# Dependency graph
requires:
  - phase: 19-agent-inbox
    provides: InboxList, MessageCard, QuestionForm, OptionGroup, FreeTextInput components and tRPC procedures (getAgentQuestions, listWaitingAgents)
  - phase: 18-initiative-detail
    provides: Query management patterns, mutation/invalidation flow, loading/error state patterns
provides:

  - Answer submission flow (QuestionForm → resumeAgent mutation → query invalidation)
  - Notification dismissal flow (respondToMessage mutation)
  - Two-column responsive layout with detail panel
affects: [21-polish-integration]

# Phase 19 Plan 04: Inbox Page Assembly Summary

**Agent Inbox page wired with tRPC data fetching, two-column layout (InboxList + detail panel), answer submission via resumeAgent, and notification dismissal via respondToMessage**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-04
- **Completed:** 2026-02-04
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments
- Replaced stub inbox page with full implementation connecting all Phase 19 components
- Wired InboxList with listWaitingAgents and listMessages tRPC queries
- Detail panel shows agent header, structured QuestionForm, or notification content based on selection
- Answer submission calls resumeAgent mutation and refreshes data on success
- Notification messages can be dismissed via respondToMessage mutation
- Loading and error states handled following initiative detail page patterns

## Task Commits

Each task was committed atomically:

1. **Task 1: Wire inbox page with data fetching, detail panel, and answer submission** - `3cac453` (feat)
2. **Task 2: Full build verification and integration check** - No code changes needed (all checks pass)

## Files Created/Modified
- `packages/web/src/routes/inbox.tsx` - Full inbox page with tRPC queries, mutations, InboxList, QuestionForm, detail panel, loading/error states

## Decisions Made
- Detail panel implemented inline in the page file (not a separate component) since it's page-specific layout
- useUtils() for query invalidation on mutation success, following the same pattern used in initiative detail page
- Agent/message data serialized to string dates before passing to InboxList (wire format consistency with other components)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Phase 19 (Agent Inbox) is complete — all 4 plans executed
- Inbox page fully functional with list view, detail panel, question answering, and notification dismissal
- Ready for Phase 20+ (polish and integration)
