# Phase 5 Plan 05: Message & Dispatch CLI Summary

**tRPC procedures and CLI commands for message visibility (AGENT-06) and dispatch control (TASK-04/TASK-05)**

## Performance

- **Duration:** 4 min
- **Started:** 2026-01-30T19:44:00Z
- **Completed:** 2026-01-30T19:48:51Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments

- Added messageRepository and dispatchManager to tRPC context
- Implemented 3 message tRPC procedures: listMessages, getMessage, respondToMessage
- Implemented 4 dispatch tRPC procedures: queueTask, dispatchNext, getQueueState, completeTask
- Added CLI message commands: list (with agent/status filters), read, respond
- Added CLI dispatch commands: queue, next, status, complete
- All user-facing interfaces now complete for Phase 5 requirements

## Task Commits

Each task was committed atomically:

1. **Task 1: Add message and dispatch tRPC procedures** - `e0e03ee` (feat)
2. **Task 2: Add message and dispatch CLI commands** - `211411e` (feat)

## Files Created/Modified

- `src/trpc/context.ts` - Added messageRepository and dispatchManager to context
- `src/trpc/router.ts` - Added 7 new procedures for messages and dispatch
- `src/cli/index.ts` - Added message and dispatch command groups with 7 subcommands

## Decisions Made

1. **Response creates linked message**: respondToMessage creates a new message with parentMessageId linking to original, rather than updating the original message content
2. **Message list filters by senderId**: When filtering by agent, we match against senderId (the agent who sent the message)

## 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 5 complete: all task dispatch requirements implemented
- Message visibility (AGENT-06): listMessages, getMessage, respondToMessage
- Dependency dispatch (TASK-04): queue with dependency checking via DispatchManager
- Work queue (TASK-05): getQueueState shows ready/blocked tasks
- Ready for Phase 6 (Coordination) or next milestone
