the
+   extent prohibited by statute or regulation, such description must be
+   sufficiently detailed for a recipient of ordinary skill to be able to
+   understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+     fail to comply with any of its terms. However, if You become compliant,
+     then the rights granted under this License from a particular Contributor
+     are reinstated (a) provisionally, unless and until such Contributor
+     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+     if such Contributor fails to notify You of the non-compliance by some
+     reasonable means prior to 60 days after You have come back into compliance.
+     Moreover, Your grants from a particular Contributor are reinstated on an
+     ongoing basis if such Contributor notifies You of the non-compliance by
+     some reasonable means, this is the first time You have received notice of
+     non-compliance with this License from such Contributor, and You become
+     compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+     infringement claim (excluding declaratory judgment actions, counter-claims,
+     and cross-claims) alleging that a Contributor Version directly or
+     indirectly infringes any patent, then the rights granted to You by any and
+     all Contributors for the Covered Software under Section 2.1 of this License
+     shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+     license agreements (excluding distributors and resellers) which have been
+     validly granted by You or Your distributors under this License prior to
+     termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+   Covered Software is provided under this License on an "as is" basis, without
+   warranty of any kind, either expressed, implied, or statutory, including,
+   without limitation, warranties that the Covered Software is free of defects,
+   merchantable, fit for a particular purpose or non-infringing. The entire
+   risk as to the quality and performance of the Covered Software is with You.
+   Should any Covered Software prove defective in any respect, You (not any
+   Contributor) assume the cost of any necessary servicing, repair, or
+   correction. This disclaimer of warranty constitutes an essential part of this
+   License. No use of  any Covered Software is authorized under this License
+   except under this disclaimer.
+
+7. Limitation of Liability
+
+   Under no circumstances and under no legal theory, whether tort (including
+   negligence), contract, or otherwise, shall any Contributor, or anyone who
+   distributes Covered Software as permitted above, be liable to You for any
+   direct, indirect, special, incidental, or consequential damages of any
+   character including, without limitation, damages for lost profits, loss of
+   goodwill, work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses, even if such party shall have been
+   informed of the possibility of such damages. This limitation of liability
+   shall not apply to liability for death or personal injury resulting from such
+   party’s negligence to the extent applicable law prohibits such limitation.
+   Some jurisdictions do not allow the exclusion or limitation of incidental or
+   consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+   Any litigation relating to this License may be brought only in the courts of
+   a jurisdiction where the defendant maintains its principal place of business
+   and such litigation shall be governed by laws of that jurisdiction, without
+   reference to its conflict-of-law provisions. Nothing in this Section shall
+   prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+   This License represents the complete agreement concerning the subject matter
+   hereof. If any provision of this License is held to be unenforceable, such
+   provision shall be reformed only to the extent necessary to make it
+   enforceable. Any law or regulation which provides that the language of a
+   contract shall be construed against the drafter shall not be used to construe
+   this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+      Mozilla Foundation is the license steward. Except as provided in Section
+      10.3, no one other than the license steward has the right to modify or
+      publish new versions of this License. Each version will be given a
+      distinguishing version number.
+
+10.2. Effect of New Versions
+
+      You may distribute the Covered Software under the terms of the version of
+      the License under which You originally received the Covered Software, or
+      under the terms of any subsequent version published by the license
+      steward.
+
+10.3. Modified Versions
+
+      If you create software not governed by this License, and you want to
+      create a new license for such software, you may create and use a modified
+      version of this License if you rename the license and remove any
+      references to the name of the license steward (except to note that such
+      modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
+      If You choose to distribute Source Code Form that is Incompatible With
+      Secondary Licenses under the terms of this version of the License, the
+      notice described in Exhibit B of this License must be attached.
+
+Exhibit A - Source Code Form License Notice
+
+      This Source Code Form is subject to the
+      terms of the Mozilla Public License, v.
+      2.0. If a copy of the MPL was not
+      distributed with this file, You can
+      obtain one at
+      http://mozilla.org/MPL/2.0/.
+
+If it is not possible or desirable to put the notice in a particular file, then
+You may include the notice in a location (such as a LICENSE file in a relevant
+directory) where a recipient would be likely to look for such a notice.
+
+You may add additional accurate notices of copyright ownership.
+
+Exhibit B - "Incompatible With Secondary Licenses" Notice
+
+      This Source Code Form is "Incompatible
+      With Secondary Licenses", as defined by
+      the Mozilla Public License, v. 2.0.

Tests in `test/nls-sourcemap.test.ts`.
 
 4. **`convertPrivateFields` source map adjustment** (`private-to-property.ts`) - `convertPrivateFields` returns its sorted edits as `TextEdit[]`. `adjustSourceMap()` uses `SourceMapConsumer` to walk every mapping, adjusts generated columns based on cumulative edit shifts per line, and rebuilds with `SourceMapGenerator`. The post-processing loop in `index.ts` saves pre-mangle content + edits per JS file, then applies `adjustSourceMap` to the corresponding `.map`. Tests in `test/private-to-property.test.ts`.
 
-### Not Yet Fixed
+5. **`postProcessNLS` source map adjustment** (`nls-plugin.ts`, `index.ts`) — `postProcessNLS` now returns `{ code, edits }` where `edits` is a `TextEdit[]` tracking each replacement's byte offset. The bundle loop in `index.ts` chains `adjustSourceMap` calls: first for mangle edits, then for NLS edits, so both transforms are accurately reflected in the final `.map` file. Tests in `test/nls-sourcemap.test.ts`.
 
-**`postProcessNLS` column drift** - Replaces NLS placeholders with short indices in bundled output without updating `.map` files. Shifts columns but never lines, so line-level debugging and crash reporting work correctly. Fixing would require tracking replacement offsets through regex matches and adjusting the source map, similar to `adjustSourceMap`.
+6. **`adjustSourceMap` unmapped segment preservation** (`private-to-property.ts`) — Previously, `adjustSourceMap()` silently dropped mappings where `source === null`. These unmapped segments create essential "gaps" that prevent `originalPositionFor()` from wrongly interpolating between distant valid mappings on the same minified line. Now emits them as generated-only mappings. Also preserves `sourceRoot` from the input map.
 
 ### Key Technical Details
 
@@ -241,6 +241,71 @@ Two categories of corruption:
 
 **Plugin interaction:** Both the NLS plugin and `fileContentMapperPlugin` register `onLoad({ filter: /\.ts$/ })`. In esbuild, the first `onLoad` to return non-`undefined` wins. The NLS plugin is `unshift`ed (runs first), so files with NLS calls skip `fileContentMapperPlugin`. This is safe in practice since `product.ts` (which has `BUILD->INSERT_PRODUCT_CONFIGURATION`) has no localize calls.
 
+### Still Broken — Full Production Build (`npm run gulp vscode-min`)
+
+**Symptom:** Source maps are totally broken in the minified production build. E.g. a breakpoint at `src/vs/editor/browser/editorExtensions.ts` line 308 resolves to `src/vs/editor/common/cursor/cursorMoveCommands.ts` line 732 — a completely different file. This is **cross-file** mapping corruption, not just column drift.
+
+**Status of unit tests:** The fixes above pass in isolated unit tests (small 1–2 file bundles via `esbuild.build` with `minify: true`). The tests verify column drift ≤ 20 and correct line mapping for single-file bundles with NLS. **183 tests pass, 0 failing.** But the full production build bundles hundreds of files into huge minified outputs (e.g. `workbench.desktop.main.js` at ~15 MB) and the source maps break at that scale.
+
+**Suspected root causes (need investigation):**
+
+1. **`generateNLSSourceMap` per-column identity mappings may overwhelm esbuild's source-map composition.** The fix added one mapping per column from edit-end to end-of-line (or next edit). For a long TypeScript line with a `localize()` call near the beginning, this generates hundreds of identity mappings per line. Across hundreds of files, the inline source maps embedded in `onLoad` responses may be extremely large. esbuild must compose these with its own source maps during bundling — it may hit limits, silently drop mappings, or produce incorrect composed maps at this scale. **Mitigation to try:** Instead of per-column mappings, use sparser "checkpoint" mappings (e.g., every N characters) or rely only on boundary mappings and accept some column drift within the NLS-transformed region. The old boundary-only approach was wrong (collapsed all downstream columns), but per-column may be the other extreme.
+
+2. **`adjustSourceMap` may corrupt source indices in large minified bundles.** In a minified bundle, the entire output is on one or very few lines. `adjustSourceMap()` walks every mapping via `SourceMapConsumer.eachMapping()` and adjusts `generatedColumn` using `adjustColumn()`. But when thousands of mappings all share `generatedLine: 1` and there are hundreds of NLS edits on that same line, there may be sorting/ordering bugs: `eachMapping()` returns mappings in generated order by default, but `adjustColumn()` binary-searches through edits sorted by column. If edits cover regions that interleave with mappings from different source files, the cumulative shift calculation might produce wrong columns that then resolve to wrong source files.
+
+3. **Chained `adjustSourceMap` calls (mangle → NLS) may compound errors.** After the first `adjustSourceMap` for mangle edits, the source map's generated columns are updated. The second call for NLS edits uses `nlsEdits` which were computed against `preNLSCode` — but `preNLSCode` is the post-mangle JS, which is what the first `adjustSourceMap` maps from. This chaining _should_ be correct, but needs verification at scale with a real minified bundle.
+
+4. **The `source-map` v0.6.1 library may have precision issues with very large VLQ-encoded maps.** The bundled outputs have source maps with hundreds of thousands of mappings. The library is old (2017) and there may be numerical precision or sorting issues with very large maps. Consider testing with `source-map` v0.7+ or the Rust-based `@aspect-build/source-map`.
+
+5. **Alternative approach: skip per-column NLS plugin mappings, fix only `postProcessNLS`.** The NLS plugin `onLoad` replaces `"key"` with `"%%NLS:longPlaceholder%%"` — a length change that only affects columns on affected lines. The subsequent `postProcessNLS` then replaces the long placeholder with a short index. If the `adjustSourceMap` for `postProcessNLS` is correct, it should compensate for both expansions (plugin expansion + post-process contraction). We might not need per-column mappings in `generateNLSSourceMap` at all — just the boundary mapping. The column will drift in the intermediate representation but `adjustSourceMap` for NLS should fix it. **This hypothesis needs testing.**
+
+6. **Alternative approach: do NLS replacement purely in post-processing.** Skip the `onLoad` two-phase approach (placeholder insertion + post-processing replacement) entirely. Instead, run `postProcessNLS` as a single post-processing step that directly replaces `localize("key", "message")` → `localize(0, null)` in the bundled JS output, with proper source-map adjustment via `adjustSourceMap`. This avoids both the inline source map composition complexity and the two-step replacement. The downside is that post-processing must parse/regex-match real `localize()` calls (not easy placeholders), which is more fragile.
+
+**Summary of fixes applied vs status:**
+
+| Bug | Fix | Unit test | Production |
+|-----|-----|-----------|------------|
+| `generateNLSSourceMap` only had boundary mappings → columns collapsed | Added per-column identity mappings after each edit | Pass (drift: 0) | **Broken** — may overwhelm esbuild composition at scale |
+| `postProcessNLS` didn't track edits for source map adjustment | Returns `{ code, edits }`, chained in `index.ts` | Pass | **Broken** — `adjustSourceMap` may corrupt source indices on huge single-line minified output |
+| `adjustSourceMap` dropped unmapped segments | Preserves generated-only mappings + `sourceRoot` | Pass (no regressions) | **Broken** — same cross-file mapping issue |
+
+**Files involved:**
+- `build/next/nls-plugin.ts` — `generateNLSSourceMap()` (per-column mappings), `postProcessNLS()` (returns edits), `replaceInOutput()` (regex replacement)
+- `build/next/private-to-property.ts` — `adjustSourceMap()` (column adjustment)
+- `build/next/index.ts` — bundle post-processing loop (lines ~899–975), chains adjustSourceMap calls
+- `build/next/test/nls-sourcemap.test.ts` — unit tests (pass but don't cover production-scale bundles)
+
+**How to reproduce:**
+```bash
+npm run gulp vscode-min
+# Open out-vscode-min/ in a debugger, set breakpoints in editor files
+# Observe breakpoints resolve to wrong files
+```
+
+**How to debug further:**
+```bash
+# 1. Build with just --nls (no mangle) to isolate NLS from mangle issues
+npx tsx build/next/index.ts bundle --nls --minify --target desktop --out out-debug
+
+# 2. Build with just --mangle-privates (no NLS) to isolate mangle issues
+npx tsx build/next/index.ts bundle --mangle-privates --minify --target desktop --out out-debug
+
+# 3. Build with neither (baseline — does esbuild's own map work?)
+npx tsx build/next/index.ts bundle --minify --target desktop --out out-debug
+
+# 4. Compare .map files across the three builds to find where mappings diverge
+
+# 5. Validate a specific mapping in the large bundle:
+node -e "
+const {SourceMapConsumer} = require('source-map');
+const fs = require('fs');
+const map = JSON.parse(fs.readFileSync('./out-debug/vs/workbench/workbench.desktop.main.js.map','utf8'));
+const c = new SourceMapConsumer(map);
+// Look up a known position and see which source file it resolves to
+console.log(c.originalPositionFor({line: 1, column: XXXX}));
+"
+```

+# Contributing to Built-In Extensions
+
+This directory contains built-in extensions that ship with VS Code.
+
+## Basic Structure
+
+A typical TypeScript-based built-in extension has the following structure:
+
+- `package.json`: extension manifest.
+- `src/`: Main directory for TypeScript source code.
+- `tsconfig.json`: primary TypeScript config. This should inherit from `tsconfig.base.json`.
+- `esbuild.mts`: esbuild build script used for production builds.
+- `.vscodeignore`: Ignore file list. You can copy this from an existing extension.
+
+TypeScript-based extensions have the following output structure:
+
+- `out`: Output directory for development builds
+- `dist`: Output directory for production builds.
+
+
+## Enabling an Extension in the Browser
+
+By default extensions will only target desktop. To enable an extension in browsers as well:
+
+- Add a `"browser"` entry in `package.json` pointing to the browser bundle (for example `"./dist/browser/extension"`).
+- Add `tsconfig.browser.json` that typechecks only browser-safe sources.
+- Add an `esbuild.browser.mts` file. This should set `platform: 'browser'`.
+
+Make sure the browser build of the extension only uses browser-safe APIs. If an extension needs different behavior between desktop and web, you can create distinct entrypoints for each target:
+
+- `src/extension.ts`: Desktop entrypoint.
+- `src/extension.browser.ts`: Browser entrypoint. Make sure `esbuild.browser.mts` builds this and that `tsconfig.browser.json` targets it.

+# Protocol versioning instructions
+
+This directory contains the protocol version system. Read this before modifying any protocol types.
+
+## Overview
+
+The protocol has **living types** (in `sessionState.ts`, `sessionActions.ts`) and **version type snapshots** (in `versions/v1.ts`, etc.). The `versions/versionRegistry.ts` file contains compile-time checks that enforce backwards compatibility between them, plus a runtime map that tracks which action types belong to which version.
+
+The latest version file is the **tip** — it can be edited. Older version files are frozen.
+
+## Adding optional fields to existing types
+
+This is the most common change. No version bump needed.
+
+1. Add the optional field to the living type in `sessionState.ts` or `sessionActions.ts`:
+   ```typescript
+   export interface IToolCallState {
+       // ...existing fields...
+       readonly mcpServerName?: string; // new optional field
+   }
+   ```
+2. Add the same optional field to the corresponding type in the **tip** version file (currently `versions/v1.ts`):
+   ```typescript
+   export interface IV1_ToolCallState {
+       // ...existing fields...
+       readonly mcpServerName?: string;
+   }
+   ```
+3. Compile. If it passes, you're done. If it fails, you tried to do something incompatible.
+
+You can also skip step 2 — the tip is allowed to be a subset of the living type. But adding it to the tip documents that the field exists at this version.
+
+## Adding new action types
+
+Adding a new action type is backwards-compatible and does **not** require a version bump. Old clients at the same version ignore unknown action types (reducers return state unchanged). Old servers at the same version simply never produce the action.
+
+1. **Add the new action interface** to `sessionActions.ts` and include it in the `ISessionAction` or `IRootAction` union.
+2. **Add the action to `ACTION_INTRODUCED_IN`** in `versions/versionRegistry.ts` with the **current** version number. The compiler will force you to do this — if you add a type to the union without a map entry, it won't compile.
+3. **Add the type to the tip version file** (currently `versions/v1.ts`) and add an `AssertCompatible` check in `versions/versionRegistry.ts`.
+4. **Add a reducer case** in `sessionReducers.ts` to handle the new action.
+5. **Update `../../../protocol.md`** to document the new action.
+
+### When to bump the version
+
+Bump `PROTOCOL_VERSION` when you need a **capability boundary** — i.e., a client needs to check "does this server support feature X?" before sending commands or rendering UI. Examples:
+
+- A new **client-sendable** action that requires server-side support (the client must know the server can handle it before sending)
+- A group of related actions that form a new feature area (subagents, model selection, etc.)
+
+When bumping:
+1. **Bump `PROTOCOL_VERSION`** in `versions/versionRegistry.ts`.
+2. **Create the new tip version file** `versions/v{N}.ts`. Copy the previous tip and add your new types. The previous tip is now frozen — do not edit it.
+3. **Add `AssertCompatible` checks** in `versions/versionRegistry.ts` for the new version's types.
+4. **Add `ProtocolCapabilities` fields** in `sessionCapabilities.ts` for the new feature area.
+5. Assign your new action types version N in `ACTION_INTRODUCED_IN`.
+6. **Update `../../../protocol.md`** version history.
+
+## Adding new notification types
+
+Same process as new action types, but use `NOTIFICATION_INTRODUCED_IN` instead of `ACTION_INTRODUCED_IN`.
+
+## Raising the minimum protocol version
+
+This drops support for old clients and lets you delete compatibility cruft.
+
+1. **Raise `MIN_PROTOCOL_VERSION`** in `versions/versionRegistry.ts` from N to N+1.
+2. **Delete `versions/v{N}.ts`**.
+3. **Remove the v{N} `AssertCompatible` checks** and version-grouped type aliases from `versions/versionRegistry.ts`.
+4. **Compile.** The compiler will surface any code that referenced the deleted version types — clean it up.
+5. **Update `../../../protocol.md`** version history.
+
+## What the compiler catches
+
+| Mistake | Compile error |
+|---|---|
+| Remove a field from a living type | `Current extends Frozen` fails in `AssertCompatible` |
+| Change a field's type | `Current extends Frozen` fails in `AssertCompatible` |
+| Add a required field to a living type | `Frozen extends Current` fails in `AssertCompatible` |
+| Add action to union, forget `ACTION_INTRODUCED_IN` entry | Mapped type index is incomplete |
+| Add notification to union, forget `NOTIFICATION_INTRODUCED_IN` entry | Mapped type index is incomplete |
+| Remove action type that a version still references | Version-grouped union no longer extends living union |

+# Agent host design decisions
+
+> **Keep this document in sync with the code.** Any change to the agent-host protocol, tool rendering approach, or architectural boundaries must be reflected here. If you add a new `toolKind`, change how tool-specific data is populated, or modify the separation between agent-specific and generic code, update this document as part of the same change.
+
+Design decisions and principles for the agent-host feature. For process architecture and IPC details, see [architecture.md](architecture.md). For the client-server state protocol, see [protocol.md](protocol.md).
+
+## Agent-agnostic protocol
+
+**The protocol between the agent-host process and clients must remain agent-agnostic.** This is a hard rule.
+
+There are two protocol layers:
+
+1. **`IAgent` interface** (`common/agentService.ts`) - the internal interface that each agent backend (CopilotAgent, MockAgent) implements. It fires `IAgentProgressEvent`s (raw SDK events: `delta`, `tool_start`, `tool_complete`, etc.). This layer is agent-specific.
+
+2. **Sessions state protocol** (`common/state/`) - the client-facing protocol. The server maps raw `IAgentProgressEvent`s into state actions (`session/delta`, `session/toolStart`, etc.) via `agentEventMapper.ts`. Clients receive immutable state snapshots and action streams via JSON-RPC over WebSocket or MessagePort. **This layer is agent-agnostic.**
+
+All agent-specific logic -- translating tool names like `bash`/`view`/`grep` into display strings, extracting command lines from tool parameters, determining rendering hints like `toolKind: 'terminal'` -- lives in `copilotToolDisplay.ts` inside the agent-host process. These display-ready fields are carried on `IAgentToolStartEvent`/`IAgentToolCompleteEvent`, which `agentEventMapper.ts` then maps into `session/toolStart` and `session/toolComplete` state actions.
+
+Clients (renderers) never see agent-specific tool names. They consume `IToolCallState` and `ICompletedToolCall` from the session state tree, which carry generic display-ready fields (`displayName`, `invocationMessage`, `toolKind`, etc.).
+
+## Provider-agnostic renderer contributions
+
+The renderer contributions (`AgentHostSessionHandler`, `AgentHostSessionListController`, `AgentHostLanguageModelProvider`) are **completely generic**. They receive all provider-specific details via `IAgentHostSessionHandlerConfig`:
+
+```typescript
+interface IAgentHostSessionHandlerConfig {
+    readonly provider: AgentProvider;    // 'copilot'
+    readonly agentId: string;            // e.g. 'agent-host'
+    readonly sessionType: string;        // e.g. 'agent-host'
+    readonly fullName: string;           // e.g. 'Agent Host - Copilot'
+    readonly description: string;
+}
+```
+
+A single `AgentHostContribution` discovers agents via `listAgents()` and dynamically registers each one. Adding a new provider means adding a new `IAgent` implementation in the server process. No changes needed to the handler, list controller, or model provider.
+
+## State-based rendering
+
+The renderer subscribes to session state via `SessionClientState` (write-ahead reconciliation) and converts immutable state changes to `IChatProgress[]` via `stateToProgressAdapter.ts`. This adapter is the only place that inspects protocol state fields like `toolKind`:
+
+- **Shell commands** (`toolKind: 'terminal'`): Converted to `IChatTerminalToolInvocationData` with the command in a syntax-highlighted code block, output displayed below, and exit code for success/failure styling.
+- **Everything else**: Converted to `ChatToolInvocation` using `invocationMessage` (while running) and `pastTenseMessage` (when complete).
+
+The adapter never checks tool names - it operates purely on the generic state fields.
+
+## Copilot SDK tool name mapping
+
+The Copilot CLI uses built-in tools. Tool names and parameter shapes are not typed in the SDK (`toolName` is `string`) - they come from the CLI server. The interfaces in `copilotToolDisplay.ts` are derived from observing actual CLI events.
+
+| SDK tool name | Display name | Rendering |
+|---|---|---|
+| `bash` | Bash | Terminal (`toolKind: 'terminal'`, language `shellscript`) |
+| `powershell` | PowerShell | Terminal (`toolKind: 'terminal'`, language `powershell`) |
+| `view` | View File | Progress message |
+| `edit` | Edit File | Progress message |
+| `write` | Write File | Progress message |
+| `grep` | Search | Progress message |
+| `glob` | Find Files | Progress message |
+| `web_search` | Web Search | Progress message |
+
+This mapping lives in `copilotToolDisplay.ts` and is the only place that knows about Copilot-specific tool names.
+
+## Model ownership
+
+The SDK makes its own LM requests using the GitHub token. VS Code does not make direct LM calls for agent-host sessions.
+
+Each agent's models are published to root state via the `root/agentsChanged` action. The renderer's `AgentHostLanguageModelProvider` exposes these in the model picker. The selected model ID is passed to `createSession({ model })`. The `sendChatRequest` method throws - agent-host models aren't usable for direct LM calls, only for the agent loop.
+
+## Setting gate
+
+The entire feature is controlled by `chat.agentHost.enabled` (default `false`), defined as `AgentHostEnabledSettingId` in `agentService.ts`. When disabled:
+- The main process does not spawn the agent host utility process
+- The renderer does not connect via MessagePort
+- No agents, sessions, or model providers are registered
+- No agent-host entries appear in the UI
+
+## Multi-client state synchronization
+
+The sessions process uses a redux-like state model where all mutations flow through a discriminated union of actions processed by pure reducer functions. This design supports multiple connected clients seeing a synchronized view:
+
+- **Server-authoritative state**: The server holds the canonical state tree. Clients receive snapshots and incremental actions.
+- **Write-ahead with reconciliation**: Clients optimistically apply their own actions locally (e.g., approving a permission, sending a message) and reconcile when the server echoes them back. Actions carry `(clientId, clientSeq)` tags for echo matching.
+- **Lazy loading**: Clients connect with lightweight session metadata (enough for a sidebar list) and subscribe to full session state on demand. Large content (images, tool outputs) uses `ContentRef` placeholders fetched separately.
+- **Forward-compatible versioning**: A single protocol version number maps to a `ProtocolCapabilities` object. Newer clients check capabilities before using features unavailable on older servers.
+
+Details and type definitions are in [protocol.md](protocol.md) and `common/state/`.

+# Sessions process protocol
+
+> **Keep this document in sync with the code.** Changes to the state model, action types, protocol messages, or versioning strategy must be reflected here. Implementation lives in `common/state/`.
+
+> **Pre-production.** This protocol is under active development and is not shipped yet. Breaking changes to wire types, actions, and state shapes are fine — do not worry about backward compatibility until the protocol is in production. The versioning machinery exists for future use.
+
+For process architecture and IPC details, see [architecture.md](architecture.md). For design decisions, see [design.md](design.md).
+
+## Goal
+
+The sessions process is a portable, standalone server that multiple clients can connect to. Clients see a synchronized view of sessions and can send commands that are reflected back as state-changing actions. The protocol is designed around four requirements:
+
+1. **Synchronized multi-client state** — an immutable, redux-like state tree mutated exclusively by actions flowing through pure reducers.
+2. **Lazy loading** — clients subscribe to state by URI and load data on demand. The session list is fetched imperatively. Large content (images, long tool outputs) is stored by reference and fetched separately.
+3. **Write-ahead with reconciliation** — clients optimistically apply their own actions locally, then reconcile when the server echoes them back alongside any concurrent actions from other clients or the server itself.
+4. **Forward-compatible versioning** — newer clients can connect to older servers. A single protocol version number maps to a capabilities object; clients check capabilities before using features.
+
+## Protocol development checklist
+
+Use this checklist when adding a new action, command, state field, or notification to the protocol.
+
+### Adding a new action type
+
+1. **Write an E2E test first** in `protocolWebSocket.integrationTest.ts` that exercises the action end-to-end through the WebSocket server. The test should fail until the implementation is complete.
+2. **Add mock agent support** if the test needs a new prompt/behavior in `mockAgent.ts`.
+3. **Define the action interface** in `sessionActions.ts`. Extend `ISessionActionBase` (for session-scoped) or define a standalone root action. Add it to the `ISessionAction` or `IRootAction` union.
+4. **Add a reducer case** in `sessionReducers.ts`. The switch must remain exhaustive — the compiler will error if a case is missing.
+5. **Add a v1 wire type** in `versions/v1.ts`. Mirror the action interface shape. Add it to the `IV1_SessionAction` or `IV1_RootAction` union.
+6. **Register in `versionRegistry.ts`**:
+   - Import the new `IV1_*` type.
+   - Add an `AssertCompatible` check.
+   - Add the type to the `ISessionAction_v1` union.
+   - Add the type string to the suppress-warnings `void` expression.
+   - Add an entry to `ACTION_INTRODUCED_IN` (compiler enforces this).
+7. **Update `protocol.md`** (this file) — add the action to the Actions table.
+8. **Verify the E2E test passes.**
+
+### Adding a new command
+
+1. **Write an E2E test first** in `protocolWebSocket.integrationTest.ts`. The test should fail until the implementation is complete.
+2. **Define the request params and result interfaces** in `sessionProtocol.ts`.
+3. **Handle it in `protocolServerHandler.ts`** `_handleRequestAsync()`. The method returns the result; the caller wraps it in a JSON-RPC response or error automatically.
+4. **Add the handler** in `protocolServerHandler.ts` request handler map. If the command requires I/O or agent interaction, it delegates to `IAgentService`. Implement the backing method in `AgentService` (or `AgentSideEffects` for operations that involve agent backends).
+5. **Update `protocol.md`** — add the command to the Commands table.
+6. **Verify the E2E test passes.**
+
+### Adding a new state field
+
+1. **Add the field** to the relevant interface in `sessionState.ts` (e.g. `ISessionSummary`, `IActiveTurn`, `ITurn`).
+2. **Update the factory** (`createSessionState()`, `createActiveTurn()`) to initialize the field.
+3. **Add to the v1 wire type** in `versions/v1.ts`. Optional fields are safe; required fields break the bidirectional `AssertCompatible` check (intentionally — add as optional or bump the protocol version).
+4. **Update reducers** in `sessionReducers.ts` if the field needs to be mutated by actions.
+5. **Update `finalizeTurn()`** if the field lives on `IActiveTurn` and should transfer to `ITurn` on completion.
+
+### Adding a new notification
+
+1. **Write an E2E test first** in `protocolWebSocket.integrationTest.ts`.
+2. **Define the notification interface** in `sessionActions.ts`. Add it to the `INotification` union.
+3. **Add to `NOTIFICATION_INTRODUCED_IN`** in `versionRegistry.ts`.
+4. **Emit it** from `SessionStateManager` or the relevant server-side code.
+5. **Verify the E2E test passes.**
+
+### Adding mock agent support (for testing)
+
+1. **Add a prompt case** in `mockAgent.ts` `sendMessage()` to trigger the behavior.
+2. **Fire the corresponding `IAgentProgressEvent`** via `_fireSequence()` or manually through `_onDidSessionProgress`.
+
+
+## URI-based subscriptions
+
+All state is identified by URIs. Clients subscribe to a URI to receive its current state snapshot and subsequent action updates. This is the single universal mechanism for state synchronization:
+
+- **Root state** (`agenthost:root`) — always-present global state (agents and their models). Clients subscribe to this on connect.
+- **Session state** (`copilot:/<uuid>`, etc.) — per-session state loaded on demand. Clients subscribe when opening a session.
+
+The `subscribe(uri)` / `unsubscribe(uri)` mechanism works identically for all resource types.
+
+## State model
+
+### Root state
+
+Subscribable at `agenthost:root`. Contains global, lightweight data that all clients need. **Does not contain the session list** — that is fetched imperatively via RPC (see Commands).
+
+```
+RootState {
+    agents: AgentInfo[]
+}
+```
+
+Each `AgentInfo` includes the models available for that agent:
+
+```
+AgentInfo {
+    provider: string
+    displayName: string
+    description: string
+    models: ModelInfo[]
+}
+```
+
+### Session state
+
+Subscribable at the session's URI (e.g. `copilot:/<uuid>`). Contains the full state for a single session.
+
+```
+SessionState {
+    summary: SessionSummary
+    lifecycle: 'creating' | 'ready' | 'creationFailed'
+    creationError?: ErrorInfo
+    turns: Turn[]
+    activeTurn: ActiveTurn | undefined
+}
+```
+
+`lifecycle` tracks the asynchronous creation process. When a client creates a session, it picks a URI, sends the command, and subscribes immediately. The initial snapshot has `lifecycle: 'creating'`. The server asynchronously initializes the backend and dispatches `session/ready` or `session/creationFailed`.
+
+```
+Turn {
+    id: string
+    userMessage: UserMessage
+    responseParts: ResponsePart[]
+    toolCalls: CompletedToolCall[]
+    usage: UsageInfo | undefined
+    state: 'complete' | 'cancelled' | 'error'
+}
+
+ActiveTurn {
+    id: string
+    userMessage: UserMessage
+    streamingText: string
+    responseParts: ResponsePart[]
+    toolCalls: Record<toolCallId, ToolCallState>
+    pendingPermissions: Record<requestId, PermissionRequest>
+    reasoning: string
+    usage: UsageInfo | undefined
+}
+```
+
+### Session list
+
+The session list can be arbitrarily large and is **not** part of the state tree. Instead:
+- Clients fetch the list imperatively via `listSessions()` RPC.
+- The server sends lightweight **notifications** (`sessionAdded`, `sessionRemoved`) so connected clients can update a local cache without re-fetching.
+
+Notifications are ephemeral — not processed by reducers, not stored in state, not replayed on reconnect. On reconnect, clients re-fetch the list.
+
+### Content references
+
+Large content is **not** inlined in state. A `ContentRef` placeholder is used instead:
+
+```
+ContentRef {
+    uri: string             // scheme://sessionId/contentId
+    sizeHint?: number
+    mimeType?: string
+}
+```
+
+Clients fetch content separately via `fetchContent(uri)`. This keeps the state tree small and serializable.
+
+## Actions
+
+Actions are the sole mutation mechanism for subscribable state. They form a discriminated union keyed by `type`. Every action is wrapped in an `ActionEnvelope` for sequencing and origin tracking.
+
+### Action envelope
+
+```
+ActionEnvelope {
+    action: Action
+    serverSeq: number                                     // monotonic, assigned by server
+    origin: { clientId: string, clientSeq: number } | undefined  // undefined = server-originated
+    rejectionReason?: string                              // present when the server rejected the action
+}
+```
+
+### Root actions
+
+These mutate the root state. **All root actions are server-only** — clients observe them but cannot produce them.
+
+| Type | Payload | When |
+|---|---|---|
+| `root/agentsChanged` | `AgentInfo[]` | Available agent backends or their models changed |
+
+### Session actions
+
+All scoped to a session URI. Some are server-only (produced by the agent backend), others can be dispatched directly by clients.
+
+When a client dispatches an action, the server applies it to the state and also reacts to it as a side effect (e.g., `session/turnStarted` triggers agent processing, `session/turnCancelled` aborts it). This avoids a separate command→action translation layer for the common interactive cases.
+
+| Type | Payload | Client-dispatchable? | When |
+|---|---|---|---|
+| `session/ready` | — | No | Session backend initialized successfully |
+| `session/creationFailed` | `ErrorInfo` | No | Session backend failed to initialize |
+| `session/turnStarted` | `turnId, UserMessage` | Yes | User sent a message; server starts processing |
+| `session/delta` | `turnId, content` | No | Streaming text chunk from assistant |
+| `session/responsePart` | `turnId, ResponsePart` | No | Structured content appended |
+| `session/toolStart` | `turnId, ToolCallState` | No | Tool execution began |
+| `session/toolComplete` | `turnId, toolCallId, ToolCallResult` | No | Tool execution finished |
+| `session/permissionRequest` | `turnId, PermissionRequest` | No | Permission needed from user |
+| `session/permissionResolved` | `turnId, requestId, approved` | Yes | Permission granted or denied |
+| `session/turnComplete` | `turnId` | No | Turn finished (assistant idle) |
+| `session/turnCancelled` | `turnId` | Yes | Turn was aborted; server stops processing |
+| `session/error` | `turnId, ErrorInfo` | No | Error during turn processing |
+| `session/titleChanged` | `title` | No | Session title updated |
+| `session/usage` | `turnId, UsageInfo` | No | Token usage report |
+| `session/reasoning` | `turnId, content` | No | Reasoning/thinking text |
+| `session/modelChanged` | `model` | Yes | Model changed for this session |
+
+### Notifications
+
+Notifications are ephemeral broadcasts that are **not** part of the state tree. They are not processed by reducers and are not replayed on reconnect.
+
+| Type | Payload | When |
+|---|---|---|
+| `notify/sessionAdded` | `SessionSummary` | A new session was created |
+| `notify/sessionRemoved` | session `URI` | A session was disposed |
+
+Clients use notifications to maintain a local session list cache. On reconnect, clients should re-fetch via `listSessions()` rather than relying on replayed notifications.
+
+## Commands and client-dispatched actions
+
+Clients interact with the server in two ways:
+
+1. **Dispatching actions** — the client sends an action directly (e.g., `session/turnStarted`, `session/turnCancelled`). The server applies it to state and reacts with side effects. These are write-ahead: the client applies them optimistically.
+2. **Sending commands** — imperative RPCs for operations that don't map to a single state action (session creation, fetching data, etc.).
+
+### Client-dispatched actions
+
+| Action | Server-side effect |
+|---|---|
+| `session/turnStarted` | Begins agent processing for the new turn |
+| `session/permissionResolved` | Unblocks the pending tool execution |
+| `session/turnCancelled` | Aborts the in-progress turn |
+
+### Commands
+
+| Command | Effect |
+|---|---|
+| `createSession(uri, config)` | Server creates session, client subscribes to URI |
+| `disposeSession(session)` | Server disposes session, broadcasts `sessionRemoved` notification |
+| `listSessions(filter?)` | Returns `SessionSummary[]` |
+| `fetchContent(uri)` | Returns content bytes |
+| `fetchTurns(session, range)` | Returns historical turns |
+| `browseDirectory(uri)` | Lists directory entries at a file URI on the server's filesystem |
+
+`browseDirectory(uri)` succeeds only if the target exists and is a directory. If the target does not exist, is not a directory, or cannot be accessed, the server MUST return a JSON-RPC error.
+
+### Session creation flow
+
+1. Client picks a session URI (e.g. `copilot:/<new-uuid>`)
+2. Client sends `createSession(uri, config)` command
+3. Client sends `subscribe(uri)` (can be batched with the command)
+4. Server creates the session in state with `lifecycle: 'creating'` and sends the subscription snapshot
+5. Server asynchronously initializes the agent backend
+6. On success: server dispatches `session/ready` action
+7. On failure: server dispatches `session/creationFailed` action with error details
+8. Server broadcasts `notify/sessionAdded` to all clients
+
+## Client-server protocol
+
+The protocol uses **JSON-RPC 2.0** framing over the transport (WebSocket, MessagePort, etc.).
+
+### Message categories
+
+- **Client → Server notifications** (fire-and-forget): `unsubscribe`, `dispatchAction`
+- **Client → Server requests** (expect a correlated response): `initialize`, `reconnect`, `subscribe`, `createSession`, `disposeSession`, `listSessions`, `fetchTurns`, `fetchContent`, `browseDirectory`
+- **Server → Client notifications** (pushed): `action`, `notification`
+- **Server → Client responses** (correlated to requests by `id`): success result or JSON-RPC error
+
+### Connection handshake
+
+`initialize` is a JSON-RPC **request** — the server MUST respond with a result or error:
+
+```
+1. Client → Server:  { "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { protocolVersion, clientId, initialSubscriptions? } }
+2. Server → Client:  { "jsonrpc": "2.0", "id": 1, "result": { protocolVersion, serverSeq, snapshots[], defaultDirectory? } }
+```
+
+`initialSubscriptions` allows the client to subscribe to root state (and any previously-open sessions on reconnect) in the same round-trip as the handshake. The server returns snapshots for each in the response.
+
+### URI subscription
+
+`subscribe` is a JSON-RPC **request** — the client receives the snapshot as the response result:
+
+```
+Client → Server:  { "jsonrpc": "2.0", "id": 1, "method": "subscribe", "params": { "resource": "copilot:/session-1" } }
+Server → Client:  { "jsonrpc": "2.0", "id": 1, "result": { "resource": ..., "state": ..., "fromSeq": 5 } }
+```
+
+After subscribing, the client receives all actions scoped to that URI with `serverSeq > fromSeq`. Multiple concurrent subscriptions are supported.
+
+`unsubscribe` is a notification (no response needed):
+
+```
+Client → Server:  { "jsonrpc": "2.0", "method": "unsubscribe", "params": { "resource": "copilot:/session-1" } }
+```
+
+### Action delivery
+
+The server broadcasts action envelopes as JSON-RPC notifications:
+
+```
+Server → Client:  { "jsonrpc": "2.0", "method": "action", "params": { "envelope": { action, serverSeq, origin } } }
+```
+
+- Root actions go to all clients subscribed to root state.
+- Session actions go to all clients subscribed to that session's URI.
+
+Protocol notifications (sessionAdded/sessionRemoved) are broadcast similarly:
+
+```
+Server → Client:  { "jsonrpc": "2.0", "method": "notification", "params": { "notification": { type, ... } } }
+```
+
+### Commands as JSON-RPC requests
+
+Commands are JSON-RPC requests. The server returns a result or a JSON-RPC error:
+
+```
+Client → Server:  { "jsonrpc": "2.0", "id": 2, "method": "createSession", "params": { session, provider?, model? } }
+Server → Client:  { "jsonrpc": "2.0", "id": 2, "result": null }
+```
+
+On failure:
+
+```
+Server → Client:  { "jsonrpc": "2.0", "id": 2, "error": { "code": -32603, "message": "No agent for provider" } }
+```
+
+### Client-dispatched actions
+
+Actions are sent as notifications (fire-and-forget, write-ahead):
+
+```
+Client → Server:  { "jsonrpc": "2.0", "method": "dispatchAction", "params": { clientSeq, action } }
+```
+
+### Reconnection
+
+`reconnect` is a JSON-RPC **request**. The server MUST include all replayed data in the response:
+
+```
+Client → Server:  { "jsonrpc": "2.0", "id": 2, "method": "reconnect", "params": { clientId, lastSeenServerSeq, subscriptions } }
+```
+
+If the gap is within the replay buffer, the response contains missed action envelopes:
+```
+Server → Client:  { "jsonrpc": "2.0", "id": 2, "result": { "type": "replay", "actions": [...] } }
+```
+
+If the gap exceeds the buffer, the response contains fresh snapshots:
+```
+Server → Client:  { "jsonrpc": "2.0", "id": 2, "result": { "type": "snapshot", "snapshots": [...] } }
+```
+
+Protocol notifications are **not** replayed — the client should re-fetch the session list.
+
+## Write-ahead reconciliation
+
+### Client-side state
+
+Each client maintains per-subscription:
+- `confirmedState` — last fully server-acknowledged state
+- `pendingActions[]` — optimistically applied but not yet echoed by server
+- `optimisticState` — `confirmedState` with `pendingActions` replayed on top (computed, not stored)
+
+### Reconciliation algorithm
+
+When the client receives an `ActionEnvelope` from the server:
+
+1. **Own action echoed**: `origin.clientId === myId` and matches head of `pendingActions` → pop from pending, apply to `confirmedState`
+2. **Foreign action**: different origin → apply to `confirmedState`, rebase remaining `pendingActions`
+3. **Rejected action**: server echoed with `rejectionReason` present → remove from pending (optimistic effect reverted). The `rejectionReason` MAY be surfaced to the user.
+4. Recompute `optimisticState` from `confirmedState` + remaining `pendingActions`
+
+### Why rebasing is simple
+
+Most session actions are **append-only** (add turn, append delta, add tool call). Pending actions still apply cleanly to an updated confirmed state because they operate on independent data (the turn the client created still exists; the content it appended is additive). The rare true conflict (two clients abort the same turn) is resolved by server-wins semantics.
+
+## Versioning
+
+### Protocol version
+
+Two constants define the version window:
+- `PROTOCOL_VERSION` — the current version that new code speaks.
+- `MIN_PROTOCOL_VERSION` — the oldest version we maintain compatibility with.
+
+Bump `PROTOCOL_VERSION` when:
+- A new feature area requires capability negotiation (e.g., client must know server supports it before sending commands)
+- Behavioral semantics of existing actions change
+
+Adding **optional** fields to existing action/state types does NOT require a bump. Adding **required** fields or removing/renaming fields **is a compile error** (see below).
+
+```
+Version history:
+  1 — Initial: core session lifecycle, streaming, tools, permissions
+```
+
+### Version type snapshots
+
+Each protocol version has a type file (`versions/v1.ts`, `versions/v2.ts`, etc.) that captures the wire format shape of every state type and action type in that version.
+
+The **latest** version file is the editable "tip" — it can be modified alongside the living types in `sessionState.ts` / `sessionActions.ts`. The compiler enforces that all changes are backwards-compatible. When `PROTOCOL_VERSION` is bumped, the previous version file becomes truly frozen and a new tip is created.
+
+The version registry (`versions/versionRegistry.ts`) performs **bidirectional assignability checks** between the version types and the living types:
+
+```typescript
+// AssertCompatible requires BOTH directions:
+//   Current extends Frozen → can't remove fields or change field types
+//   Frozen extends Current → can't add required fields
+// The only allowed evolution is adding optional fields.
+type AssertCompatible<Frozen, Current extends Frozen> = Frozen extends Current ? true : never;
+
+type _check = AssertCompatible<IV1_TurnStartedAction, ITurnStartedAction>;
+```
+
+| Change to living type | Also update tip? | Compile result |
+|---|---|---|
+| Add optional field | Yes, add it to tip too | ✅ Passes |
+| Add optional field | No, only in living type | ✅ Passes (tip is a subset) |
+| Remove a field | — | ❌ `Current extends Frozen` fails |
+| Change a field's type | — | ❌ `Current extends Frozen` fails |
+| Add required field | — | ❌ `Frozen extends Current` fails |
+
+### Exhaustive action→version map
+
+The registry also maintains an exhaustive runtime map:
+
+```typescript
+export const ACTION_INTRODUCED_IN: { readonly [K in IStateAction['type']]: number } = {
+    'root/agentsChanged': 1,
+    'session/turnStarted': 1,
+    // ...every action type must have an entry
+};
+```
+
+The index signature `[K in IStateAction['type']]` means adding a new action to the `IStateAction` union without adding it to this map is a compile error. The developer is forced to pick a version number.
+
+The server uses this for one-line filtering — no if/else chains:
+
+```typescript
+function isActionKnownToVersion(action: IStateAction, clientVersion: number): boolean {
+    return ACTION_INTRODUCED_IN[action.type] <= clientVersion;
+}
+```
+
+### Capabilities
+
+The protocol version maps to a `ProtocolCapabilities` interface for higher-level feature gating:
+
+```typescript
+interface ProtocolCapabilities {
+    // v1 — always present
+    readonly sessions: true;
+    readonly tools: true;
+    readonly permissions: true;
+    // v2+
+    readonly reasoning?: true;
+}
+```
+
+### Forward compatibility
+
+A newer client connecting to an older server:
+1. During handshake, the client learns the server's protocol version from the `initialize` response.
+2. The client derives `ProtocolCapabilities` from the server version.
+3. Command factories check capabilities before dispatching; if unsupported, the client degrades gracefully.
+4. The server only sends action types known to the client's declared version (via `isActionKnownToVersion`).
+5. As a safety net, clients silently ignore actions with unrecognized `type` values.
+
+### Raising the minimum version
+
+When `MIN_PROTOCOL_VERSION` is raised from N to N+1:
+1. Delete `versions/vN.ts`.
+2. Remove the vN compatibility checks from `versions/versionRegistry.ts`.
+3. The compiler surfaces any dead code that only existed for vN compatibility.
+4. Clean up that dead code.
+
+### Backward compatibility
+
+We do not guarantee backward compatibility (older clients connecting to newer servers). Clients should update before the server.
+
+### Adding a new protocol version (cookbook)
+
+1. Bump `PROTOCOL_VERSION` in `versions/versionRegistry.ts`.
+2. Create `versions/v{N}.ts` — freeze the current types (copy from v{N-1} and add your new types).
+3. Add your new action types to the living union in `sessionActions.ts`.
+4. Add entries to `ACTION_INTRODUCED_IN` with version N (compiler forces this).
+5. Add `AssertCompatible` checks for the new types in `versionRegistry.ts`.
+6. Add reducer cases for the new actions (in new functions if desired).
+7. Add capability fields to `ProtocolCapabilities` if needed.
+
+## Reducers
+
+State is mutated by pure reducer functions that take `(state, action) → newState`. The same reducer code runs on both server and client, which is what makes write-ahead possible: the client can locally predict the result of its own action using the same logic the server will run.
+
+```
+rootReducer(state: RootState, action: RootAction): RootState
+sessionReducer(state: SessionState, action: SessionAction): SessionState
+```
+
+Reducers are pure (no side effects, no I/O). Server-side effects (e.g. forwarding a `sendMessage` command to the Copilot SDK) are handled by a separate dispatch layer, not in the reducer.
+
+## File layout
+
+```
+src/vs/platform/agent/common/state/
+├── sessionState.ts          # Immutable state types (RootState, SessionState, Turn, etc.)
+├── sessionActions.ts        # Action + notification discriminated unions, ActionEnvelope
+├── sessionReducers.ts       # Pure reducer functions (rootReducer, sessionReducer)
+├── sessionProtocol.ts       # JSON-RPC message types, request params/results, type guards
+├── sessionCapabilities.ts   # Re-exports version constants + ProtocolCapabilities
+├── sessionClientState.ts    # Client-side state manager (confirmed + pending + reconciliation)
+└── versions/
+    ├── v1.ts                # v1 wire format types (tip — editable, compiler-enforced compat)
+    └── versionRegistry.ts   # Compile-time compat checks + runtime action→version map
+```
+
+## Relationship to existing IPC contract
+
+The existing `IAgentProgressEvent` union in `agentService.ts` captures raw streaming events from the Copilot SDK. The new action types in `sessionActions.ts` are a higher-level abstraction: they represent state transitions rather than SDK events.
+
+In the server process, the mapping is:
+- `IAgentDeltaEvent` → `session/delta` action
+- `IAgentToolStartEvent` → `session/toolStart` action
+- `IAgentIdleEvent` → `session/turnComplete` action
+- etc.
+
+The existing `IAgentService` RPC interface remains unchanged. The new protocol layer sits on top: the sessions process uses `IAgentService` internally to talk to agent backends, and produces actions for connected clients.

+## Chat sessions / background agent architecture
+
+> **Keep this document in sync with the code.** If you change how session types are registered, modify the extension point, or update the agent-host's registration pattern, update this document as part of the same change.
+
+There are **three layers** that connect to form a chat session type (like "Background Agent" / "Copilot CLI"):
+
+### Layer 1: `chatSessions` Extension Point (package.json)
+
+In package.json, the extension contributes to the `"chatSessions"` extension point. Each entry declares a session **type** (used as a URI scheme), a **name** (used as a chat participant name like `@cli`), display metadata, capabilities, slash commands, and a `when` clause for conditional availability.
+
+### Layer 2: VS Code Platform -- Extension Point + Service
+
+On the VS Code side:
+
+- chatSessions.contribution.ts -- Registers the `chatSessions` extension point via `ExtensionsRegistry.registerExtensionPoint`. When extensions contribute to it, the `ChatSessionsService` processes each contribution: it sets up context keys, icons, welcome messages, commands, and -- if `canDelegate` is true -- also **registers a dynamic chat agent**.
+
+- chatSessionsService.ts -- The `IChatSessionsService` interface manages two kinds of providers:
+  - **`IChatSessionItemController`** -- Lists available sessions
+  - **`IChatSessionContentProvider`** -- Provides session content (history + request handler) when you open a specific session
+
+- agentSessions.ts -- The `AgentSessionProviders` enum maps well-known types to their string identifiers:
+  - `Local` = `'local'`
+  - `Background` = `'copilotcli'`
+  - `Cloud` = `'copilot-cloud-agent'`
+  - `Claude` = `'claude-code'`
+  - `Codex` = `'openai-codex'`
+  - `Growth` = `'copilot-growth'`
+  - `AgentHostCopilot` = `'agent-host-copilot'`
+
+### Layer 3: Extension Side Registration
+
+Each session type registers three things via the proposed API:
+
+1. **`vscode.chat.registerChatSessionItemProvider(type, provider)`** -- Provides the list of sessions
+2. **`vscode.chat.createChatParticipant(type, handler)`** -- Creates the chat participant
+3. **`vscode.chat.registerChatSessionContentProvider(type, contentProvider, chatParticipant)`** -- Binds content provider to participant
+
+### Agent Host: Internal (Non-Extension) Registration
+
+The agent-host session types (`agent-host-copilot`) bypass the extension point entirely. A single `AgentHostContribution` discovers available agents from the agent host process via `listAgents()` and dynamically registers each one:
+
+**For each `IAgentDescriptor` returned by `listAgents()`:**
+1. Chat session contribution via `IChatSessionsService.registerChatSessionContribution()`
+2. Session item controller via `IChatSessionsService.registerChatSessionItemController()`
+3. Session content provider via `IChatSessionsService.registerChatSessionContentProvider()`
+4. Language model provider via `ILanguageModelsService.registerLanguageModelProvider()`
+5. Auth token push (only if `descriptor.requiresAuth` is true)
+
+All use the same generic `AgentHostSessionHandler` class, configured with the descriptor's metadata.
+
+### All Entry Points
+
+| # | Entry Point | File |
+|---|-------------|------|
+| 1 | **package.json `chatSessions` contribution** | package.json -- declares type, name, capabilities |
+| 2 | **Extension point handler** | chatSessions.contribution.ts -- processes contributions |
+| 3 | **Service interface** | chatSessionsService.ts -- `IChatSessionsService` |
+| 4 | **Proposed API** | vscode.proposed.chatSessionsProvider.d.ts |
+| 5 | **Agent session provider enum** | agentSessions.ts -- `AgentSessionProviders` |
+| 6 | **Agent Host contribution** | agentHost/agentHostChatContribution.ts -- `AgentHostContribution` (discovers + registers dynamically) |
+| 7 | **Agent Host process** | src/vs/platform/agent/ -- utility process, SDK integration |
+| 8 | **Desktop registration** | electron-browser/chat.contribution.ts -- registers `AgentHostContribution` |

+# Auth Rework: Standards-Based Authentication for the Agent Host Protocol
+
+## Problem
+
+The current authentication mechanism is imperative and VS Code-specific:
+
+1. The renderer discovers agents via `listAgents()` and checks `IAgentDescriptor.requiresAuth`.
+2. It obtains a GitHub OAuth token from VS Code's built-in authentication service.
+3. It pushes the token via `setAuthToken(token)` — a fire-and-forget JSON-RPC notification.
+4. The agent host fans the token out to all registered `IAgent` providers.
+
+This couples the agent host to VS Code internals. An external client (CLI tool, web app, another editor) connecting over WebSocket has no way to know _what_ authentication is required, _where_ to get a token, or _what scopes_ are needed. The client must have out-of-band knowledge that "this server needs a GitHub OAuth token."
+
+## Design Goals
+
+- **Self-describing**: The server declares its auth requirements so arbitrary clients can discover them without prior knowledge of the server's internals.
+- **Standards-aligned**: Use the semantics and vocabulary of RFC 6750 (Bearer Token Usage) and RFC 9728 (OAuth 2.0 Protected Resource Metadata) adapted for JSON-RPC.
+- **Challenge-on-failure**: When auth is missing or invalid, the server responds with a structured challenge (like `WWW-Authenticate`) that tells the client exactly what to do.
+- **Transport-agnostic**: Works over WebSocket JSON-RPC and MessagePort IPC alike.
+- **Multi-provider**: Supports multiple independent auth requirements (e.g. GitHub + a future enterprise IdP) each with their own scopes and authorization servers.
+- **Non-breaking migration**: Can coexist with `setAuthToken` during a transition period.
+
+## Relevant Standards
+
+### RFC 6750 — Bearer Token Usage
+
+Defines how bearer tokens are transmitted (`Authorization: Bearer <token>`) and how servers challenge clients when auth is missing or invalid:
+
+```
+WWW-Authenticate: Bearer realm="example",
+                         error="invalid_token",
+                         error_description="The access token expired"
+```
+
+Key error codes: `invalid_request`, `invalid_token`, `insufficient_scope`.
+
+### RFC 9728 — OAuth 2.0 Protected Resource Metadata
+
+Defines a metadata document that a protected resource publishes to describe itself:
+
+```json
+{
+  "resource": "https://resource.example.com",
+  "authorization_servers": ["https://as.example.com"],
+  "scopes_supported": ["profile", "email"],
+  "bearer_methods_supported": ["header"]
+}
+```
+
+Clients discover this metadata either via a well-known URL or via the `resource_metadata` parameter in a `WWW-Authenticate` challenge. This tells the client _where_ to get a token and _what scopes_ to request.
+
+## Proposed Design
+
+### Overview
+
+The authentication flow has three phases, mirroring the HTTP flow from RFC 9728 §5:
+
+```

+
+### Phase 1: Discovery (in `initialize` response)
+
+The `initialize` result is extended with a `resourceMetadata` field, modeled on RFC 9728 §2:
+
+```typescript
+interface IInitializeResult {
+	protocolVersion: number;
+	serverSeq: number;
+	snapshots: ISnapshot[];
+	defaultDirectory?: URI;
+
+	/** RFC 9728-style resource metadata describing auth requirements. */
+	resourceMetadata?: IResourceMetadata;
+}
+
+/**
+ * Describes the agent host as an OAuth 2.0 protected resource.
+ * Modeled on RFC 9728 (OAuth 2.0 Protected Resource Metadata).
+ */
+interface IResourceMetadata {
+	/**
+	 * Identifier for this resource (the agent host).
+	 * Analogous to RFC 9728 `resource`.
+	 */
+	resource: string;
+
+	/**
+	 * Independent auth requirements. Each entry describes one
+	 * authentication scheme the server accepts. A client must
+	 * satisfy at least one to use authenticated features.
+	 */
+	authSchemes: IAuthScheme[];
+}
+
+/**
+ * A single authentication scheme the server accepts.
+ */
+interface IAuthScheme {
+	/**
+	 * The auth scheme name. Initially only "bearer" (RFC 6750).
+	 * Future schemes (e.g. "dpop", "device_code") can be added.
+	 */
+	scheme: 'bearer';
+
+	/**
+	 * An opaque identifier for this auth requirement, used to
+	 * correlate `authenticate` calls and challenges. Allows the
+	 * server to require multiple independent tokens (e.g. one
+	 * per agent provider).
+	 *
+	 * Example: "github" for GitHub Copilot auth.
+	 */
+	id: string;
+
+	/**
+	 * Human-readable label for display in auth UIs.
+	 * Analogous to RFC 9728 `resource_name`.
+	 */
+	label: string;
+
+	/**
+	 * Authorization server issuer identifiers (RFC 8414).
+	 * Tells the client where to obtain tokens.
+	 * Analogous to RFC 9728 `authorization_servers`.
+	 *
+	 * Example: ["https://github.com/login/oauth"]
+	 */
+	authorizationServers: string[];
+
+	/**
+	 * OAuth scopes the server needs.
+	 * Analogous to RFC 9728 `scopes_supported`.
+	 *
+	 * Example: ["read:user", "user:email", "repo", "workflow"]
+	 */
+	scopesSupported?: string[];
+
+	/**
+	 * Whether this auth requirement is mandatory for any
+	 * functionality, or only for specific agents/features.
+	 */
+	required?: boolean;
+}
+```
+
+**Why in `initialize`?** RFC 9728 publishes metadata at a well-known URL. In our JSON-RPC world, the `initialize` handshake _is_ the well-known endpoint — it's the first thing every client calls, and it's already where we exchange capabilities. This avoids an extra round-trip and keeps the discovery atomic.
+
+### Phase 2: Token Delivery (`authenticate` command)
+
+Replace the fire-and-forget `setAuthToken` notification with a proper JSON-RPC **request** so the client gets confirmation:
+
+```typescript
+/**
+ * Client → Server request to authenticate.
+ * Analogous to sending `Authorization: Bearer <token>` (RFC 6750 §2.1).
+ */
+interface IAuthenticateParams {
+	/**
+	 * The auth scheme identifier from the server's resourceMetadata.
+	 * Correlates to IAuthScheme.id.
+	 */
+	schemeId: string;
+
+	/** The scheme type (initially always "bearer"). */
+	scheme: 'bearer';
+
+	/** The bearer token value (RFC 6750). */
+	token: string;
+}
+
+interface IAuthenticateResult {
+	/** Whether the token was accepted. */
+	authenticated: boolean;
+}
+```
+
+This is a **request** (not a notification) so:
+- The client knows immediately if the token was accepted or rejected.
+- The server can validate the token before returning success.
+- Errors use structured challenges (see Phase 3).
+
+The client can call `authenticate` multiple times (e.g. when a token is refreshed), and can authenticate for multiple scheme IDs independently.
+
+### Phase 3: Challenges on Failure
+
+When a command fails because authentication is missing or invalid, the server returns a JSON-RPC error with structured challenge data in the `data` field, modeled on RFC 6750 §3:
+
+```typescript
+/**
+ * JSON-RPC error data for authentication failures.
+ * Modeled on RFC 6750 WWW-Authenticate challenge parameters.
+ */
+interface IAuthChallenge {
+	/** The scheme ID that needs (re-)authentication. */
+	schemeId: string;
+
+	/** RFC 6750 §3.1 error code. */
+	error: 'invalid_request' | 'invalid_token' | 'insufficient_scope';
+
+	/** Human-readable error description (RFC 6750 §3 error_description). */
+	errorDescription?: string;
+
+	/** Required scopes, if the error is insufficient_scope (RFC 6750 §3 scope). */
+	scope?: string;
+}
+```
+
+This is returned as the `data` payload of a JSON-RPC error response:
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 5,
+  "error": {
+    "code": -32007,
+    "message": "Authentication required",
+    "data": {
+      "challenges": [
+        {
+          "schemeId": "github",
+          "error": "invalid_token",
+          "errorDescription": "The access token expired"
+        }
+      ]
+    }
+  }
+}
+```
+
+A dedicated error code (`-32007 AHP_AUTH_REQUIRED`) signals this is an auth error so clients can handle it programmatically without parsing the message string.
+
+### Phase 4: Auth State Notifications
+
+The server pushes auth state changes via notifications so clients know when auth expires or the required scopes change:
+
+```typescript
+/**
+ * Server → Client notification when auth state changes.
+ */
+interface IAuthStateNotification {
+	type: 'notify/authRequired';
+
+	/** The scheme ID whose auth state changed. */
+	schemeId: string;
+
+	/** The new state. */
+	state: 'authenticated' | 'expired' | 'revoked' | 'required';
+
+	/** Optional challenge with details (e.g. new scopes needed). */
+	challenge?: IAuthChallenge;
+}
+```
+
+This replaces the implicit "push a token whenever you see an account change" model with an explicit server-driven signal.
+
+## Concrete Example: GitHub Copilot Auth
+
+### Server-side (CopilotAgent)
+
+When the Copilot agent registers, it publishes an auth scheme:
+
+```typescript
+// In CopilotAgent.getAuthSchemes():
+[{
+	scheme: 'bearer',
+	id: 'github',
+	label: 'GitHub',
+	authorizationServers: ['https://github.com/login/oauth'],
+	scopesSupported: ['read:user', 'user:email'],
+	required: true,
+}]
+```
+
+The agent host aggregates auth schemes from all agents into `IInitializeResult.resourceMetadata`.
+
+### Client-side (VS Code renderer)
+
+```typescript
+// After initialize:
+const metadata = initResult.resourceMetadata;
+if (metadata) {
+	for (const scheme of metadata.authSchemes) {
+		if (scheme.scheme === 'bearer' && scheme.authorizationServers.some(
+			as => as.includes('github.com')
+		)) {
+			// We know how to handle GitHub auth
+			const token = await this._getGitHubToken(scheme.scopesSupported);
+			await agentHostService.authenticate({
+				schemeId: scheme.id,
+				scheme: 'bearer',
+				token,
+			});
+		}
+	}
+}
+```
+
+### Client-side (generic external client)
+
+A CLI tool connecting over WebSocket:
+
+```typescript
+const ws = new WebSocket('ws://localhost:3000');
+const initResult = await rpc.request('initialize', { protocolVersion: 1, clientId: 'cli-1' });
+
+for (const scheme of initResult.resourceMetadata?.authSchemes ?? []) {
+	if (scheme.scheme === 'bearer') {
+		console.log(`Auth required: ${scheme.label}`);
+		console.log(`Get a token from: ${scheme.authorizationServers[0]}`);
+		console.log(`Scopes: ${scheme.scopesSupported?.join(', ')}`);
+
+		// Client can use any OAuth library to get the token
+		const token = await doOAuthFlow(scheme.authorizationServers[0], scheme.scopesSupported);
+		await rpc.request('authenticate', { schemeId: scheme.id, scheme: 'bearer', token });
+	}
+}
+```
+
+## Protocol Changes Summary
+
+### New JSON-RPC request: `authenticate`
+
+| Direction | Type | Params | Result |
+|---|---|---|---|
+| Client → Server | Request | `IAuthenticateParams` | `IAuthenticateResult` |
+
+### New JSON-RPC error code
+

+| `-32007` | `AHP_AUTH_REQUIRED` | A command failed because auth is missing or invalid |
+
+### Extended: `initialize` result
+
+| Field | Type | Description |
+|---|---|---|
+| `resourceMetadata` | `IResourceMetadata` | Optional. Auth and resource information. |
+
+### New notification
+
+| Type | Direction | When |
+|---|---|---|
+| `notify/authRequired` | Server → Client | Auth state changed (expired, revoked, new requirements) |
+
+### Deprecated
+
+| Item | Replacement | Migration |
+|---|---|---|
+| `setAuthToken` notification | `authenticate` request | Keep accepting `setAuthToken` for one version, log deprecation |
+| `IAgentDescriptor.requiresAuth` | `IResourceMetadata.authSchemes` | Derive from `authSchemes` during transition |
+
+## Interface Changes in `agentService.ts`
+
+### `IAgentService`
+
+```diff
+  interface IAgentService {
+-   setAuthToken(token: string): Promise<void>;
++   authenticate(params: IAuthenticateParams): Promise<IAuthenticateResult>;
+  }
+```
+
+### `IAgent`
+
+```diff
+  interface IAgent {
+-   setAuthToken(token: string): Promise<void>;
++   /** Declare auth schemes this agent requires. */
++   getAuthSchemes(): IAuthScheme[];
++   /** Authenticate with a specific scheme. Returns true if accepted. */
++   authenticate(schemeId: string, token: string): Promise<boolean>;
+  }
+```
+
+### `IAgentDescriptor`
+
+```diff
+  interface IAgentDescriptor {
+    readonly provider: AgentProvider;
+    readonly displayName: string;
+    readonly description: string;
+-   readonly requiresAuth: boolean;
+  }
+```
+
+`requiresAuth` is removed — clients discover auth requirements from `IResourceMetadata` instead of per-agent descriptors.
+
+## Design Decisions
+
+### Why not `WWW-Authenticate` headers literally?
+
+We're not using HTTP. Embedding RFC 6750's string-encoded header format in JSON-RPC would be awkward. Instead, we use JSON-native equivalents with the same semantics: `IAuthChallenge` mirrors the `WWW-Authenticate` parameters, and `IResourceMetadata` mirrors RFC 9728's metadata document.
+
+### Why in `initialize` and not a separate `getResourceMetadata` command?
+
+Fewer round-trips. Every client calls `initialize` first — embedding auth requirements there means the client knows what auth is needed from the very first response. A separate command would add latency and complexity for zero benefit, since the metadata is small and always needed.
+
+### Why `schemeId` and not just the `scheme` name?
+
+A server might need multiple bearer tokens from different authorization servers (e.g. GitHub + an enterprise IdP). The `schemeId` lets the client and server correlate tokens to specific requirements. It also makes `authenticate` calls idempotent and unambiguous.
+
+### Why a request instead of a notification for `authenticate`?
+
+The current `setAuthToken` is fire-and-forget — the client has no idea if the token was accepted, expired, or for the wrong provider. Making `authenticate` a request with a response lets the client react immediately (retry with different scopes, prompt the user, etc.).
+
+### What about Device Code / OAuth flows that the server drives?
+
+This proposal covers the "client already has a token" case (RFC 6750 bearer). For server-driven flows (device code, authorization code with redirect), the `authorizationServers` metadata tells the client which AS to talk to. The actual OAuth flow is client-side — the server just declares requirements.
+
+A future extension could add an `IAuthScheme` with `scheme: 'device_code'` that includes a device authorization endpoint, letting the server guide the client through a device flow. This is out of scope for the initial implementation.
+
+## Migration Plan
+
+1. **Phase A**: Add `resourceMetadata` to `IInitializeResult` and the `authenticate` command. Keep `setAuthToken` working as-is.
+2. **Phase B**: Update VS Code renderer to use `authenticate` instead of `setAuthToken`. External clients can start using the new flow.
+3. **Phase C**: Remove `setAuthToken`, `requiresAuth`, and the old imperative push model. Bump protocol version.
+
+## Open Questions
+
+1. **Token validation**: Should the server validate tokens eagerly on `authenticate` (e.g. call a GitHub API endpoint), or defer validation to when a command actually needs it? Eager validation gives better error messages; deferred is simpler and avoids extra network calls.
+
+2. **Per-agent vs. global auth**: The current design has one `resourceMetadata` for the whole server. Should auth schemes be per-agent-provider instead? Per-agent gives finer control (e.g. "Copilot needs GitHub, MockAgent needs nothing") but complicates the protocol. The current proposal uses global metadata with `schemeId` correlation, which the server can internally route to the right agent.
+
+3. **Token refresh**: Should the server expose token expiry information so clients can proactively refresh, or rely on `notify/authRequired` to signal when a refresh is needed? Proactive refresh avoids interruptions but requires the server to parse tokens (which it shouldn't have to for opaque tokens).
+
+4. **Multiple tokens**: Can a client authenticate multiple scheme IDs simultaneously? (Proposed: yes.) Can multiple clients each send their own token? (Proposed: yes, last-writer-wins per schemeId, which matches current behavior.)

-## Service Alignment (Required)
+Sessions-specific overrides:
 
-AI customizations must lean on existing VS Code services with well-defined interfaces. This avoids duplicated parsing logic, keeps discovery consistent across the workbench, and ensures prompt/hook behavior stays authoritative.

-Browser compatibility is required. Do not use Node.js APIs; rely on VS Code services that work in browser contexts.
+### IAICustomizationWorkspaceService
 
-Key services to rely on:
-- Prompt discovery, parsing, and lifecycle: [src/vs/workbench/contrib/chat/common/promptSyntax/service/promptsService.ts](../workbench/contrib/chat/common/promptSyntax/service/promptsService.ts)
-- Active session scoping for worktree filtering: [src/vs/workbench/contrib/chat/browser/agentSessions/agentSessionsService.ts](../workbench/contrib/chat/browser/agentSessions/agentSessionsService.ts)
-- MCP servers and tool access: [src/vs/workbench/contrib/mcp/common/mcpService.ts](../workbench/contrib/mcp/common/mcpService.ts)
-- MCP management and gallery: [src/vs/platform/mcp/common/mcpManagement.ts](../platform/mcp/common/mcpManagement.ts)
-- Chat models and session state: [src/vs/workbench/contrib/chat/common/chatService/chatService.ts](../workbench/contrib/chat/common/chatService/chatService.ts)
-- File and model plumbing: [src/vs/platform/files/common/files.ts](../platform/files/common/files.ts), [src/vs/editor/common/services/resolverService.ts](../editor/common/services/resolverService.ts)
+The `IAICustomizationWorkspaceService` interface controls per-window behavior:
 
-The active worktree comes from `IActiveSessionService` and is the source of truth for any workspace/worktree scoping.
+| Property / Method | Core VS Code | Agent Sessions Window |
+|----------|-------------|----------|
+| `managementSections` | All sections except Models | All sections except Models |
+| `getStorageSourceFilter(type)` | Delegates to `ICustomizationHarnessService` | Delegates to `ICustomizationHarnessService` |
+| `isSessionsWindow` | `false` | `true` |
+| `activeProjectRoot` | First workspace folder | Active session worktree |
 
-In the agentic workbench, prompt discovery is scoped by an agentic prompt service override that uses the active session root for workspace folders. See [src/vs/sessions/contrib/chat/browser/promptsService.ts](contrib/chat/browser/promptsService.ts).
+### ICustomizationHarnessService
 
-## Implemented Experience
+A harness represents the AI execution environment that consumes customizations.
+Storage answers "where did this come from?"; harness answers "who consumes it?".
 
-### Management Editor (Current)
+The service is defined in `common/customizationHarnessService.ts` which also provides:
+- **`CustomizationHarnessServiceBase`** — reusable base class handling active-harness state, the observable list, and `getStorageSourceFilter` dispatch.
+- **`ISectionOverride`** — per-section UI customization: `commandId` (command invocation), `rootFile` + `label` (root-file creation), `typeLabel` (custom type name), `fileExtension` (override default), `rootFileShortcuts` (dropdown shortcuts).
+- **Factory functions** — `createVSCodeHarnessDescriptor`, `createCliHarnessDescriptor`, `createClaudeHarnessDescriptor`. The VS Code harness receives `[PromptsStorage.extension, BUILTIN_STORAGE]` as extras; CLI and Claude in core receive `[]` (no extension source). Sessions CLI receives `[BUILTIN_STORAGE]`.
+- **Well-known root helpers** — `getCliUserRoots(userHome)` and `getClaudeUserRoots(userHome)` centralize the `~/.copilot`, `~/.claude`, `~/.agents` path knowledge.
+- **Filter helpers** — `matchesWorkspaceSubpath()` for segment-safe subpath matching; `matchesInstructionFileFilter()` for filename/path-prefix pattern matching.
 
-- A singleton editor surfaces Agents, Skills, Instructions, Prompts, Hooks, MCP Servers, and Models.
-- Prompts-based sections use a grouped list (Worktree/User/Extensions) with search, context menus, and an embedded editor.
-- Embedded editor uses a full `CodeEditorWidget` and auto-commits worktree files on exit (agent session workflow).
-- Creation supports manual or AI-guided flows; AI-guided creation opens a new chat with hidden system instructions.
+Available harnesses:
 
-### Tree View (Current)
+| Harness | Label | Description |
+|---------|-------|-------------|
+| `vscode` | Local | Shows all storage sources (default in core) |
+| `cli` | Copilot CLI | Restricts user roots to `~/.copilot`, `~/.claude`, `~/.agents` |
+| `claude` | Claude | Restricts user roots to `~/.claude`; hides Prompts + Plugins sections |
 
-- Unified sidebar tree with Type -> Storage -> File hierarchy.
-- Auto-expands categories to reveal storage groups.
-- Context menus provide Open and Run Prompt.
-- Creation actions are centralized in the management editor.
+In core VS Code, all three harnesses are registered but CLI and Claude only appear when their respective agents are registered (`requiredAgentId` checked via `IChatAgentService`). VS Code is the default.
+In sessions, only CLI is registered (single harness, toggle bar hidden).
 
-### Additional Surfaces (Current)
+### IHarnessDescriptor
 
-- Overview view provides counts and deep-links into the management editor.
-- Management list groups by storage with empty states, git status, and path copy actions.
+Key properties on the harness descriptor:
 
----
+| Property | Purpose |
+|----------|--------|
+| `hiddenSections` | Sidebar sections to hide (e.g. Claude: `[Prompts, Plugins]`) |
+| `workspaceSubpaths` | Restrict file creation/display to directories (e.g. Claude: `['.claude']`) |
+| `hideGenerateButton` | Replace "Generate X" sparkle button with "New X" |
+| `sectionOverrides` | Per-section `ISectionOverride` map for button behavior |
+| `requiredAgentId` | Agent ID that must be registered for harness to appear |
+| `instructionFileFilter` | Filename/path patterns to filter instruction items |
 
-## AI Feature Gating
+### IStorageSourceFilter
 
-All commands and UI must respect `ChatContextKeys.enabled`:
+A unified per-type filter controlling which storage sources and user file roots are visible.
+Replaces the old `visibleStorageSources`, `getVisibleStorageSources(type)`, and `excludedUserFileRoots`.
 
 ```typescript
-All entry points (view contributions, commands) respect `ChatContextKeys.enabled`.
+interface IStorageSourceFilter {
+  sources: readonly PromptsStorage[];         // Which storage groups to display
+  includedUserFileRoots?: readonly URI[];     // Allowlist for user roots (undefined = all)
+}
 ```
 
----
+The shared `applyStorageSourceFilter()` helper applies this filter to any `{uri, storage}` array.
+
+**Sessions filter behavior (CLI harness):**
+
+| Type | sources | includedUserFileRoots |
+|------|---------|----------------------|
+| Hooks | `[local, plugin]` | N/A |
+| Prompts | `[local, user, plugin, builtin]` | `undefined` (all roots) |
+| Agents, Skills, Instructions | `[local, user, plugin, builtin]` | `[~/.copilot, ~/.claude, ~/.agents]` |
+
+**Core VS Code filter behavior:**
+
+Local harness: all types use `[local, user, extension, plugin, builtin]` with no user root filter. Items from the default chat extension (`productService.defaultChatAgent.chatExtensionId`) are grouped under "Built-in" via `groupKey` override in the list widget.
+
+CLI harness (core):
+
+| Type | sources | includedUserFileRoots |
+|------|---------|----------------------|
+| Hooks | `[local, plugin]` | N/A |
+| Prompts | `[local, user, plugin]` | `undefined` (all roots) |
+| Agents, Skills, Instructions | `[local, user, plugin]` | `[~/.copilot, ~/.claude, ~/.agents]` |
+
+Claude harness (core):
+
+| Type | sources | includedUserFileRoots |
+|------|---------|----------------------|
+| Hooks | `[local, plugin]` | N/A |
+| Prompts | `[local, user, plugin]` | `undefined` (all roots) |
+| Agents, Skills, Instructions | `[local, user, plugin]` | `[~/.claude]` |
+
+Claude additionally applies:
+- `hiddenSections: [Prompts, Plugins]`
+- `instructionFileFilter: ['CLAUDE.md', 'CLAUDE.local.md', '.claude/rules/', 'copilot-instructions.md']`
+- `workspaceSubpaths: ['.claude']` (instruction files matching `instructionFileFilter` are exempt)
+- `sectionOverrides`: Hooks → `copilot.claude.hooks` command; Instructions → "Add CLAUDE.md" primary, "Rule" type label, `.md` file extension
+
+### Built-in Extension Grouping (Core VS Code)
+
+In core VS Code, customization items contributed by the default chat extension (`productService.defaultChatAgent.chatExtensionId`, typically `GitHub.copilot-chat`) are grouped under the "Built-in" header in the management editor list widget, separate from third-party "Extensions".
+
+This follows the same pattern as the MCP list widget, which determines grouping at the UI layer by inspecting collection sources. The list widget uses `IProductService` to identify the chat extension and sets `groupKey: BUILTIN_STORAGE` on matching items:
+
+- **Agents**: checks `agent.source.extensionId` against the chat extension ID
+- **Skills**: builds a URI→ExtensionIdentifier lookup from `listPromptFiles(PromptsType.skill)`, then checks each skill's URI
+- **Prompts**: checks `command.promptPath.extension?.identifier`
+- **Instructions/Hooks**: checks `item.extension?.identifier` via `IPromptPath`
+
+The underlying `storage` remains `PromptsStorage.extension` — the grouping is a UI-level override via `groupKey` that keeps `applyStorageSourceFilter` working with existing storage types while visually distinguishing chat-extension items from third-party extension items.
+
+`BUILTIN_STORAGE` is defined in `aiCustomizationWorkspaceService.ts` (common layer) and re-exported by both `aiCustomizationManagement.ts` (browser) and `builtinPromptsStorage.ts` (sessions) for backward compatibility.
+
+### AgenticPromptsService (Sessions)
+
+Sessions overrides `PromptsService` via `AgenticPromptsService` (in `promptsService.ts`):
+
+- **Discovery**: `AgenticPromptFilesLocator` scopes workspace folders to the active session's worktree
+- **Built-in skills**: Discovers bundled `SKILL.md` files from `vs/sessions/skills/{name}/` and surfaces them with `PromptsStorage.builtin` storage type
+- **User override**: Built-in skills are omitted when a user or workspace skill with the same name exists
+- **Creation targets**: `getSourceFolders()` override replaces VS Code profile user roots with `~/.copilot/{subfolder}` for CLI compatibility
+- **Hook folders**: Falls back to `.github/hooks` in the active worktree
+
+### Built-in Skills
+
+All built-in customizations bundled with the Sessions app are skills, living in `src/vs/sessions/skills/{name}/SKILL.md`. They are:
+
+- Discovered at runtime via `FileAccess.asFileUri('vs/sessions/skills')`
+- Tagged with `PromptsStorage.builtin` storage type
+- Shown in a "Built-in" group in the AI Customization tree view and management editor
+- Filtered out when a user/workspace skill shares the same name (override behavior)
+- Skills with UI integrations (e.g. `act-on-feedback`, `generate-run-commands`) display a "UI Integration" badge in the management editor
+
+### UI Integration Badges
+
+Skills that are directly invoked by UI elements (toolbar buttons, menu items) are annotated with a "UI Integration" badge in the management editor. The mapping is provided by `IAICustomizationWorkspaceService.getSkillUIIntegrations()`, which the Sessions implementation populates with the relevant skill names and tooltip descriptions. The badge appears on both the built-in skill and any user/workspace override, ensuring users understand that overriding the skill affects a UI surface.
+
+### Count Consistency
+
+`customizationCounts.ts` uses the **same data sources** as the list widget's `loadItems()`:
+
+| Type | Data Source | Notes |
+|------|-------------|-------|
+| Agents | `getCustomAgents()` | Parsed agents, not raw files |
+| Skills | `findAgentSkills()` | Parsed skills with frontmatter |
+| Prompts | `getPromptSlashCommands()` | Filters out skill-type commands |
+| Instructions | `listPromptFiles()` + `listAgentInstructions()` | Includes AGENTS.md, CLAUDE.md etc. |
+| Hooks | `listPromptFiles()` | Individual hooks parsed via `parseHooksFromFile()` |
+
+### Item Badges
+
+`IAICustomizationListItem.badge` is an optional string that renders as a small inline tag next to the item name (same visual style as the MCP "Bridged" badge). For context instructions, this badge shows the raw `applyTo` pattern (e.g. a glob like `**/*.ts`), while the tooltip (`badgeTooltip`) explains the behavior. For skills with UI integrations, the badge reads "UI Integration" with a tooltip describing which UI surface invokes the skill. The badge text is also included in search filtering.
+
+### Debug Panel
+
+Toggle via Command Palette: "Toggle Customizations Debug Panel". Shows a 4-stage pipeline view:
+
+1. **Raw PromptsService data** — per-storage file lists + type-specific extras
+2. **After applyStorageSourceFilter** — what was removed and why
+3. **Widget state** — allItems vs displayEntries with group counts
+4. **Source/resolved folders** — creation targets and discovery order
+
+## Key Services
+
+- **Prompt discovery**: `IPromptsService` — parsing, lifecycle, storage enumeration
+- **MCP servers**: `IMcpService` — server list, tool access
+- **Active worktree**: `IActiveSessionService` — source of truth for workspace scoping (sessions only)
+- **File operations**: `IFileService`, `ITextModelService` — file and model plumbing
+
+Browser compatibility is required — no Node.js APIs.
+
+## Feature Gating
+
+All commands and UI respect `ChatContextKeys.enabled` and the `chat.customizationsMenu.enabled` setting.
+
+## Settings

+### Core Concepts
+
+#### Session Type (`ISessionType`)
+
+A lightweight label identifying an agent backend. Says nothing about where it runs or how it's configured.
+
+```typescript
+// Platform-level session type (registered once)
+interface ISessionType {
+    readonly id: string;      // e.g., 'copilot-cli', 'copilot-cloud'
+    readonly label: string;   // e.g., 'Copilot CLI', 'Cloud'
+    readonly icon: ThemeIcon;
+}
+```
+
+#### Sessions Provider (`ISessionsProvider`)
+
+A compute environment adapter. One provider can serve multiple session types. Multiple provider instances can serve the same session type.
+
+```typescript
+interface ISessionsProvider {
+    readonly id: string;                       // 'default-copilot', 'agenthost-hostA'
+    readonly label: string;
+    readonly sessionTypes: readonly ISessionType[];
+
+    // Workspace browsing
+    getWorkspaces(): ISessionWorkspace[];
+    readonly browseActions: readonly ISessionsBrowseAction[];
+
+    // Session CRUD
+    getSessions(): ISessionData[];
+    createNewSession(workspace: ISessionWorkspace): ISessionData;
+    sendRequest(sessionId: string, options: ISendRequestOptions): Promise<ISessionData>;
+
+    // Lifecycle
+    archiveSession(sessionId: string): Promise<void>;
+    deleteSession(sessionId: string): Promise<void>;
+    renameSession(sessionId: string, title: string): Promise<void>;
+}
+```
+
+#### Session Data (`ISessionData`)
+
+The universal session interface. All reactive properties are observables — UI components subscribe and update automatically.
+
+```typescript
+interface ISessionData {
+    readonly sessionId: string;          // Globally unique: 'providerId:localId'
+    readonly resource: URI;
+    readonly providerId: string;
+    readonly sessionType: string;        // e.g., 'copilot-cli'
+
+    // Reactive properties
+    readonly title: IObservable<string>;
+    readonly status: IObservable<SessionStatus>;
+    readonly workspace: IObservable<ISessionWorkspace | undefined>;
+    readonly changes: IObservable<readonly IChatSessionFileChange[]>;
+    readonly isArchived: IObservable<boolean>;
+    readonly isRead: IObservable<boolean>;
+    readonly lastTurnEnd: IObservable<Date | undefined>;
+}
+```
+
+### Examples
+
+#### Example 1: CopilotChatSessionsProvider
+
+The default provider wrapping existing CLI and Cloud sessions:
+
+```
+CopilotChatSessionsProvider
+├── id: 'default-copilot'
+├── sessionTypes: [CopilotCLI, CopilotCloud]
+├── browseActions:
+│   ├── "Browse Folders..." → file dialog
+│   └── "Browse Repositories..." → GitHub repo picker
+├── getSessions() → wraps IAgentSession[] as AgentSessionAdapter[]
+├── createNewSession(workspace)
+│   ├── file:// URI → CopilotCLISession (local background agent)
+│   └── github-remote-file:// → RemoteNewSession (cloud agent)
+└── sendRequest() → delegates to IChatService
+```
+
+#### Example 2: RemoteAgentHostSessionsProvider
+
+One instance per connected remote agent host:
+
+```
+RemoteAgentHostSessionsProvider
+├── id: 'agenthost-<hostId>'
+├── sessionTypes: [CopilotCLI]  (reuses platform type)
+├── browseActions:
+│   └── "Browse Remote Folders..." → remote folder picker
+├── getSessions() → sessions from this specific host
+└── createNewSession(workspace)
+    └── Creates session on the remote agent host
+```
+
+### Data Flow
+
+#### Creating a New Session
+
+```
+User picks workspace in WorkspacePicker
+    │
+    ▼
+SessionsManagementService.createNewSession(providerId, workspace)
+    │
+    ├── Finds provider by ID

+# Sessions Provider Architecture
+
+## Overview
+
+The Sessions Provider architecture introduces an **extensible provider model** for managing agent sessions in the Agent Sessions window. Instead of hardcoding session types and backends, multiple providers register with a central registry (`ISessionsProvidersService`), which aggregates sessions from all providers and routes actions to the correct one.
+
+This design allows new compute environments (remote agent hosts, cloud backends, third-party agents) to plug in without modifying core session management code.

+
+## Core Interfaces
+
+### `ISessionData` — Universal Session Facade
+
+**File:** `src/vs/sessions/contrib/sessions/common/sessionData.ts`
+
+The common session interface exposed by all providers. It is a self-contained facade — consumers should not reach back to underlying services to resolve additional data. All mutable properties are **observables** for reactive UI binding.
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `sessionId` | `string` | Globally unique ID in the format `providerId:localId` |
+| `resource` | `URI` | Resource URI identifying this session |
+| `providerId` | `string` | ID of the owning provider |
+| `sessionType` | `string` | Session type ID (e.g., `'background'`, `'cloud'`) |
+| `icon` | `ThemeIcon` | Display icon |
+| `createdAt` | `Date` | Creation timestamp |
+| `workspace` | `IObservable<ISessionWorkspace \| undefined>` | Workspace info (repositories, label, icon) |
+| `title` | `IObservable<string>` | Display title (auto-titled or renamed) |
+| `updatedAt` | `IObservable<Date>` | Last update timestamp |
+| `status` | `IObservable<SessionStatus>` | Current status (Untitled, InProgress, NeedsInput, Completed, Error) |
+| `changes` | `IObservable<readonly IChatSessionFileChange[]>` | File changes produced by the session |
+| `modelId` | `IObservable<string \| undefined>` | Selected model identifier |
+| `mode` | `IObservable<{id, kind} \| undefined>` | Selected mode identifier and kind |
+| `loading` | `IObservable<boolean>` | Whether the session is initializing |
+| `isArchived` | `IObservable<boolean>` | Archive state |
+| `isRead` | `IObservable<boolean>` | Read/unread state |
+| `description` | `IObservable<IMarkdownString \| undefined>` | Status description (e.g., current agent action), supports markdown |
+| `lastTurnEnd` | `IObservable<Date \| undefined>` | When the last agent turn ended |
+| `pullRequest` | `IObservable<ISessionPullRequest \\| undefined>` | Associated pull request |
+
+#### Supporting Types
+
+**`ISessionWorkspace`** — Workspace information for a session:
+- `label: string` — Display label (e.g., "my-app", "org/repo")
+- `icon: ThemeIcon` — Workspace icon
+- `repositories: ISessionRepository[]` — One or more repositories
+
+**`ISessionRepository`** — A repository within a workspace:
+- `uri: URI` — Source repository URI (`file://` or `github-remote-file://`)
+- `workingDirectory: URI | undefined` — Worktree or checkout path

+
+**`SessionStatus`** — Enum: `Untitled`, `InProgress`, `NeedsInput`, `Completed`, `Error`
+
+---
+
+### `ISessionsProvider` — Provider Contract
+
+**File:** `src/vs/sessions/contrib/sessions/browser/sessionsProvider.ts`
+
+A sessions provider encapsulates a compute environment. It owns workspace discovery, session creation, session listing, and picker contributions. One provider can serve multiple session types, and multiple provider instances can serve the same session type (e.g., one per remote agent host).
+
+#### Identity
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `id` | `string` | Unique provider instance ID (e.g., `'default-copilot'`, `'agenthost-hostA-copilot'`) |
+| `label` | `string` | Display label |
+| `icon` | `ThemeIcon` | Provider icon |
+| `sessionTypes` | `readonly ISessionType[]` | Session types this provider supports |
+
+#### Workspace Discovery
+
+| Member | Description |
+|--------|-------------|
+| `browseActions: readonly ISessionsBrowseAction[]` | Actions shown in the workspace picker (e.g., "Browse Folders...", "Browse Repositories...") |
+| `resolveWorkspace(repositoryUri: URI): ISessionWorkspace` | Resolve a URI to a session workspace with label and icon |
+
+#### Session Listing
+
+| Member | Description |
+|--------|-------------|
+| `getSessions(): ISessionData[]` | Returns all sessions owned by this provider |
+| `onDidChangeSessions: Event<ISessionsChangeEvent>` | Fires when sessions are added, removed, or changed |
+
+#### Session Lifecycle
+
+| Method | Description |
+|--------|-------------|
+| `createNewSession(workspace)` | Create a new session for a given workspace |
+| `setSessionType(sessionId, type)` | Change the session type |
+| `getSessionTypes(session)` | Get available session types for a session |
+| `renameSession(sessionId, title)` | Rename a session |
+| `setModel(sessionId, modelId)` | Set the model |
+| `archiveSession(sessionId)` | Archive a session |
+| `unarchiveSession(sessionId)` | Unarchive a session |
+| `deleteSession(sessionId)` | Delete a session |
+| `setRead(sessionId, read)` | Mark read/unread |
+
+#### Send
+
+| Method | Description |
+|--------|-------------|
+| `sendRequest(sessionId, options)` | Send the initial request for a new session; returns the created `ISessionData` |
+
+#### Supporting Types
+
+**`ISessionType`** — A platform-level session type identifying an agent backend:
+- `id: string` — Unique identifier (e.g., `'background'`, `'cloud'`)
+- `label: string` — Display label
+- `icon: ThemeIcon` — Icon
+- `requiresWorkspaceTrust?: boolean` — Whether workspace trust is required
+
+**`ISessionsBrowseAction`** — A browse action shown in the workspace picker:
+- `label`, `icon`, `providerId`
+- `execute(): Promise<ISessionWorkspace | undefined>` — Opens the browse dialog
+
+**`ISessionsChangeEvent`** — Change event:
+- `added: readonly ISessionData[]`
+- `removed: readonly ISessionData[]`
+- `changed: readonly ISessionData[]`
+
+**`ISendRequestOptions`** — Send request options:
+- `query: string` — Query text
+- `attachedContext?: IChatRequestVariableEntry[]` — Optional attached context entries
+
+---
+
+### `ISessionsProvidersService` — Central Registry & Aggregator
+
+**File:** `src/vs/sessions/contrib/sessions/browser/sessionsProvidersService.ts`
+
+Central service that aggregates sessions across all registered providers. Owns the provider registry, unified session list, and routes session actions to the correct provider.
+
+#### Provider Registry
+
+| Member | Description |
+|--------|-------------|
+| `registerProvider(provider): IDisposable` | Register a provider; returns disposable to unregister |
+| `getProviders(): ISessionsProvider[]` | Get all registered providers |
+| `onDidChangeProviders: Event<void>` | Fires when providers are added or removed |
+
+#### Session Types
+
+| Member | Description |
+|--------|-------------|
+| `getSessionTypesForProvider(providerId)` | Get session types from a specific provider |
+| `getSessionTypes(session)` | Get session types available for a session |
+
+#### Aggregated Sessions
+
+| Member | Description |
+|--------|-------------|
+| `getSessions(): ISessionData[]` | Get all sessions from all providers |
+| `getSession(sessionId): ISessionData \| undefined` | Look up a session by its globally unique ID |
+| `onDidChangeSessions: Event<ISessionsChangeEvent>` | Fires when sessions change across any provider |
+
+#### Routed Actions
+
+Actions are automatically routed to the correct provider by extracting the provider ID from the session ID:
+
+- `archiveSession(sessionId)`
+- `unarchiveSession(sessionId)`
+- `deleteSession(sessionId)`
+- `renameSession(sessionId, title)`
+- `setRead(sessionId, read)`
+- `resolveWorkspace(providerId, repositoryUri)`
+
+#### Session ID Format
+
+Session IDs use the format `${providerId}:${localId}`, where `providerId` identifies the owning provider and `localId` is a provider-scoped identifier (typically the session resource URI string). The separator `:` allows the registry to parse the provider ID for routing.
+
+---
+
+### `ISessionsManagementService` — High-Level Orchestration
+
+**File:** `src/vs/sessions/contrib/sessions/browser/sessionsManagementService.ts`
+
+Coordinates active session tracking, provider selection, and user workflows. Sits above the providers service and adds UI-facing concerns.
+
+#### Key Responsibilities
+
+- **Active session tracking** — `activeSession: IObservable<ISessionData | undefined>` tracks the currently selected session
+- **Provider selection** — `activeProviderId: IObservable<string | undefined>` auto-selects when one provider exists, persists to storage
+- **Context keys** — Manages `isNewChatSession`, `activeSessionProviderId`, `activeSessionType`, `isActiveSessionBackgroundProvider`
+- **Session creation** — `createNewSession(providerId, workspace)` delegates to the correct provider
+- **Send orchestration** — `sendRequest(session, options)` sends through the provider and manages state transitions
+- **GitHub context** — `getGitHubContext(session)` derives owner/repo/PR info from session metadata
+- **File resolution** — `resolveSessionFileUri(sessionResource, relativePath)` resolves file paths within session worktrees
+
+---
+
+## Provider Implementations
+
+### `CopilotChatSessionsProvider` — Default Copilot Provider
+
+**File:** `src/vs/sessions/contrib/copilotChatSessions/browser/copilotChatSessionsProvider.ts`
+
+The default sessions provider, registered with ID `'default-copilot'`. Wraps the existing agent session infrastructure into the extensible provider model. Supports two session types: **Copilot CLI** (local) and **Copilot Cloud** (remote).
+
+#### Registration
+
+Registered via `DefaultSessionsProviderContribution` workbench contribution at `WorkbenchPhase.AfterRestored`:
+
+```
+src/vs/sessions/contrib/copilotChatSessions/browser/copilotChatSessions.contribution.ts
+```
+
+```typescript
+class DefaultSessionsProviderContribution extends Disposable {
+    constructor(instantiationService, sessionsProvidersService) {
+        const provider = instantiationService.createInstance(CopilotChatSessionsProvider);
+        sessionsProvidersService.registerProvider(provider);
+    }
+}
+```
+
+#### Identity
+
+| Property | Value |
+|----------|-------|
+| `id` | `'default-copilot'` |
+| `label` | `'Copilot Chat'` |
+| `icon` | `Codicon.copilot` |
+| `sessionTypes` | `[CopilotCLISessionType, CopilotCloudSessionType]` |
+
+#### Browse Actions
+
+- **"Browse Folders..."** — Opens a folder dialog; creates a workspace with a `file://` URI
+- **"Browse Repositories..."** — Executes `github.copilot.chat.cloudSessions.openRepository`; creates a workspace with a `github-remote-file://` URI
+
+#### New Session Classes
+
+When `createNewSession(workspace)` is called, the provider creates one of two concrete `ISessionData` implementations based on the workspace URI scheme:
+
+**`CopilotCLISession`** — For local `file://` workspaces:
+- Implements `ISessionData` plus provider-specific observable fields (`permissionLevel`, `branchObservable`, `isolationModeObservable`)
+- Performs async git repository resolution during construction (sets `loading` to true until resolved)
+- Configuration methods: `setIsolationMode()`, `setBranch()`, `setModelId()`, `setMode()`, `setPermissionLevel()`, `setModeById()`
+- Tracks selected options via `Map<string, IChatSessionProviderOptionItem>` and syncs to `IChatSessionsService`
+- Uses `IGitService` to open the repository and resolve branch information
+
+**`RemoteNewSession`** — For cloud `github-remote-file://` workspaces:
+- Implements `ISessionData`
+- Manages dynamic option groups from `IChatSessionsService.getOptionGroupsForSessionType()` with `when` clause visibility
+- No-ops for isolation/branch/client mode (cloud-managed)
+- Provides `getModelOptionGroup()`, `getOtherOptionGroups()` for UI to render provider-specific pickers
+- Watches context key changes to dynamically show/hide option groups
+
+#### `AgentSessionAdapter` — Wrapping Existing Sessions
+
+Adapts an existing `IAgentSession` from the chat layer into the `ISessionData` facade:
+- Constructs with initial values from the agent session's metadata and timing
+- `update(session)` performs a batched observable transaction to update all reactive properties
+- Extracts workspace info, changes, description, and PR URI from session metadata
+- Maps `ChatSessionStatus` → `SessionStatus`
+- Handles both CLI and Cloud session metadata formats for repository resolution
+
+#### Session Cache & Change Events
+
+The provider maintains a `Map<string, AgentSessionAdapter>` cache keyed by resource URI:
+- `_ensureSessionCache()` performs lazy initialization
+- `_refreshSessionCache()` diffs current `IAgentSession` list against the cache, producing `added`, `removed`, and `changed` arrays
+- Changed adapters are updated in-place via `adapter.update(session)`
+- Change events are forwarded through `onDidChangeSessions`
+
+#### Send Flow
+
+1. Validate the session is a current new session (`CopilotCLISession` or `RemoteNewSession`)
+2. Resolve mode, permission level, and send options from session configuration
+3. Get or create a chat session via `IChatSessionsService`
+4. Open the chat widget via `IChatWidgetService.openSession()`
+5. Load the session model and apply selected model, mode, and options
+6. Send the request via `IChatService.sendRequest()`
+7. Wait for a new `IAgentSession` to appear in `IAgentSessionsService.model.sessions`
+8. Wrap the new agent session as `AgentSessionAdapter` and return it
+9. Clear the current new session reference
+
+---
+
+### `RemoteAgentHostSessionsProvider` — Remote Agent Host Provider
+
+**File:** `src/vs/sessions/contrib/remoteAgentHost/browser/remoteAgentHostSessionsProvider.ts`
+
+A sessions provider for a single agent on a remote agent host connection. One instance is created per agent discovered on each connection.
+
+#### Registration
+
+Registered dynamically by `RemoteAgentHostContribution`:
+
+```
+src/vs/sessions/contrib/remoteAgentHost/browser/remoteAgentHost.contribution.ts
+```
+
+- Monitors `IRemoteAgentHostService.onDidChangeConnections`
+- Creates one `RemoteAgentHostSessionsProvider` per agent per connection
+- Registers via `sessionsProvidersService.registerProvider(sessionsProvider)` into a per-agent `DisposableStore`
+- Disposes providers when connections are removed
+
+#### Identity
+
+| Property | Format |
+|----------|--------|
+| `id` | `'agenthost-${sanitizedAuthority}-${agentProvider}'` |
+| `label` | Connection name or `'${agentProvider} (${address})'` |
+| `icon` | `Codicon.remote` |
+| `sessionTypes` | `[CopilotCLISessionType]` (reuses the platform type) |
+
+#### Browse Actions
+
+- **"Browse Remote Folders..."** — Opens a file dialog scoped to the agent host filesystem (`agent-host://` scheme)
+
+#### New Session Behavior
+
+`createNewSession(workspace)` creates a minimal `ISessionData` object literal (not a class instance) with:
+- All observable fields initialized via `observableValue()`
+- Status set to `SessionStatus.Untitled`
+- Workspace label derived from the URI path
+
+#### Stubbed Operations
+
+Most session actions are no-ops because session lifecycle is managed by the existing `AgentHostSessionHandler` and `AgentHostSessionListController`, which are registered separately by the contribution:
+- `archiveSession` / `unarchiveSession` / `deleteSession` / `renameSession` / `setRead` — no-op
+- `sendRequest` — throws (handled by the session handler)
+- `getSessions()` — returns empty array (managed by the list controller)
+
+---
+
+## Data Flow: Session Lifecycle
+
+### Creating a New Session
+
+```
+1. User picks a workspace in the workspace picker
+   → SessionsManagementService.createNewSession(providerId, workspace)
+   → Looks up provider by ID in SessionsProvidersService
+   → Calls provider.createNewSession(workspace)
+   → Provider creates CopilotCLISession (file://) or RemoteNewSession (github-remote-file://)
+   → Returns ISessionData, sets as activeSession observable
+
+2. User configures session (model, isolation mode, branch)
+   → Modifies observable fields on the new session object
+   → Selections synced to IChatSessionsService via setOption()
+
+3. User types a message and sends
+   → SessionsManagementService.sendRequest(session, {query, attachedContext})
+   → Delegates to provider.sendRequest(sessionId, options)
+   → Provider opens chat widget, applies config, sends through IChatService
+   → Waits for IAgentSession to appear in the model
+   → Wraps as AgentSessionAdapter, caches it
+   → Returns new ISessionData
+   → isNewChatSession context → false
+```
+
+### Session Change Propagation
+
+```
+Agent session state changes (turn complete, status update, etc.)
+  → AgentSessionsService.model.onDidChangeSessions
+  → CopilotChatSessionsProvider._refreshSessionCache()
+    - Diffs current IAgentSession list vs cache
+    - Updates existing AgentSessionAdapter observables
+    - Creates/removes entries as needed
+    - Fires onDidChangeSessions { added, removed, changed }
+  → SessionsProvidersService forwards the event
+  → SessionsManagementService forwards and updates active session
+  → UI re-renders via observable subscriptions
+```
+
+### Session ID Routing
+
+When the management service or UI invokes an action (e.g., `archiveSession`):
+
+```
+sessionId = "default-copilot:background:///untitled-abc123"
+           ├──────────────┤ ├──────────────────────────────┤
+            provider ID      local ID (resource URI string)
+
+SessionsProvidersService._resolveProvider(sessionId)
+  → Splits at first ':'
+  → Looks up provider 'default-copilot' in the registry
+  → Delegates to provider.archiveSession(sessionId)
+```
+
+---
+
+## Context Keys
+
+| Context Key | Type | Description |
+|-------------|------|-------------|
+| `isNewChatSession` | `boolean` | `true` when viewing the new-session form (no established session selected) |
+| `activeSessionProviderId` | `string` | Provider ID of the active session (e.g., `'default-copilot'`) |
+| `activeSessionType` | `string` | Session type of the active session (e.g., `'background'`, `'cloud'`) |
+| `isActiveSessionBackgroundProvider` | `boolean` | Whether the active session uses the background agent provider |
+
+---
+
+## Adding a New Provider
+
+To add a new sessions provider:
+
+1. **Implement `ISessionsProvider`** with a unique `id`, supported `sessionTypes`, and `browseActions`
+2. **Create session data classes** implementing `ISessionData` with observable properties for the new session type
+3. **Register via a workbench contribution** at `WorkbenchPhase.AfterRestored`:
+   ```typescript
+   class MyProviderContribution extends Disposable implements IWorkbenchContribution {
+       constructor(
+           @IInstantiationService instantiationService: IInstantiationService,
+           @ISessionsProvidersService sessionsProvidersService: ISessionsProvidersService,
+       ) {
+           super();
+           const provider = this._register(instantiationService.createInstance(MyProvider));
+           this._register(sessionsProvidersService.registerProvider(provider));
+       }
+   }

+# Copilot Agent Runtime — Customization Surface Spec
+
+> **Purpose:** Definitive reference for every customization mechanism that affects agent behavior when a user sends a message. Intended for building a UI that collects all customizations into a single view.
+>
+> **Source:** `github/copilot-agent-runtime` codebase as of 2026-02-25.
+
+> Some information has been removed by the human compiling this spec, scoping to what is deemed most relevant for the agent sessions window implementation. For the full details, see the source code (for maintainers likely checked out side-by-side).
+
+---
+
+## Overview
+
+When a user sends a message, the agent assembles its behavior from **10 customization categories**, each discovered from well-known file paths, environment variables, or runtime APIs. This document enumerates every source, file pattern, and merge rule.
+
+---
+
+## 1. Instructions
+
+System-prompt additions that shape how the agent responds. Multiple sources are discovered and merged in priority order.
+
+### 1.1 Repo-Level Instruction Files
+
+Each pattern is defined in `src/helpers/repo-helpers.ts` → `instructionPatterns`:
+
+| Convention | File Pattern | Notes |
+|------------|-------------|-------|
+| Copilot | `{repo}/.github/copilot-instructions.md` | Primary repo instructions |
+| Codex / OpenAI | `{repo}/AGENTS.md` | OpenAI model convention |
+| Claude / Anthropic | `{repo}/CLAUDE.md` | Claude model convention |
+| Claude (alt) | `{repo}/.claude/CLAUDE.md` | Secondary Claude location |
+| Gemini / Google | `{repo}/GEMINI.md` | Gemini model convention |
+
+### 1.2 VSCode-Style Instruction Files
+
+Glob-matched instruction files with metadata (applyTo patterns, description).
+
+| Scope | File Pattern | Code Reference |
+|-------|-------------|----------------|
+| Repo | `{repo}/.github/instructions/**/*.instructions.md` | `readVSCodeInstructions()` |
+| User | `~/.copilot/instructions/**/*.instructions.md` | `readUserCopilotInstructions()` |
+
+### 1.3 User-Level Instructions
+
+| Scope | File Pattern | Code Reference |
+|-------|-------------|----------------|
+| User global | `~/.copilot/copilot-instructions.md` | `hasHomeCopilotInstructions()` |
+
+### 1.4 CWD-Specific Instructions
+
+When the working directory differs from the repo root, the same instruction patterns are re-checked relative to `{cwd}`:
+
+- `{cwd}/.github/copilot-instructions.md`
+- `{cwd}/CLAUDE.md`, `{cwd}/.claude/CLAUDE.md`
+- `{cwd}/AGENTS.md`
+- `{cwd}/GEMINI.md`
+
+### 1.5 Nested / Child Instructions
+
+Breadth-first traversal from `{cwd}` up to **2 levels deep** (`CHILD_INSTRUCTIONS_MAX_DEPTH = 2`), scanning all instruction patterns in subdirectories.
+
+**Ignored directories:** `node_modules`, `.git`, `vendor`, `dist`, `build`, `.next`, `.nuxt`, `out`, `coverage` (plus `.gitignore` patterns when available).
+
+Feature-gated via `enableChildInstructions` option.
+
+### 1.6 Additional Sources
+
+| Source | Mechanism |
+|--------|-----------|
+| Env var | `COPILOT_CUSTOM_INSTRUCTIONS_DIRS` — comma-separated list of additional directories to scan |
+| Organization | `RuntimeContext.organizationCustomInstructions` — injected at runtime via API (not file-based) |
+
+### 1.7 Merge Order
+
+Instructions are concatenated in this order (all additive):
+
+1. User global (`~/.copilot/copilot-instructions.md`)
+2. Repo-level instruction files (all patterns above)
+3. VSCode-style instruction files (repo, then user)
+4. CWD-specific overrides (when cwd ≠ repo root)
+5. Child/nested instructions
+6. Organization instructions (API-injected)
+
+Duplicate content is deduplicated by file content hash.
+
+---
+
+## 2. Skills
+
+Reusable prompt-based capabilities exposed as `/skill-name` slash commands.
+
+### 2.1 Discovery Paths
+
+| Source | File Pattern | Code Reference |
+|--------|-------------|----------------|
+| Repo (Copilot) | `{repo}/.github/skills/*/SKILL.md` | `loader.ts` collectProjectDirs |
+| Repo (Agents) | `{repo}/.agents/skills/*/SKILL.md` | `loader.ts` collectProjectDirs |
+| Repo (Claude) | `{repo}/.claude/skills/*/SKILL.md` | `loader.ts` collectProjectDirs |
+| User (Copilot) | `~/.copilot/skills/*/SKILL.md` | `loader.ts` personalDirs |
+| User (Claude) | `~/.claude/skills/*/SKILL.md` | `loader.ts` personalDirs |
+| Env var | Dirs listed in `COPILOT_SKILLS_DIRS` (comma-separated) | `loader.ts` |
+| Plugins | `{pluginRoot}/skills/*/SKILL.md` | `skills.ts` |
+
+### 2.2 File Structure
+
+Each skill is a directory containing a `SKILL.md` file with YAML frontmatter:
+
+```
+.github/skills/
+  my-skill/
+    SKILL.md       ← markdown with frontmatter
+```
+
+Or a flat `SKILL.md` directly in the skills directory (single-skill mode).
+
+### 2.3 Frontmatter Schema
+
+```yaml
+---
+name: skill-name                      # Optional; derived from folder name if absent
+description: "What this skill does"   # Optional; derived from first 3 lines of body
+allowed-tools: grep,view              # Comma-separated tool whitelist (optional)
+user-invocable: true                  # Whether user can invoke via slash command (default: true)
+disable-model-invocation: false       # Whether model can invoke autonomously (default: false)
+---
+
+Skill prompt content here...
+```
+
+---
+
+## 3. Commands
+
+A variant of skills, loaded from `.claude/commands/` only.
+
+| Source | File Pattern | Code Reference |
+|--------|-------------|----------------|
+| Project | `{repo}/.claude/commands/*.md` | `loader.ts` getCommandDirectories |
+| User | `~/.claude/commands/*.md` | `loader.ts` getCommandDirectories |
+
+**Note:** Commands use only the `.claude/` convention — not `.github/` or `.agents/`.
+
+Any `.md` file in the directory is treated as a command. Same frontmatter schema as skills. Treated internally as skills with `isCommand: true`. Skills take priority over commands on name conflicts.
+
+---
+
+## 4. Custom Agents
+
+Sub-agent definitions available via the task tool or direct user selection.
+
+### 4.1 Discovery Paths
+
+| Source | File Pattern | Code Reference |
+|--------|-------------|----------------|
+| Repo (Copilot) | `{repo}/.github/agents/*.md`, `*.agent.md` | `useCustomAgents.ts` |
+| Repo (Claude) | `{repo}/.claude/agents/*.md`, `*.agent.md` | `useCustomAgents.ts` |
+| User (Copilot) | `~/.github/agents/*.md`, `*.agent.md` | `useCustomAgents.ts` |
+| User (Claude) | `~/.claude/agents/*.md`, `*.agent.md` | `useCustomAgents.ts` |
+| Plugins | `{pluginRoot}/agents/*.md`, `*.agent.md` | `agent-loader.ts` |
+| Builtin | `src/agents/definitions/*.agent.yaml` | YAML agent loader |
+
+### 4.2 Priority Rules
+
+- `*.agent.md` takes precedence over `*.md` when both exist for the same base name.
+- `.github/agents/` sources have higher priority than `.claude/agents/`.
+
+### 4.3 Frontmatter Schema
+
+```yaml
+---
+name: agent-name
+displayName: "Human-Readable Name"
+description: "What this agent does"
+tools: ["*"]                          # or ["tool1", "tool2"] — required
+model: claude-sonnet-4-20250514                  # Optional model override
+disableModelInvocation: false         # Cannot be auto-invoked as a tool
+userInvocable: true                   # User can select it
+mcp-servers:                          # Inline MCP server config (optional)
+  server-name:
+    command: "npx"
+    args: ["@some/mcp-server"]
+---
+
+Agent system prompt content here...
+Supports {{cwd}} placeholder.
+```
+
+---
+
+## 5. MCP Servers
+
+Model Context Protocol servers that expose additional tools and resources.
+
+### 5.1 Config Sources (merge order, last wins)
+
+| Priority | Source | File Pattern | Code Reference |
+|----------|--------|-------------|----------------|
+| 1 (lowest) | User | `~/.copilot/mcp-config.json` | `mcp-config.ts` |
+| 2 | Workspace | `{cwd}/.mcp.json` | `mcpConfigMerger.ts` |
+| 3 | VSCode | `{cwd}/.vscode/mcp.json` | `vsCodeWorkspaceMcpConfig.ts` |
+| 4 | Plugins | `{pluginRoot}/.mcp.json`, `{pluginRoot}/.github/mcp.json` | `mcp-loader.ts` |
+| 5 | Windows ODR | Registry `HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Mcp` | `odrMcpRegistry.ts` |
+| 6 (highest) | CLI flag | `--additional-mcp-config <json\|@filepath>` | `mcpConfigMerger.ts` |
+
+### 5.2 Config Schema
+
+```json
+{
+  "mcpServers": {
+    "server-name": {
+      "type": "local | http | sse",
+      "command": "path/to/server",

+
+## 6. Hooks
+
+Scripts that execute at specific agent lifecycle events, with the ability to approve/deny/modify behavior.
+
+### 6.1 Config Sources
+
+| Source | File Pattern | Code Reference |
+|--------|-------------|----------------|
+| Config dirs | `{configDir}/**/*.json` | `hookConfigLoader.ts` |
+| Plugins | `{pluginRoot}/hooks.json` | `hooks.ts` |
+| Plugins (alt) | `{pluginRoot}/hooks/hooks.json` | `hooks.ts` |
+| Plugin manifest | Inline in `plugin.json` → `hooks` field (object) | `hooks.ts` |
+
+### 6.2 Hook Events
+
+| Event | Trigger | Can Modify? |
+|-------|---------|-------------|
+| `sessionStart` | Session begins | No (informational) |
+| `sessionEnd` | Session ends | No (informational) |
+| `userPromptSubmitted` | User sends a message | Yes (can modify prompt) |
+| `preToolUse` | Before tool execution | Yes (allow / deny / modify args) |
+| `postToolUse` | After tool execution | Yes (can modify result) |
+| `errorOccurred` | Error happens | Yes (retry / skip / abort) |
+| `agentStop` | Main agent finishes | Yes (can force continuation) |
+| `subagentStop` | Sub-agent completes | Yes (can force continuation) |
+
+### 6.3 Config Schema
+
+```json
+{
+  "version": 1,
+  "hooks": {
+    "preToolUse": [
+      {
+        "type": "command",
+        "command": "bash",
+        "args": ["-c", "echo checking"],
+        "cwd": "/optional/cwd",
+        "env": { "KEY": "value" },
+        "timeout": 30000
+      }
+    ]
+  }
+}
+```
+
+---
+
+## 7. Plugins
+
+Bundles that install combinations of skills, agents, hooks, and MCP servers.
+
+### 7.1 Plugin Manifest Locations
+
+Within a plugin repository, the manifest is searched at:
+
+| File Pattern | Code Reference |
+|-------------|----------------|
+| `plugin.json` | `marketplace-loader.ts` PLUGIN_JSON_PATHS |
+| `.github/plugin/plugin.json` | `marketplace-loader.ts` PLUGIN_JSON_PATHS |
+| `.claude-plugin/plugin.json` | `marketplace-loader.ts` PLUGIN_JSON_PATHS |
+
+
+Each field (`skills`, `agents`, `hooks`) can be a string path, array of paths, or (for hooks) an inline object.
+
+---
+
+## Appendix A: XDG Base Directory Compliance
+
+All `~/.copilot/` paths respect XDG overrides:
+
+| Type | Default | XDG Override |
+|------|---------|-------------|
+| Config files | `~/.copilot/` | `$XDG_CONFIG_HOME/.copilot/` |
+| State/cache | `~/.copilot/` | `$XDG_STATE_HOME/.copilot/` |
+
+The base directory name is always `.copilot` (`APP_DIRECTORY` in `path-helpers.ts`).
+
+---

+
+# Commit Changes
+
+Help the user commit code changes with a well-crafted commit message derived from the diff, following the conventions already established in the repository.
+
+## Guidelines
+
+- **Never amend existing commits** without asking.
+- **Never force-push or push** without explicit user approval.
+- **Never skip pre-commit hooks** (do not use `--no-verify`).
+- **Never skip signing commits** (do not use `--no-gpg-sign`).
+- **Never revert, reset, or discard user changes** unless the user explicitly asked for that.
+- Check for obvious secrets or generated artifacts that should not be committed. If something looks risky - ask the user.
+- When in doubt about staging, convention, or message content — ask the user.
+
+## Workflow
+
+### 1. Discover the repository's commit convention
+
+Run the following to sample recent commits and the user's own commits:
+
+```
+# Recent repo commits (for overall style)
+git log --oneline -20
+
+# User's recent commits (for personal style)
+git log --oneline --author="$(git config user.name)" -10
+```
+
+Analyse the output to determine the commit message convention used in the repository (e.g. Conventional Commits, Gitmoji, ticket-prefixed, free-form). All generated messages **must** follow the detected convention.
+
+### 2. Check repository status
+
+```
+git status --short
+```
+
+- If there are **no changes** (working tree clean, nothing staged), inform the user and stop.
+- If there are **staged changes**, proceed with those and do not stage any unstaged changes.
+- If there are **only unstaged changes**, stage everything (`git add -A`), and proceed with those.
+
+### 3. Generate the commit message
+
+Obtain the full diff of what will be committed:
+
+```bash
+git diff --cached --stat
+git diff --cached
+```
+
+Using the diff and the commit convention detected in step 1, draft a commit message with:
+
+- A **subject line** (≤ 72 characters) that summarises the change, following the repository's convention.
+- An optional **body** that explains *why* the change was made, only when the diff is non-trivial.
+- Reference issue/ticket numbers when they appear in branch names or related context.
+- Focus on the intent of the change, not a file-by-file inventory.
+
+### 4. Commit
+
+Construct the `git commit` command with the generated message.
+
+Execute the commit:
+
+```
+git commit -m "<subject>" -m "<body>"
+```
+
+### 5. Confirm
+
+After the commit:
+
+- Run `git status --short` to confirm the commit completed.
+- Run `git log --oneline -1` to show the new commit.
+- If pre-commit hooks changed files or blocked the commit, summarize exactly what happened.
+- If hooks rewrote files after the commit attempt, do not amend automatically. Tell the user what changed and ask whether they want you to stage and commit those follow-up edits.

+
+# Generate Run Commands
+
+Help the user set up run commands for the current Agent Session workspace. Run commands appear in the session's Run button in the title bar.
+
+## Understanding the task schema
+
+A run command is a `tasks.json` task with:
+- `"inSessions": true` — required: makes the task appear in the Sessions run button
+- `"runOptions": { "runOn": "worktreeCreated" }` — optional: auto-runs the task whenever a new worktree is created (use for setup/install commands)
+
+```json
+{
+  "tasks": [
+    {
+      "label": "Install dependencies",
+      "type": "shell",
+      "command": "npm install",
+      "inSessions": true,
+      "runOptions": { "runOn": "worktreeCreated" }
+    },
+    {
+      "label": "Start dev server",
+      "type": "shell",
+      "command": "npm run dev",
+      "inSessions": true
+    }
+  ]
+}
+```
+
+## Decision logic
+
+**First, read the existing `.vscode/tasks.json`** to check for existing run commands (`inSessions: true` tasks).
+
+**If run commands already exist:** treat this as a modify request — ask the user what they'd like to change (add, remove, or update a command).
+
+**If no run commands exist:** try to infer the right commands from the workspace:
+- Check `package.json`, `Makefile`, `pyproject.toml`, `Cargo.toml`, `go.mod`, `.nvmrc`, or other project files to understand the stack and common commands.
+- If it's clear what the setup command is (e.g., `npm install`, `pip install -r requirements.txt`), add it with `"runOptions": { "runOn": "worktreeCreated" }` — no need to ask.
+- If it's clear what the primary run/dev command is (e.g., `npm run dev`, `cargo run`), add it with just `"inSessions": true`.
+- **Only ask the user** if the commands are ambiguous (e.g., multiple equally valid options, no recognizable project structure, or the project uses a non-standard setup).
+
+## Writing the file
+
+Always write to `.vscode/tasks.json` in the workspace root. If the file already exists, merge — do not overwrite unrelated tasks.
+
+After writing, briefly confirm what was added and how to trigger it from the Run button.

+# Merge Changes

+Merge the topic branch (checked out in the current worktree) into the merge base branch (checked out in the main worktree). The context block appended to the prompt contains the source branch, target branch, and main worktree path.
+
+## Guidelines
+
+- **Never force-push** (`--force`, `--force-with-lease`) without explicit user approval.
+- **Never skip pre-push hooks** (do not use `--no-verify`).
+- **Never rewrite or drop commits** without asking the user.
+- When in doubt about conflict resolution — ask the user.
+
+## Workflow
+
+### 1. Commit uncommitted changes in the current worktree
+
+Check for uncommitted changes in the current worktree:
+```
+git status --porcelain
+```
+If there are uncommitted changes, use the `/commit` skill to commit them before continuing.
+
+### 2. Merge the topic branch into the base branch
+
+Use `git -C <main-worktree-path>` to run commands against the main worktree without leaving the current worktree.
+
+```
+git -C <main-worktree-path> merge <topic-branch>
+```
+
+### 3. Handle merge conflicts
+
+If the merge reports conflicts:
+
+3.1. List conflicted files:
+```
+git -C <main-worktree-path> diff --name-only --diff-filter=U
+```
+
+3.2. For each conflicted file, read the file content, resolve the conflict by preserving the intent of both sides, and stage the resolved file:
+```
+git -C <main-worktree-path> add <resolved-file>
+```
+
+3.3. When in doubt on how to resolve a merge conflict, ask the user for guidance. If the user wants to abort, run:
+```
+git -C <main-worktree-path> merge --abort
+```
+
+3.4. Once all conflicts are resolved and staged, commit the merge:
+```
+git -C <main-worktree-path> commit --no-edit
+```
+
+## Validation
+
+After the merge completes, verify the result:
+
+1. Confirm the main worktree is clean:
+```
+git -C <main-worktree-path> status --porcelain
+```
+
+2. Confirm the topic branch is an ancestor of the base branch (i.e. all commits are merged):
+```
+git -C <main-worktree-path> merge-base --is-ancestor <topic-branch> HEAD
+```

+      ```

+   3.5. If the branch has local commits (ahead > 0), push them to the remote after a successful rebase.
+      ```
+      git push
+      ```
+      If the push is rejected because the rebase rewrote history, explain the situation to the user and ask for approval before force-pushing.
+4. If the current session branch does not have an upstream branch:
+   4.1. Determine the remote to publish to.
+      - If there is only one remote, use it.
+      - If there are multiple remotes, use the #tool:vscode/askQuestions tool to ask which remote to use.
+   4.2. Publish the current branch and set upstream in one step.
+      ```
+      git push -u <remote> HEAD
+      ```
+
+## Validation
+
+After the workflow completes, validate the result with explicit checks:

+1. Verify the working tree is clean:
+   ```
+   git status --porcelain
+   ```
+2. Verify sync state (ahead/behind counts are both 0):
+   ```

+# Update Skills & Instructions
+
+When a major repository learning is discovered — a recurring pattern, a non-obvious pitfall, a crucial architectural constraint, or domain knowledge that would save future sessions significant time — capture it as a skill or instruction so it persists across sessions.
+
+## When to Use
+
+- The user explicitly says **"learn!"** or asks to capture a learning
+- You discover a significant pattern or constraint that cost meaningful debugging time
+- You identify reusable domain knowledge that isn't documented anywhere in the repo
+- A correction from the user reveals a general principle worth preserving
+
+## Decision: Skill vs Instruction vs Learning

+**Add a learning to an existing instruction** when:
+- The insight is small (1-4 sentences) and fits naturally into an existing instruction file
+- It refines or extends an existing guideline
+- Follow the pattern in `.github/instructions/learnings.instructions.md`
+
+**Create or update a skill** (`.github/skills/{name}/SKILL.md` or `.agents/skills/{name}/SKILL.md`) when:
+- The knowledge is substantial (multi-step procedure, detailed guidelines, or rich examples)
+- It covers a distinct domain area (e.g., "how to debug X", "patterns for Y")
+- Future sessions should be able to invoke it by name
+
+**Create or update an instruction** (`.github/instructions/{name}.instructions.md`) when:
+- The rule should apply automatically based on file patterns (`applyTo`) or globally
+- It's a coding convention, architectural constraint, or process rule
+- It doesn't need to be invoked on demand
+
+## Procedure
+
+### 1. Identify the Learning
+
+Reflect on what went wrong or what was discovered:
+- What was the problem or unexpected behavior?
+- Why was it a problem? (root cause, not symptoms)
+- How was it fixed or what's the correct approach?
+- Can it be generalized beyond this specific instance?
+
+### 2. Check for Existing Files
+
+Before creating new files, search for existing skills and instructions that might be the right home:
+
+```
+# Check existing skills
+ls .github/skills/ .agents/skills/ 2>/dev/null
+
+# Check existing instructions
+ls .github/instructions/ 2>/dev/null
+
+# Search for related content
+grep -r "related-keyword" .github/skills/ .github/instructions/ .agents/skills/
+```
+
+### 3a. Add to Existing File
+
+If an appropriate file exists, add the learning to its `## Learnings` section (create the section if it doesn't exist). Each learning should be 1-4 sentences.
+
+### 3b. Create a New Skill
+
+If the knowledge warrants a standalone skill:
+
+1. Choose the location:
+   - `.github/skills/{name}/SKILL.md` for project-level skills (committed to repo)
+   - `.agents/skills/{name}/SKILL.md` for agent-specific skills
+2. Create the directory and SKILL.md with frontmatter:
+
+```markdown
+---
+name: {skill-name}
+description: {One-line description of when and why to use this skill.}
+---
+
+# {Skill Title}
+
+{Body with guidelines, procedures, examples, and learnings.}
+```
+
+3. The `name` field **must match** the parent folder name exactly.
+4. Include concrete examples — skills with examples are far more useful than abstract rules.
+
+### 3c. Create a New Instruction
+
+If the knowledge should apply automatically:
+
+```markdown
+---
+description: {When these instructions should be loaded}
+applyTo: '{glob pattern}' # optional — auto-load when matching files are attached
+---
+
+{Content of the instruction.}
+```
+
+### 4. Quality Checks
+
+Before saving:
+- Is the learning **general enough** to help future sessions, not just this one?
+- Is it **specific enough** to be actionable, not just a vague principle?
+- Does it include a **concrete example** of right vs wrong?
+- Does it avoid duplicating knowledge already captured elsewhere?
+- Is the description clear enough that the agent will know **when** to invoke/apply it?
+
+### 5. Inform the User
+
+After creating or updating the file:
+- Summarize what was captured and where
+- Explain why this location was chosen
+- Note if any existing content was updated vs new content created

+# AI Customizations Test Plan
+
+The following test plan outlines the scenarios and specifications for the AI Customizations feature, which includes a management editor and tree view for managing customization items.
+
+## SPECS
+
+- [`../AI_CUSTOMIZATIONS.md`](../AI_CUSTOMIZATIONS.md)
+
+## SCENARIOS
+
+### Scenario 1: Empty state — no session, no customizations
+
+#### Description
+
+This tests the baseline empty state before any session or workspace is active. The 'new AI developer' state - who doesn't have any customizations on their machine yet.
+
+#### Preconditions
+
+- On 'New Session' screen
+- No folder selected
+- No user customizations created (from this tool or others i.e. Copilot CLI)
+
+#### Actions
+
+1. Open the sidebar customizations section
+2. Observe no sidebar counts are shown for any section (Agents, Skills, Instructions, Prompts, Hooks)
+3. Open the management editor by clicking on one of the sections (e.g., "Instructions")
+4. Observe the empty state messages
+5. Click through each section in the sidebar
+6. Run Developer: Customizations Debug and read the report
+
+#### Expected Results
+
+- All sidebar counts are hidden (no badges visible)
+- Management editor shows empty state for each section with "No X yet" message
+- Create button for **user** customizations is visible but disabled until a workspace folder or repository is selected (Hooks should also show a disabled button, since there is no 'user' scoped hooks)
+
+#### Notes
+
+- The `Window: Sessions` should be verified by running `Developer: Customizations Debug`
+- No workspace root should be active, verified via `Developer: Customizations Debug` (active root = none)
+
+---
+
+### Scenario 2: Active workspace selected from new session state
+
+#### Description
+
+This tests the transition from the empty state to having an active workspace selected, but before a worktree is checked out (i.e., before starting a task). This is the 'new session' state where the user has selected a repository but hasn't started working in a specific branch or worktree yet. Customizations should be loaded from the repository root, not a worktree, and counts should reflect that.
+
+#### Preconditions
+
+- On 'New Session' screen (Scenario 1 completed)
+- A git repository, cloned on the machine, is available to select
+  - For this test use `microsoft/vscode` cloned to a test folder
+
+#### Actions
+
+1. From the new session screen, select a workspace folder
+2. Observe the sidebar customization counts update
+3. Open the management editor by clicking on "Instructions"
+4. Observe items appear in the "Workspace" group
+5. Note the workspace item count in the group header
+6. Compare the sidebar badge count with the editor's workspace item count — they should match
+7. Click "Agents" in the sidebar
+8. Observe agent items listed with parsed friendly names (not raw filenames) and a description
+9. Click "Skills" in the sidebar
+10. Observe skills listed with names derived from folder names
+11. Click "Prompts" in the sidebar
+12. Observe only prompt-type items (no skills mixed in, although note there may be similarly named items)
+13. Click "Hooks" in the sidebar
+14. Observe only workspace-scoped hook files (no user-level `~/.claude/settings.json`)
+15. Run Developer: Customizations Debug and read the report
+
+#### Expected Results
+
+- Sidebar counts update from 0 to reflect the selected workspace's customizations
+- Sidebar badge count matches editor list count for every section
+- Instructions includes root-level files (AGENTS.md, CLAUDE.md, copilot-instructions.md) under "Workspace"
+- Instructions includes `.instructions.md` files from `.github/instructions/`
+- Agents shows friendly names (e.g., "Optimize" not "optimize.agent.md")
+- Prompts excludes skill-type slash commands
+- Hooks shows only workspace-local files (filter: `sources: [local]`)
+- No "Extensions" or "Plugins" groups visible
+- If user-level files exist in `~/.copilot/` or `~/.claude/`, a "User" group appears for applicable sections
+- Debug report shows `Window: Sessions`, `Active root: /path/to/repository`
+- Create button shows both "Workspace" and "User" options in dropdown
+
+#### Notes
+
+- The active root comes from the repository, not a worktree
+
+---
+
+### Scenario 3: Create new workspace instruction in an active worktree session
+
+#### Preconditions
+
+- Active session with a worktree checked out (task started and running)
+- Use the same repository as Scenario 2 (`microsoft/vscode`)
+
+#### Actions
+
+1. Observe sidebar customization counts reflect the worktree's customizations and are the same as Scenario 2 (since new worktree inherits from repo root, counts should be the same)
+2. Open the management editor by clicking on "Instructions"
+3. Observe items listed — should match files in the worktree (not the bare repo)
+4. Verify there is a primary button "New Instructions (Workspace)" and another option in the dropdown for "New Instructions (User)"
+5. Click the "+ New Instructions (Workspace)" button (primary action)
+6. Select a name `<name>` when the quickpick appears and confirm
+7. Verify the file opens in the embedded editor
+8. Verify the file path shown in the editor header is `<WORKTREE_PATH>/.github/instructions/<name>.instructions.md`
+9. Update the instruction file with some content, then press the back button
+10. Confirm the instruction file was auto-committed and shows up in the worktree changes list
+11. Reopen the customization management editor and click on "Instructions" again
+12. Observe the new instruction appears in the "Workspace" group
+13. Observe the sidebar badge count has incremented by 1
+
+#### Expected Results
+
+- Active root is the worktree path, not the repository path
+- File is created under the worktree's `.github/instructions/` folder (not the bare repo)
+- File auto-saves and auto-commits to the worktree
+- Item count updates in both the sidebar badge and editor list after creation
+- The new file appears in the list with a friendly name derived from the filename
+
+#### Notes
+
+- This is the primary creation flow — workspace instructions are the most common customization type
+- Key difference from Scenario 2: active root is the worktree, creation targets the worktree
+
+---
+
+### Scenario 4: Create new user instruction in an active worktree session
+
+#### Preconditions
+
+- Active session with a worktree checked out (continuing from Scenario 3)
+
+#### Actions
+
+1. Open the management editor by clicking on "Instructions"
+2. Click the "Add" dropdown arrow → click "New Instruction (User)"
+3. Select a name `<name>` when the quickpick appears and confirm
+4. Verify the file opens in the embedded editor
+5. Verify the file path shown in the editor header is `~/.copilot/instructions/<name>.instructions.md`
+6. Confirm the path is NOT the VS Code profile folder (e.g., NOT `~/.vscode-oss-sessions-dev/User/...`)
+7. Press the back button to return to the list
+8. Observe the new instruction appears in the "User" group
+9. Observe the sidebar badge count reflects the new user instruction
+10. Run Developer: Customizations Debug
+11. Check the "Source Folders (creation targets)" section — verify `[user]` points to `~/.copilot/instructions`
+
+#### Expected Results
+
+- User file is created under `~/.copilot/instructions/` (not the VS Code profile folder)
+- The file appears in the "User" group in the list
+- Sidebar badge count includes the new user file
+- Debug report confirms the user creation target is `~/.copilot/instructions`
+
+#### Notes
+
+- This validates that `AgenticPromptsService.getSourceFolders()` correctly redirects user creation to `~/.copilot/`
+- The VS Code profile folder should never be used for user creation in sessions
+
+---
+
+### Scenario 5: Create a new hook in an active worktree session
+
+#### Preconditions
+
+- Active session with a worktree checked out (continuing from Scenario 3)
+- No existing `hooks.json` in the worktree's `.github/hooks/` folder
+
+#### Actions
+
+1. Open the management editor by clicking on "Hooks"
+2. Observe the current hook items (if any)
+3. Click the "Add" button → observe a `hooks.json` is created
+4. Verify the hooks.json opens in the embedded editor
+5. Verify the file path is `<WORKTREE_PATH>/.github/hooks/hooks.json`
+6. Read the generated JSON and check:
+   - `"version": 1` is present at the top level
+   - Hook entries use `"bash"` as the shell field (not `"command"`)
+   - All hook event types are present: `sessionStart`, `userPromptSubmitted`, `preToolUse`, `postToolUse`
+   - Each event has a `[{ "type": "command", "bash": "" }]` skeleton
+7. Edit one of the hook entries (e.g., add a bash command to `sessionStart`)
+8. Press the back button to return to the list
+9. Observe the hooks.json appears in the "Workspace" group
+10. Observe the sidebar badge count for Hooks has updated
+11. Run Developer: Customizations Debug on the Hooks section
+12. Verify `Active root` points to the worktree path
+13. Compare Stage 1 counts with Stage 3 counts — they should be consistent
+
+#### Expected Results
+
+- Hooks.json is created in the worktree's `.github/hooks/` folder
+- JSON skeleton has correct Copilot CLI format: `"version": 1`, `"bash"` field
+- All hook events from `COPILOT_CLI_HOOK_TYPE_MAP` are present in the skeleton
+- Hooks section shows only workspace-local hook files (no user-level hooks visible)
+- Item count updates after creation
+- Debug report Stage 1 → Stage 3 pipeline shows no unexpected filtering
+
+#### Notes
+
+- Hook events are derived from `COPILOT_CLI_HOOK_TYPE_MAP` — adding new events to the schema auto-includes them in the skeleton
+- Only `"bash"` is used (not `"command"`) to match the Copilot CLI schema
+- The `"version": 1` field is required by the CLI for format detection

+# Agent Sessions — E2E Tests
+
+Automated dogfooding tests for the Agent Sessions window using a
+**compile-and-replay** architecture powered by
+[`playwright-cli`](https://github.com/microsoft/playwright-cli) and Copilot CLI.
+
+## Mocking Architecture
+
+These tests run the **real** Sessions workbench with only the minimal set of
+services mocked — specifically the services that require external backends
+(auth, LLM, git). Everything downstream from the mock agent's canned response
+runs through the real code paths.
+
+### What's Mocked (Minimal)
+
+| Service | Mock | Why |
+|---------|------|-----|
+| `IChatEntitlementService` | Returns `ChatEntitlement.Free` | No real Copilot account in CI |
+| `IDefaultAccountService` | Returns a fake signed-in account | Hides the "Sign In" button |
+| `IGitService` | Resolves immediately (no 10s barrier) | No real git extension in web tests |
+| Chat agents (`copilotcli`, etc.) | Canned keyword-matched responses with `textEdit` progress items | No real LLM backend |
+| `mock-fs://` FileSystemProvider | `InMemoryFileSystemProvider` registered directly in the workbench (not extension host) | Must be available before any service tries to resolve workspace files |
+| GitHub authentication | Always-signed-in mock provider (extension) | No real OAuth flow |
+| Code Review command | Returns canned review comments per file (extension) | No real Copilot AI review |
+| PR commands (Create/Open/Merge) | No-op handlers that log and show info messages (extension) | No real GitHub API |
+
+### What's Real (Everything Else)
+
+The following services run with their **real** implementations, ensuring tests
+exercise the actual code paths:
+
+- **`ChatEditingService`** — Processes `textEdit` progress items from the mock
+  agent, creates `IModifiedFileEntry` objects with real before/after diffs, and
+  computes actual `linesAdded`/`linesRemoved` from content changes
+- **`ChatModel`** — Routes agent progress through `acceptResponseProgress()`
+- **`ChangesViewPane`** — Reads file modification state from `IChatEditingService`
+  observables and renders the tree with real diff stats
+- **Diff editor** — Opens a real diff view when clicking files in the changes list
+- **Context keys** — `hasUndecidedChatEditingResourceContextKey`,
+  `hasAppliedChatEditsContextKey` are set by real `ModifiedFileEntryState`
+  observations
+- **Menu actions** — "Create PR", "Accept", "Reject" buttons appear based on
+  real context key state
+- **`CodeReviewService`** — Orchestrates review requests, processes results from
+  the mock `github.copilot.chat.codeReview.run` command, and stores comments
+- **`CodeReviewToolbarContribution`** — Shows the Code Review button in the
+  Changes view toolbar based on real context key state
+
+### Data Flow
+
+```
+User types message → Chat Widget → ChatService
+  → Mock Agent invoke() → progress([{ kind: 'textEdit', uri, edits }])
+    → ChatModel.acceptResponseProgress()
+      → ChatEditingService observes textEditGroup parts
+        → Creates IModifiedFileEntry per file
+        → Reads original content from mock-fs:// FileSystemProvider
+        → Computes real diff (linesAdded, linesRemoved)
+          → ChangesViewPane renders via observable chain
+            → Click file → Opens real diff editor
+```
+
+The mock agent is the **only** point where canned data enters the system.
+Everything downstream uses real service implementations.
+
+### Code Review & PR Button Flow
+
+```
+Code Review button clicked → sessions.codeReview.run (core action)
+  → CodeReviewService.requestReview()
+    → commandService.executeCommand('chat.internal.codeReview.run')
+      → Bridge forwards to 'github.copilot.chat.codeReview.run'
+        → Mock extension returns canned comments
+          → CodeReviewService stores results, updates observable state
+            → CodeReviewToolbarContribution updates button icon/badge
+
+Create PR button clicked → github.copilot.chat.createPullRequestCopilotCLIAgentSession.createPR
+  → Mock extension logs and shows info message
+```
+
+The PR buttons (Create PR, Open PR, Merge) are contributed via the mock
+extension's `package.json` menus, gated by `chatSessionType == copilotcli`.
+The `chatSessionType` context key is derived from the session URI scheme
+(`getChatSessionType()`), which returns `copilotcli` for mock sessions.
+
+### Why the FileSystem Provider Is Registered in the Workbench
+
+The `mock-fs://` `InMemoryFileSystemProvider` is registered directly on
+`IFileService` inside `TestSessionsBrowserMain.createWorkbench()` — **not** in
+the mock extension. This is critical because several workbench services
+(SnippetsService, AgenticPromptFilesLocator, MCP, etc.) try to resolve files
+in the workspace folder **before** the extension host activates. If the
+provider were only registered via `vscode.workspace.registerFileSystemProvider()`
+in the extension, these services would see `ENOPRO: No file system provider`
+errors and fail silently.
+
+The mock extension still registers a `mock-fs` provider via the extension API
+(needed for extension host operations), but the workbench-level registration
+is the source of truth.
+
+### File Edit Strategy
+
+Mock edits target files that exist in the `mock-fs://` file store so the
+`ChatEditingService` can compute real before/after diffs:
+
+- **Existing files** (e.g. `/mock-repo/src/index.ts`, `/mock-repo/package.json`) — edits use a
+  full-file replacement range (`line 1 → line 99999`) so the editing service
+  diffs the old content against the new content
+- **New files** (e.g. `/mock-repo/src/build.ts`) — edits use an insert-at-beginning
+  range, producing a "file created" entry in the changes view
+
+### Mock Workspace Folder
+
+The workspace folder URI is `mock-fs://mock-repo/mock-repo`. The path
+`/mock-repo` (not root `/`) is used so that `basename(folderUri)` returns
+`"mock-repo"` — this is what the folder picker displays. All mock files are
+stored under this path in the in-memory file store.
+
+## How It Works
+
+There are two phases:
+
+### Phase 1: Generate (uses LLM — slow, run once)
+
+```bash
+npm run generate
+```
+
+For each `.scenario.md` file, the generate script:
+1. Starts the Sessions web server and opens the page in `playwright-cli`
+2. Takes an accessibility tree snapshot of the current page
+3. Sends each natural-language step + snapshot to **Copilot CLI**, which returns
+   the exact `playwright-cli` commands (e.g. `click e43`, `type "hello"`)
+4. Executes the commands to advance the UI state for the next step
+5. Writes the compiled commands to a `.commands.json` file in the `scenarios/generated/` folder
+
+```
+scenarios/
+├── 01-repo-picker-on-submit.scenario.md       ← human-written
+├── 02-cloud-disables-add-run-action.scenario.md
+└── generated/
+    ├── 01-repo-picker-on-submit.commands.json  ← agent-generated
+    └── 02-cloud-disables-add-run-action.commands.json
+```
+
+The `.commands.json` files are **committed to git** — they're the deterministic
+test plan that everyone runs.
+
+### Phase 2: Test (no LLM — fast, deterministic)
+
+```bash
+npm test
+```
+
+The test runner reads each `.commands.json` and replays the `playwright-cli`
+commands mechanically. No LLM calls, no regex matching, no icon stripping.
+Just sequential commands and assertions.
+
+### When to Re-generate
+
+Run `npm run generate` when:
+- You add a new `.scenario.md` file
+- The UI changes and refs are stale (tests start failing)
+- You modify an existing scenario's steps
+

+
+## Prerequisites
+
+- VS Code compiled (`out/` at the repo root):
+  ```bash
+  npm install && npm run compile
+  ```
+- Dependencies installed:
+  ```bash
+  cd src/vs/sessions/test/e2e && npm install
+  ```
+- Copilot CLI available (for `npm run generate` only):
+  ```bash
+  copilot --version
+  ```
+
+## Running
+
+```bash
+cd src/vs/sessions/test/e2e
+
+# First time or after UI changes:
+npm run generate
+
+# Run tests (fast, deterministic):
+npm test
+```
+
+Example test output:
+
+```
+Found 2 compiled scenario(s)
+
+Starting sessions web server on port 9542…
+Server ready.
+
+▶ Scenario: Repository picker opens when submitting without a repo
+  ✅   step 1: Click button "Cloud"
+  ✅   step 2: Type "build the project" in the chat input
+  ✅   step 3: Press Enter to submit
+  ✅   step 4: Verify the repository picker dropdown is visible
+
+▶ Scenario: Switching to Cloud target disables the Add Run Action button
+  ✅   step 1: Click button "Cloud"
+  ✅   step 2: Click button "Local"
+
+Results: 6 passed, 0 failed
+```
+
+## Writing a New Scenario
+
+1. Create a new `NN-description.scenario.md` file in `scenarios/`.
+   Files are sorted by name and run in order.
+
+2. Use this format:
+
+```markdown
+# Scenario: Short description of what this tests
+
+## Steps
+1. Click button "Cloud"
+2. Type "build the project" in the chat input
+3. Press Enter to submit
+4. Verify the repository picker dropdown is visible
+```
+
+3. Run `npm run generate` to compile it into a `.commands.json` file.
+
+4. Run `npm test` to verify it works.
+
+5. Commit both the `.scenario.md` and `.commands.json` files.
+
+### Step Language
+
+Write steps in plain English. The Copilot agent interprets them against the
+page's accessibility tree. Common patterns:
+
+| Pattern | Example |
+|---------|---------|
+| Click a button | `Click button "Cloud"` |
+| Type in an input | `Type "hello" in the chat input` |
+| Press a key | `Press Enter` |
+| Verify visibility | `Verify the repository picker dropdown is visible` |
+| Verify button state | `Verify the "Send" button is disabled` |
+
+You're not limited to these patterns — the agent understands natural language.
+
+### The .commands.json Format
+
+Each compiled step looks like:
+
+```json
+{
+  "description": "Click button \"Cloud\"",
+  "commands": [
+    "click e143"
+  ]
+}
+```
+
+For assertions, the agent outputs a `snapshot` command followed by an assertion comment:
+
+```json
+{
+  "description": "Verify the repository picker dropdown is visible",
+  "commands": [
+    "snapshot",
+    "# ASSERT_VISIBLE: Repository Picker"
+  ]
+}
+```
+
+The test runner understands these comment-based assertions:
+- `# ASSERT_VISIBLE: <text>` — checks snapshot contains the text
+- `# ASSERT_DISABLED: <label>` — checks button has `[disabled]`
+- `# ASSERT_ENABLED: <label>` — checks button doesn't have `[disabled]`
+
+### How a Step Executes (Worked Example)
+
+Let's trace `Click button "Cloud"` through both phases.
+
+**Generate phase** — the agent sees the accessibility tree snapshot:
+
+```yaml
+- group "Session target"
+  - button "Local" [ref=e141]
+  - button "Cloud" [ref=e143]
+```
+
+Copilot CLI returns: `click e143`
+
+This is saved to `.commands.json` and the click is executed to advance state.
+
+**Test phase** — the runner reads:
+
+```json
+{ "commands": ["click e143"] }
+```
+
+It shells out to `playwright-cli click e143`. Done. No parsing, no matching.
+
+### Tips
+
+- **Use exact button labels** as they appear in the UI.
+- **One action per step** — keep steps atomic for clear failure messages.
+- **Order matters** — scenarios run sequentially; an Escape is pressed between them.
+- **Prefix filenames** with numbers (`01-`, `02-`, …) to control execution order.
+- **Re-generate selectively**: `npm run generate -- 01-repo` to recompile one scenario.
+
+### Testing File Diffs
+
+To test that chat responses produce real file diffs:
+
+1. Use a message keyword that triggers file edits in the mock agent
+   (e.g. "build", "fix" — see `getMockResponseWithEdits()` in `web.test.ts`)
+2. The mock agent emits `textEdit` progress items that flow through the
+   **real** `ChatEditingService`
+3. Open the secondary side bar to see the Changes view
+4. Assert file names are visible in the changes tree
+5. Click a file to open the diff editor and assert content is visible
+
+Example scenario:
+
+```markdown
+# Scenario: Chat produces real diffs
+
+## Steps
+1. Type "build the project" in the chat input
+2. Press Enter to submit
+3. Verify there is a response in the chat
+4. Toggle the secondary side bar
+5. Verify the changes view shows modified files
+6. Click on "index.ts" in the changes list
+7. Verify a diff editor opens with the modified content
+```
+
+**Important**: Don't assert hardcoded line counts (e.g. `+23`). Instead assert
+on file names and content snippets — the real diff engine computes the actual
+counts, which may change as mock file content evolves.
+
+### Adding Mock File Edits
+
+To add new keyword-matched responses with file edits, update
+`getMockResponseWithEdits()` in `src/vs/sessions/test/web.test.ts`:
+
+1. **For existing files** — target URIs whose paths match `EXISTING_MOCK_FILES`
+   (files pre-seeded in the mock extension's file store). The `emitFileEdits()`
+   helper uses a full-file replacement range so the `ChatEditingService`
+   computes a real diff.
+2. **For new files** — target any other path. The helper uses an insert range
+   for these, producing a "file created" entry.
+3. **Mock file store** — to add or change pre-seeded files, update `MOCK_FILES`
+   in `extensions/sessions-e2e-mock/extension.js` AND update
+   `EXISTING_MOCK_FILES` in `web.test.ts` to match. All paths must be under
+   `/mock-repo/` (e.g. `/mock-repo/src/newfile.ts`).

+# Agent Plugins Architecture
+
+Agent plugins are a modular extension system that allows external packages of prompts, hooks, skills, agents, and MCP server definitions to be discovered, installed, and contributed into the chat experience. This document describes the architecture of the `src/vs/workbench/contrib/chat/common/plugins/` layer and its browser-side implementations.
+
+## Directory Structure
+
+### Common layer (`common/plugins/`)
+| File | Role |
+|------|------|
+| `agentPluginService.ts` | Core interfaces (`IAgentPlugin`, `IAgentPluginService`, `IAgentPluginDiscovery`) and the discovery registry singleton |
+| `agentPluginServiceImpl.ts` | `AgentPluginService` implementation, `AbstractAgentPluginDiscovery` base class, format adapters (Copilot / Claude / Open Plugin) |
+| `agentPluginRepositoryService.ts` | `IAgentPluginRepositoryService` — abstract repository clone/pull/cache operations |
+| `pluginMarketplaceService.ts` | `IPluginMarketplaceService` — marketplace metadata, installed-plugin storage, trusted-marketplace tracking, periodic update checks |
+| `pluginInstallService.ts` | `IPluginInstallService` — install/update orchestration interface |
+| `pluginSource.ts` | `IPluginSource` — per-source-kind strategy interface (install path, ensure, update, cleanup) |
+
+### Browser layer (`browser/`)
+| File | Role |
+|------|------|
+| `agentPluginRepositoryService.ts` | Browser implementation of `IAgentPluginRepositoryService` (git clone/pull via Git service) |
+| `pluginSources.ts` | Concrete `IPluginSource` implementations: `GitHubPluginSource`, `GitUrlPluginSource`, `NpmPluginSource`, `PipPluginSource`, `RelativePathPluginSource` |
+| `pluginInstallService.ts` | Browser implementation of `IPluginInstallService` |
+| `agentPluginsView.ts` | Installed-plugins tree view UI |
+| `agentPluginActions.ts` | Context-menu actions for plugins |
+| `agentPluginEditor/` | Rich editor for browsing a single plugin's contents |
+
+## Core Interfaces
+
+### IAgentPlugin
+
+Represents a single discovered plugin:
+
+```
+uri              – Unique filesystem URI for the plugin root
+label            – Human-readable display name
+enablement       – Observable enable/disable state (ContributionEnablementState)
+hooks            – Observable list of IAgentPluginHook
+commands         – Observable list of IAgentPluginCommand  (*.md files in commands/)
+skills           – Observable list of IAgentPluginSkill    (dirs with SKILL.md in skills/)
+agents           – Observable list of IAgentPluginAgent    (*.md files in agents/)
+mcpServerDefinitions – Observable list of IAgentPluginMcpServerDefinition
+fromMarketplace  – Set when the plugin was installed from a marketplace
+remove()         – Removes this plugin from its discovery source
+```
+
+### IAgentPluginService
+
+Main entry point consumed by the rest of the workbench:
+
+```
+plugins          – IObservable<readonly IAgentPlugin[]>  (aggregate of all discoveries, deduped by URI)
+enablementModel  – Shared IEnablementModel for plugin enable/disable state
+```
+
+Registered as `InstantiationType.Delayed` — only instantiated when first injected.
+
+### IAgentPluginDiscovery
+
+Strategy for finding plugins from a particular source:
+
+```
+plugins  – IObservable<readonly IAgentPlugin[]>
+start(enablementModel) – Begin watching the source
+```
+
+Discoveries are registered into the global `agentPluginDiscoveryRegistry` singleton and instantiated by `AgentPluginService` on startup.
+
+## Discovery & Plugin Reading
+
+### AbstractAgentPluginDiscovery
+
+Shared base class that handles:
+
+1. **Format detection** — auto-detects whether a plugin uses the Copilot, Claude, or Open Plugin format based on path conventions and manifest existence.
+2. **Content reading** — reads commands, skills, agents, hooks, and MCP server definitions from the filesystem.
+3. **File watching** — watches plugin directories for changes and re-reads contents on a 200 ms debounced scheduler.
+4. **Observable propagation** — sets the `plugins` observable on each refresh cycle.
+
+Subclasses implement `_discoverPluginSources()` to determine *which* plugin URIs exist.
+
+### Discovery Implementations
+
+**ConfiguredAgentPluginDiscovery** — resolves `chat.pluginLocations` configuration entries (absolute, tilde-expanded, or workspace-relative paths) and watches for config changes.
+
+**MarketplaceAgentPluginDiscovery** — discovers plugins from `IPluginMarketplaceService.installedPlugins` and delegates to the install/repository services for on-disk availability.
+
+### Plugin Formats
+
+Three format adapters implement `IAgentPluginFormatAdapter`:
+
+| | Copilot | Claude | Open Plugin |
+|-|---------|--------|-------------|
+| Manifest | `plugin.json` | `.claude-plugin/plugin.json` | `.plugin/plugin.json` |
+| Hooks config | `hooks.json` | `hooks/hooks.json` | `hooks/hooks.json` |
+| Hook parser | `parseCopilotHooks()` | `parseClaudeHooks()` | `parseClaudeHooks()` |
+| Special handling | — | `${CLAUDE_PLUGIN_ROOT}` token replacement, `CLAUDE_PLUGIN_ROOT` env var injection | `${PLUGIN_ROOT}` token replacement, `PLUGIN_ROOT` env var injection |
+
+Auto-detection logic: if a `.plugin/plugin.json` manifest exists, the Open Plugin adapter is used; if the plugin URI path contains `.claude` or a `.claude-plugin/plugin.json` manifest exists, the Claude adapter is used; otherwise, the Copilot adapter is used.
+
+### Plugin Contents (Filesystem Layout)
+
+```
+<plugin-root>/
+├── plugin.json                                    # Copilot manifest
+├── .claude-plugin/plugin.json                     # Claude manifest
+├── .plugin/plugin.json                            # Open Plugin manifest
+├── hooks.json   OR  hooks/hooks.json              # hook definitions
+├── .mcp.json                                      # MCP server definitions (optional)
+├── commands/
+│   ├── do-thing.md                                # → IAgentPluginCommand
+│   └── other.md
+├── skills/
+│   └── my-skill/
+│       └── SKILL.md                               # → IAgentPluginSkill
+└── agents/
+    └── helper.md                                  # → IAgentPluginAgent
+```
+
+## Marketplace & Installation
+
+### IPluginMarketplaceService
+
+Manages the catalog of available and installed plugins:
+
+- **Fetch** — reads `chat.pluginMarketplaces` config (GitHub shorthand, Git URLs, or file URIs), fetches `marketplace.json` from each, and returns parsed `IMarketplacePlugin` entries.
+- **Installed storage** — persists installed plugins in application-scoped storage (`chat.plugins.installed.v1`). Each entry tracks `{ pluginUri, plugin, enabled }`.
+- **Trust** — marketplace canonical IDs must be explicitly trusted before install proceeds (`chat.plugins.trustedMarketplaces.v1`).
+- **Auto-update** — checks for upstream changes approximately every 24 hours when `extensions.autoUpdate` is enabled; sets `hasUpdatesAvailable` observable.
+- **GitHub caching** — caches raw GitHub API responses with an 8-hour TTL to avoid repeated fetches.
+
+### Marketplace Definition Files
+
+Checked in order per repository:
+1. `marketplace.json` → `MarketplaceType.OpenPlugin`
+2. `.plugin/marketplace.json` → `MarketplaceType.OpenPlugin`
+3. `.github/plugin/marketplace.json` → `MarketplaceType.Copilot`
+4. `.claude-plugin/marketplace.json` → `MarketplaceType.Claude`
+
+### IPluginInstallService
+
+Orchestrates install and update workflows:
+
+- `installPlugin()` — checks marketplace trust, delegates to the appropriate source strategy to ensure files are locally available, and registers the plugin in installed storage.
+- `updatePlugin()` / `updateAllPlugins()` — pulls latest changes for cloned repositories and re-runs package-manager installs where applicable.
+
+### Plugin Source Strategies (IPluginSource)
+
+Each `PluginSourceKind` has a strategy that knows how to compute cache paths, provision files, update, and clean up:
+
+| Kind | Provisioning | Cache path |
+|------|-------------|------------|
+| `RelativePath` | No-op (lives inside marketplace repo) | `<cacheRoot>/github.com/<owner>/<repo>/<path>` |
+| `GitHub` | `git clone` / `git pull` | `<cacheRoot>/github.com/<owner>/<repo>[/ref_<ref>]` |
+| `GitUrl` | `git clone` / `git pull` | `<cacheRoot>/<host>/<path>[/ref_<ref>]` |
+| `Npm` | `npm install` in terminal | `<cacheRoot>/npm/<sanitized-package>/` |
+| `Pip` | `pip install` in terminal | `<cacheRoot>/pip/<package>/` |
+
+## Configuration & Storage Keys
+
+### Configuration
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| `chat.pluginsEnabled` | boolean | `true` | Master switch for the plugin system |
+| `chat.pluginLocations` | `Record<string, boolean>` | `{}` | Local plugin directories to discover |
+| `chat.pluginMarketplaces` | `string[]` | `[]` | Marketplace references to fetch from |
+
+### Storage (ApplicationScope, MachineTarget)
+| Key | Description |
+|-----|-------------|
+| `chat.plugins.installed.v1` | Installed marketplace plugins |
+| `chat.plugins.trustedMarketplaces.v1` | User-trusted marketplace canonical IDs |
+| `chat.plugins.lastFetchedPlugins.v2` | Last marketplace fetch results (persisted until next fetch) |
+| `chat.plugins.marketplaces.githubCache.v1` | GitHub API response cache (8 hour TTL) |
+| `chat.plugins.lastUpdateCheck.v1` | Timestamp of last periodic update check |
+
+### Enablement Storage
+| Key | Description |
+|-----|-------------|
+| `agentPlugins.enablement` | Per-plugin enable/disable state (shared `EnablementModel`) |
+
+## Reactivity Model
+
+The entire system is built on `IObservable`:
+
+1. **Configuration observables** (`observableConfigValue`) — push changes when settings are modified.
+2. **Discovery observables** — each `IAgentPluginDiscovery` exposes an `IObservable<readonly IAgentPlugin[]>` updated on filesystem changes.
+3. **Service-level derived** — `AgentPluginService.plugins` is a `derived()` that aggregates all discovery observables, dedupes by URI, and sorts.
+4. **Per-plugin observables** — each `IAgentPlugin` has observable properties for hooks, commands, skills, agents, and MCP definitions that update independently on file changes.
+5. **UI bindings** — views and editors use `autorun()` / `derived()` to reactively render plugin state.
+
+## Integration Points
+
+- **Chat prompts** — plugin hooks are contributed to the prompt system via the hook infrastructure.
+- **MCP servers** — plugins can define MCP server configurations (stdio or SSE) that are registered with the MCP platform.
+- **AI Customization UI** — the AI customization views aggregate plugin stats alongside MCP servers, prompts, and other customization surfaces.
+- **Extension API** — the plugin system is internal; there is no public `vscode` API surface for third-party access.
+
+## Key Design Patterns
+
+- **Strategy pattern** — format adapters (`IAgentPluginFormatAdapter`) and source strategies (`IPluginSource`) allow the system to support multiple plugin formats and installation mechanisms without coupling.
+- **Discovery registry** — `agentPluginDiscoveryRegistry` decouples discovery implementations from the core service via `SyncDescriptor0<IAgentPluginDiscovery>` registration.
+- **Disposable management** — plugin entries are tracked in a `Map` keyed by URI string, each with its own `DisposableStore` for file watchers. Removal or format changes dispose the store.
+- **Debounced refresh** — filesystem changes trigger a 200 ms `RunOnceScheduler` to batch rapid edits into a single re-read.
+- **Deduplication** — multiple discoveries may produce the same plugin URI; the service dedupes via `ResourceSet` and sorts by URI for stable ordering.
+- **Lazy instantiation** — the service is registered as `InstantiationType.Delayed` and only created on first injection.

Save content to a file or memory, then set an artifact pointing to it.\n- When updating plans or documents, update both the underlying file AND the artifact list.\n- Keep artifact labels concise and descriptive.',

+# Image Carousel
+
+A generic workbench editor for viewing collections of images in a carousel/slideshow UI. Opens as a modal editor pane with navigation arrows, a caption, and a thumbnail strip.
+
+## Architecture
+
+The image carousel is a self-contained workbench contribution that follows the **custom editor** pattern:
+
+- **URI scheme**: `vscode-image-carousel` (registered in `Schemas` in `src/vs/base/common/network.ts`) — used for `EditorInput.resource` identity.
+- **Direct editor input**: Callers create `ImageCarouselEditorInput` with a collection and open it directly via `IEditorService.openEditor()`.
+- **Image extraction**: Chat integration builds a **sections-based** collection from chat request/response items. A section can include user-attached request images alongside response-derived images (tool invocations and inline references). For paired request/response items, the section title prefers the user's chat request message; pending requests with image attachments form their own section.
+
+## How to open the carousel
+
+### From code (generic)
+
+```ts
+const collection: IImageCarouselCollection = { id, title, sections: [{ title: '', images: [...] }] };
+const input = new ImageCarouselEditorInput(collection, startIndex);
+await editorService.openEditor(input, { pinned: true }, MODAL_GROUP);
+```
+
+### From chat (via click handler)
+
+Clicking an image attachment pill in chat (when `chat.imageCarousel.enabled` is true) executes the `workbench.action.chat.openImageInCarousel` command, which collects request attachment images together with response-derived images for the current chat session and opens them in the carousel. MIME types are resolved via `getMediaMime()` from `src/vs/base/common/mime.ts`.
+
+## Key design decisions
+
+### Editor & lifecycle
+
+- **Modal editor**: Opens in `MODAL_GROUP` (-4) as an overlay.
+- **Not restorable**: `canSerialize()` returns `false` — image data is in-memory only.
+- **Collection ID = chat session identity**: `sessionResource + '_carousel'` for stable dedup via `EditorInput.matches()`.
+- **Preview-gated**: `chat.imageCarousel.enabled` (default `false`, tagged `preview`). When off, clicks fall through to `openResource()`.
+- **Exact image matching**: Finds the clicked image within the constructed collection by URI first, then falls back to byte equality when needed.
+
+### DOM & rendering
+
+- **DOM construction**: Uses the `h()` helper from `vs/base/browser/dom` with `@name` references for declarative DOM — no imperative `document.createElement` calls.
+- **Bottom bar**: Caption and thumbnail sections are wrapped in a `div.bottom-bar` flex column below the image area.
+- **Stable DOM skeleton**: Builds DOM once per `setInput()`, updates only changing parts to avoid flash on navigation.
+- **Blob URL lifecycle**: Main image URLs tracked in `_imageDisposables` (revoked on nav), thumbnails in `_contentDisposables` (revoked on `clearInput()`).
+- **Focus border suppressed**: The slideshow container uses `outline: none !important` on `:focus` / `:focus-visible` to override the workbench's global `[tabindex="0"]` focus styles.
+
+### Keyboard & focus
+
+- **Keyboard parity**: Uses `registerOpenEditorListeners` (click, double-click, Enter, Space) matching other attachment widgets.
+- **Arrow key navigation**: Handled via DOM `keydown` listener with `stopPropagation()` — not Action2 keybindings, because the modal editor's `KEY_DOWN` handler blocks `workbench.*` commands not in its allowlist. The editor overrides `focus()` to forward focus to the slideshow container so arrow keys work immediately without clicking.
+
+### Zoom
+
+Zoom state is `ZoomScale = number | 'fit'` held in `_zoomScale`.
+
+| Gesture | Effect |
+|---------|--------|
+| Click | Zoom in one level |
+| Alt+click (Mac) / Ctrl+click (Win/Linux) | Zoom out one level |
+| Ctrl+scroll (Win/Linux) or Alt+scroll (Mac) | Continuous zoom (~7.5% per tick) |
+| Trackpad pinch | Zoom (reported as `wheel` + `e.ctrlKey`) |
+
+Predefined zoom levels: 10%, 20%, 30%, …, 100%, 150%, 200%, 300%, 500%, 700%, 1000%, 1500%, 2000%. Click cycles through these levels.
+
+`_applyZoom(scale)` is the central method:
+- `'fit'` → adds `scale-to-fit` class, clears `img.style.zoom`, removes `.zoomed` from container
+- numeric → sets `img.style.zoom`, adds `.zoomed` on the container (enabling `overflow: auto` for panning with themed scrollbars), preserves scroll center using `dx/dy` ratio math, adds `pixelated` class at ≥ 3× zoom
+
+Zoom always resets to `'fit'` when navigating to a different image.
+
+Cursor changes to `zoom-out` when the zoom-out modifier key is held (via `.zoom-out` class on the container).
