# Phase 19 Plan 01: Backend API for Agent Questions Summary

**Two tRPC procedures (getAgentQuestions, listWaitingAgents) and shared PendingQuestions/QuestionItem type exports for frontend inbox**

## Performance

- **Duration:** 3 min
- **Started:** 2026-02-04
- **Completed:** 2026-02-04
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments
- Added `getAgentQuestions` procedure exposing structured question data from AgentManager
- Added `listWaitingAgents` procedure filtering to `waiting_for_input` status
- Exported `PendingQuestions` and `QuestionItem` types from `@codewalk-district/shared`

## Task Commits

Each task was committed atomically:

1. **Task 1: Add getAgentQuestions and listWaitingAgents tRPC procedures** - `004140e` (feat)
2. **Task 2: Export PendingQuestions and QuestionItem from shared package** - `47a2bb3` (feat)

## Files Created/Modified
- `src/trpc/router.ts` - Added getAgentQuestions and listWaitingAgents procedures, updated JSDoc
- `packages/shared/src/types.ts` - Re-export PendingQuestions and QuestionItem from agent types
- `packages/shared/src/index.ts` - Added PendingQuestions and QuestionItem to public exports

## Decisions Made
- Re-export from `../../../src/agent/types.js` works because shared tsconfig has `rootDir: "../.."`
- `listWaitingAgents` filters `agentManager.list()` in-memory rather than adding a new DB query (agents are in-memory anyway)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

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

## Next Phase Readiness
- Both procedures available for frontend consumption via tRPC client
- Shared types ready for import in inbox components
- Ready for 19-02-PLAN.md (InboxList & MessageCard Components)
