Inline comments:
In `@app/api/subagents/`[subagentId]/cancel/route.ts:
- Around line 33-45: The subagent routes incorrectly map authentication and
downstream service failures to 404. In
app/api/subagents/[subagentId]/cancel/route.ts lines 33-45, narrow the 404
handling to getOwnedSubagent only; allow cancelAgentTriggerRun or
cancelSubagentForUser failures to return 5xx. In
app/api/subagents/[subagentId]/token/route.ts lines 45-47, likewise isolate
getOwnedSubagent for 404, let getUserID failures surface as 401, and return 5xx
for auth.createPublicToken failures.
In `@app/components/SubagentsSidebar.tsx`:
- Around line 401-405: Update the empty-state copy in the validation section of
SubagentsSidebar, replacing the internal “child,” “durable run,” and “reserved”
terminology with plain user-facing language that explains the validation will
appear once it starts.
- Around line 300-312: Update the selectedOpenedAt tracking in the useEffect
around selectedOpenedAt and selected so the timestamp is written only when
selected.subagent_id changes, not whenever the selected object is refreshed.
Preserve the existing openedChildren and subagent_opened event behavior while
ensuring subagent_abandoned uses the original user-open timestamp.
- Around line 333-348: Update cancelSelected so the cancel fetch uses an
AbortController timeout matching the route budget, passing its signal in the
POST request and ensuring the controller is cleaned up when the request
completes or fails. Preserve the existing error state and finally block so a
timeout releases canceling and allows retry.
- Around line 269-271: Move the selectedForCleanup.current assignment out of the
render path in SubagentsSidebar and into an effect that depends on selected.
Preserve the existing selected lookup and ensure unmount cleanup reads the last
committed selected child.
In `@app/share/`[shareId]/components/SharedMessagePartHandler.tsx:
- Around line 154-170: Update the tool-delegate_task rendering in
SharedMessagePartHandler so a part with output.status other than "completed" or
with part.errorText renders the action "Validation failed" before evaluating
verdict. Preserve the existing verdict-based labels for successful tasks and the
default "Independent validation" fallback otherwise.
In `@convex/chats.ts`:
- Around line 253-282: The deleteSubagentDataForChat flow must cancel and await
every child run’s trigger_run_id before deleting its subagent_messages and
subagent_runs records. Reuse the existing Trigger cancellation mechanism, handle
queued and running children, and only delete each child after cancellation
completes so active child runs cannot later call finishForBackend against
missing rows.
In `@convex/subagents.ts`:
- Around line 489-508: Update the ctx.db.patch call in the finalization flow to
preserve the existing failure_reason, verdict, confidence, structured_result,
and completed_at values when isCanceledUsageFinalization is true, while
retaining the incoming arguments for normal finalization. Follow the existing
preservation pattern used for summary, failure_code, and cancel_reason.
- Around line 336-346: The subagentTask flow must stop after
attachSubagentTriggerRun when the task is terminal. Capture and inspect the
attach result or re-read the row after attachment, and return without setup or
model execution if its status is canceled or otherwise terminal; preserve the
existing handling for not_found, stale, and active rows.
In `@lib/ai/tools/delegate-task.ts`:
- Around line 220-242: The delegate-task flow around subagentTask.triggerAndWait
must prevent concurrent waits within one parent run. Replace the individual wait
with batchTriggerAndWait or serialize these calls using a run-scoped mutex,
while preserving the existing idempotency key, tags, metadata, and result
handling.
In `@lib/ai/tools/run-terminal-cmd.ts`:
- Line 1086: Update the calls to saveTruncatedOutput in the terminal command
flow, including the locations near the ptyScopeId references, to pass chatId for
output storage instead of ptyScopeId. Preserve ptyScopeId for PTY operations and
apply this change at both affected call sites.
In `@lib/posthog/server.ts`:
- Around line 15-26: Update getPostHogFeatureFlagForUser to ensure feature-flag
lookups fail fast instead of waiting for the posthog-node default 3-second
timeout. Configure the PostHog client or getFeatureFlag call with a shorter
explicit featureFlagsRequestTimeoutMs, while preserving the existing false
fallback for unavailable clients and lookup errors.
In `@trigger/agent-long.ts`:
- Around line 1638-1660: Bound the child-cancellation section in onCancel with a
short Promise.race deadline, including the active-child lookup,
cancelAgentTriggerRun calls, and cancelSubagentsForParent persistence. Preserve
the existing warning behavior for individual failures and ensure a timeout
allows onCancel to continue to ptySessionManager.closeAll and phLogger.flush,
following the existing runPromise timeout pattern.
In `@trigger/subagent.ts`:
- Around line 183-203: Move the subagent setup flow beginning with getSubagent
through attachSubagentTriggerRun, tags.add, and metadata.set inside the existing
try block, or otherwise ensure every setup failure writes a terminal status via
finishSubagent before rethrowing. Also delete the cancellationCleanup entry when
setup fails after it is populated, including unsupported profile/depth and
attachment or metadata errors, while preserving normal cancellation and
execution behavior.
- Around line 566-591: Update the catch path around finishSubagent to classify
aborts using the same precedence as the success-path ladder: preserve
parent/user cancellation, then classify activeTimedOut as timed_out and
spendCapExceeded as spend_cap before falling back to runtime_error. Derive
status, failureCode, and the summary from that shared classification so
active-timeout and spend-cap aborts are recorded consistently.

Inline comments:
In `@app/components/MessagePartHandler.tsx`:
- Around line 241-248: Update arePropsEqual for the subagent tool cases to
detect newly added matching data-subagent-lifecycle entries in message.parts,
even when the tool-part object is unchanged. Return false when lifecycle data
changes or arrives so SubagentToolHandler re-renders and displays the lifecycle
name, while preserving equality for unchanged lifecycle state.
In `@app/components/SubagentsSidebar.tsx`:
- Around line 568-592: The cleanup in the effect tracking
effectiveParentMessageId incorrectly emits subagent_abandoned when that
dependency changes. Keep subagent_sidebar_opened tied to selectedOriginResolved
and effectiveParentMessageId, but move the abandonment cleanup using
selectedForCleanup.current into a separate mount-only effect so it runs only on
component unmount.
- Line 544: Update the now state initialization in SubagentsSidebar to use a
lazy useState initializer, ensuring Date.now() executes only during initial
state creation while preserving the existing initial timestamp value.
In `@app/components/tools/SubagentToolHandler.tsx`:
- Around line 117-128: The assignVisualIndexes function can loop forever when
presentations exceed SUBAGENT_VISUALS.length; bound probing to that length and
fall back to the original modulo index when all visuals are occupied. In
app/components/tools/__tests__/SubagentToolHandler.test.tsx lines 208-279, add a
SubagentToolGroup case with seven successful tool-create_agent parts and assert
all seven chips render. In app/components/worked-for-parts.ts lines 121-160, no
direct change is required unless duplicate visuals in one row are unacceptable;
otherwise optionally cap groupAdjacentSubagentActivities runs to split oversized
groups into multiple rows.
- Around line 303-311: Update the sidebarContent useMemo dependencies in both
SubagentFallback and SubagentChip to use the content object’s primitive fields
rather than presentation.sidebarContent itself, and construct the memoized value
from those fields. Keep the useToolSidebar integration unchanged so sidebar
content remains referentially stable across renders.
In `@app/share/`[shareId]/components/SharedMessagePartHandler.tsx:
- Around line 166-183: Update the `tool-create_agent` and
`tool-send_message_to_agent` branches in `SharedMessagePartHandler` so their
failure checks treat a truthy `part.errorText` the same as `part.output?.success
=== false`. Preserve the existing success actions and use the combined failure
condition when selecting each `ToolBlock` action.
In `@lib/ai/subagents/__tests__/runtime-contracts.test.ts`:
- Around line 36-39: Update the marker-based assertions in the runtime contract
tests around the ordering checks and chats cleanup slice: store each indexOf
result, assert every marker index is non-negative before comparing or slicing,
then preserve the existing ordering and .collect() expectations.
In `@lib/ai/subagents/contracts.ts`:
- Around line 161-188: Update the structured recovery handling for
securityValidationResultSchema so its recovery message explicitly requires
confirmed results to include at least one reproduction step and one evidence
reference, matching the superRefine rule. Alternatively, encode this conditional
requirement in the generation schema so invalid confirmed outputs are rejected
before recovery; preserve the existing single recovery budget.
In `@lib/ai/tools/subagent-tools.ts`:
- Around line 65-88: Update resultFromRecord to handle malformed persisted
structured_result and unconstrained summary values without throwing during
wait_for_agents. Normalize or validate bounded fields before constructing the
result, and use agentValidationResultSchema.safeParse with a minimal valid
fallback when parsing fails; preserve valid terminal status and available
evidence where possible.

Local development and Vercel Preview are enabled without a flag. Production fails closed until the PostHog flag is configured. Start with an internal allowlist, emit exposure only when the feature is actually available, and record the owner, guardrails, rollback threshold, readout date, and cleanup plan before ramping.
