# Dependency graph
requires:
  - phase: 11-03
    provides: Mode-aware agent spawning, mode-specific completion handlers
  - phase: 11-04
    provides: Initiative and Phase tRPC procedures, repository context injection
provides:
  - Comprehensive mode-specific agent prompts module
  - spawnAgent procedure accepts mode parameter
  - spawnArchitectDiscuss procedure for context gathering
  - spawnArchitectBreakdown procedure for phase decomposition
affects: [11-06, 11-07, 11-08, cli-commands]

# Phase 11 Plan 05: Agent Prompts Module Summary

**Comprehensive mode-specific agent prompts with architect spawn procedures for discuss and breakdown modes**

## Performance

- **Duration:** 2 min
- **Started:** 2026-01-31T18:14:36Z
- **Completed:** 2026-01-31T18:16:56Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments

- Created prompts module with buildDiscussPrompt, buildBreakdownPrompt, buildExecutePrompt
- Updated spawnAgent procedure to accept mode parameter
- Added spawnArchitectDiscuss procedure for context-gathering mode
- Added spawnArchitectBreakdown procedure for phase decomposition mode

## Task Commits

Each task was committed atomically:

1. **Task 1: Update spawnAgent to support mode** - `4843b95` (feat)
2. **Task 2: Create comprehensive agent prompts module** - `773f6f9` (feat)
3. **Task 3: Add spawnArchitect tRPC procedures** - `c139859` (feat)

## Files Created/Modified

- `src/agent/prompts.ts` - Comprehensive prompts for discuss, breakdown, and execute modes
- `src/agent/index.ts` - Export prompts from module index
- `src/trpc/router.ts` - Mode param on spawnAgent, architect spawn procedures

## Decisions Made

1. **Prompts in dedicated module** - Separate file for reusability across manager implementations
2. **buildExecutePrompt takes task description** - Worker agents work on tasks, not initiatives
3. **Architect spawn validates initiative** - Prevents orphaned agents with missing initiative

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Agent prompts module ready for use by CLI commands
- Architect spawn procedures available via tRPC
- Ready for 11-06 (Architect CLI Commands) or 11-07 (E2E Tests)
