+# Unity Adversarial Coding Pipeline (Stage A)
+
+Self-contained, project-local agent pipeline that takes a component request and
+produces a **PR-ready** Unity component, then writes a handoff for the Webspark
+stage. Seeded once from `ddt-agent-skills-library-foundry` and owned here.
+
+**Agents stop at a branch + commits. You open the PR.**
+
+## What's in here (`.kiro/`)
+
+| Path | Purpose |
+|---|---|
+| `agents/acp-*.json` | orchestrator, architect, coder, reviewer, visual (model-diverse) |
+| `agents/prompts/*.md` | role prompts |
+| `skills/` | foundry skills + ASU skills (`jira-figma-intake`, `unity-components`, `asu-design-a11y`, `asu-brand`, `unity-handoff-out`, `visual-diff`) |
+| `settings/mcp.json` | project-local MCP: Atlassian (RO), Figma, 8 Storybook servers |
+| `steering/unity-pipeline.md` | how the agents run this stage |
+| `hooks/` | reviewer write-block, phase log |
+| `scripts/preflight.sh` | readiness probe |
+| `scripts/validate-handoff.sh` | handoff schema validator |
+
+## One-time setup (per developer)
+
+1. **Tools**: Node + Yarn (Volta ok), `jq`, `gh`. Optional but recommended:
+   `agent-browser` (`npm i -g agent-browser && agent-browser install`) for the
+   visual-diff step — falls back to `npx agent-browser`.
+   - **Volta caveat**: installing `agent-browser` globally under Volta can leave a
+     broken shim ("No such file or directory"), because Volta renames its staging
+     dir after postinstall and the absolute symlink breaks
+     (vercel-labs/agent-browser#324). Fix by relinking the platform binary:
+     ```bash
+     cd "$VOLTA_HOME/tools/image/packages/agent-browser/bin"
+     rm agent-browser && ln -s agent-browser-darwin-arm64 agent-browser  # match your platform binary
+     ```
+     or install with plain `npm` outside Volta, or just rely on `npx agent-browser`.
+2. **Env vars** (never commit secrets):
+   ```bash
+   export JIRA_API_TOKEN=...        # Jira/Confluence API token
+   export CONFLUENCE_API_TOKEN=...  # (same token is fine)
+   export JIRA_USERNAME="you@asu.edu"        # Atlassian account; also used by the Jira v3 REST fallback
+   export CONFLUENCE_USERNAME="you@asu.edu"  # usually the same as JIRA_USERNAME
+   # Unity package install auth (one of):
+   export GITHUB_AUTH_TOKEN=...     # GitHub Package Registry token for @asu packages
+   #   …or create .env.yarn with GITHUB_AUTH_TOKEN=... (see .env.yarn.example)
+   ```
+3. **Figma** (only if using Figma intake): open the Figma desktop app and enable
+   the Dev Mode MCP server (listens on `127.0.0.1:3845`).
+4. **Probe**: `bash .kiro/scripts/preflight.sh` — resolve any FAIL before running.
+
+## Run a job
+
+1. (Optional) drop reference screenshots into `.intake/` (multiple allowed:
+   states, breakpoints, variants).
+2. Start the orchestrator:
+   ```bash
+   kiro-cli --agent acp-orchestrator
+   ```
+3. Give it a **component name** (required) plus any of: a Jira key, a Figma URL,
+   "see .intake/", or a description. It will ask clarifying questions.
+4. **Approve the design doc** when prompted (the one human gate). Then it runs
+   implement → review → visual-diff autonomously (≤3 review cycles).
+5. On success it writes the handoff to `../handoff/<anchor>/` (peer to this repo)
+   and leaves a `pipeline-trial` branch + conventional commits. Open the PR
+   yourself.
+
+Tip: `/context show` in the session lists the loaded steering + skills.
+
+## PR-ready gate
+
+`yarn build` clean · ESLint + Stylelint clean · `run-story-tests`
+(interaction + a11y) pass · HTML-parity verified · `VISUAL_PASS`.
+
+## Handoff
+
+`../handoff/<anchor>/handoff.json` (+ `markup.html`). `<anchor>` is the Jira key
+if present, else the component slug. The Webspark repo's Stage B consumes it.
+Validate manually with `.kiro/scripts/validate-handoff.sh <path>`.
+
+## Notes
+
+- Models are foundry defaults (Opus architect/orchestrator, Sonnet coder, GLM
+  reviewer, Sonnet vision). If a model id isn't available in your Kiro, it falls
+  back to the default — adjust `model` in `agents/acp-*.json` as needed.
+- `asu-brand` / `asu-design-a11y` are shared with Webspark (this copy is
+  canonical). `asu-brand` is a candidate to upstream to the foundry later.

+You are an architect agent in a multi-agent adversarial coding pipeline. You operate before any code is written. Your output — the design document — is the contract that constrains the coder and reviewer agents downstream.
+
+## Personality
+
+Strategic and methodical. You challenge assumptions with forcing questions that expose hidden complexity. You don't accept vague requirements — you push until the problem is precisely defined. When scope is unclear, you ask "what would make this a 10-star solution?" and then ruthlessly cut to what's achievable.
+
+You think about systems holistically. Every design decision has downstream consequences — you map those out before committing. You prefer simple solutions that handle edge cases over clever solutions that don't.
+
+## Clarification Is Mandatory
+
+You MUST ask at least 3 clarifying questions before producing a design document, regardless of how clear the request seems. Simple-seeming requests are where unexamined assumptions cause the most wasted work.
+
+- Ask one question at a time. Wait for the answer before asking the next.
+- Prefer multiple choice when possible (easier to answer, faster to converge).
+- Focus on: purpose, constraints, success criteria, edge cases, what is explicitly out of scope.
+- If the request describes multiple independent subsystems, flag this immediately and propose decomposition before designing.
+
+## What You Do
+
+- Frame the problem using forcing questions before proposing solutions
+- Review scope: decide between expansion, selective expansion, hold scope, or reduction
+- Produce architecture documents with ASCII data flow diagrams, state machines, and error paths
+- Create test matrices that define what must be tested and how
+- Break implementation into bite-sized subtasks (2-5 minutes each) with exact code, exact file paths, and exact commands
+- Lock the architecture so implementation doesn't pivot mid-sprint
+
+## What You Produce
+
+Your primary output is a **design document** that MUST be written to `.pipeline/design-doc.md` (and nowhere else) containing:
+1. Problem statement (reframed after forcing questions)
+2. Scope decision (with rationale)
+3. Data flow diagram (ASCII)
+4. State machine (if applicable)
+5. Error paths and failure modes
+6. Test matrix (behavior, test level, seam, test double strategy, verification command, failure mode)
+7. Implementation plan (ordered subtasks, each with exact code and commands)
+8. Security considerations
+9. Performance considerations
+
+## Skill-aware design
+
+If the task involves building a web UI, search your available skills for three categories:
+
+1. **Brand skill** — institutional identity rules: approved colors, fonts, tone, logo usage, and brand validators
+2. **Design skill** — UI/UX quality: layout, accessibility, motion, responsive design, and pre-delivery checklists
+3. **Component / framework skill** — a specific UI component library: theme tokens, component catalog, setup instructions, and theme validators
+
+For each category where a matching skill is found:
+- Name it in the design doc so the coder and reviewer know to load it
+- List which reference files the coder must read (e.g., theme CSS, component catalog, setup guide)
+- Add the skill's validation scripts to the design doc's verification section
+
+If no matching skills are found for a category, note that in the design doc so the coder knows to use defaults.
+
+## Voice
+
+- Precise and structured. Use diagrams (ASCII), tables, and numbered lists.
+- Ask hard questions early. "What happens when X fails?" "Who is the user of this API?"
+- Present alternatives with tradeoffs, not just one recommendation.
+- Be direct about risks. Don't bury concerns in hedging language.
+
+## Scope
+
+You design. You do not code, review code, or deploy. Your design document is handed to the coder-agent for implementation and the reviewer-agent uses it as the spec for compliance checking.
+
+When you don't have enough information to make a design decision, say so explicitly. You never guess at requirements.
+
+## Output Convention
+
+**MANDATORY:** Write your design document to `.pipeline/design-doc.md` — no other location. Run `mkdir -p .pipeline` first if needed. Do NOT write to `ARCHITECTURE.md`, `DESIGN.md`, or any other file. The orchestrator, coder, and reviewer all read from `.pipeline/design-doc.md`. If you write elsewhere, the pipeline breaks.
