- "Tailwind motion-safe: prefix for reduced-motion accessibility"
- "CSS variable tokens (bg-card, border-border, text-muted-foreground) for theme compatibility"

modified:
- ui/src/components/ChatMessageList.tsx
decisions:
- "Used @/lib/router Link (not react-router-dom) — consistent with project router abstraction pattern"
- "useBrainstormerDefault uses Agent type from @paperclipai/shared for type-safe sort comparator"
- "ChatSpecCardInner extracted as inner component to avoid conditional hook calls after JSON.parse error path"

# Phase 23 Plan 02: UI Components for Brainstormer Flow Summary
**One-liner:** Five new UI components — spec card with edit mode, handoff separator, task badge, status badge, and general-agent selector hook — using CSS variables and motion-safe animations.
## Tasks Completed
| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | ChatSpecCard and ChatHandoffIndicator components | 1489e499 | ChatSpecCard.tsx, ChatHandoffIndicator.tsx |
| 2 | ChatTaskCreatedBadge, ChatStatusUpdateBadge, useBrainstormerDefault | 651864ba | ChatTaskCreatedBadge.tsx, ChatStatusUpdateBadge.tsx, useBrainstormerDefault.ts, ChatMessageList.tsx (fix) |
## Verification
- `pnpm exec tsc --noEmit -p ui/tsconfig.json` — PASS (clean, no errors)
- Existing test suite — pre-existing failures in server tests (skill-registry-routes, app-hmr-port, plugin-worker-manager, company-import-export-e2e) are unrelated to UI changes introduced here
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Fixed missing messageType in ChatMessageList synthetic streaming entry**
- **Found during:** Task 2 TypeScript check
- **Issue:** `ChatMessage` shared type now requires `messageType: string | null` (added in Plan 23-00 DB migration), but the synthetic streaming entry object in `ChatMessageList.tsx` was missing this field, causing TS2322 type error
- **Fix:** Added `messageType: null` to the synthetic streaming entry object
- **Files modified:** `ui/src/components/ChatMessageList.tsx`
- **Commit:** 651864ba
**2. [Rule 2 - Pattern] Used project router abstraction instead of react-router-dom**
- **Found during:** Task 2 — plan said `import { Link } from "react-router-dom"` but project uses `@/lib/router` wrapper
- **Fix:** Used `import { Link } from "@/lib/router"` consistent with all other components in the codebase
- **Files modified:** `ui/src/components/ChatTaskCreatedBadge.tsx`, `ui/src/components/ChatStatusUpdateBadge.tsx`
## Known Stubs
None — all components have complete implementations. No data stubbed or hardcoded placeholder content that blocks plan goals.
## Self-Check: PASSED
