# Dependency graph
requires:
  - phase: 11-architect-agent
    plan: 01
    provides: AgentMode type, mode-specific output schemas, JSON schemas for Claude CLI
provides:
  - Mode-aware agent spawning via ClaudeAgentManager
  - Mode-specific JSON schema selection for Claude CLI
  - Mode field in CreateAgentData for repository operations
  - Mode-specific completion handlers (execute, discuss, breakdown)
affects: [11-05, 11-06, 11-08]

# Phase 11 Plan 03: Mode-Aware Agent Spawning Summary

**ClaudeAgentManager updated to spawn agents with mode-specific JSON schemas and route completion handling by mode**

## Performance

- **Duration:** 2 min
- **Started:** 2026-01-31T18:10:41Z
- **Completed:** 2026-01-31T18:12:57Z
- **Tasks:** 3 (Task 3 already complete from 11-01)
- **Files modified:** 3

## Accomplishments

- Added mode field to CreateAgentData interface with 'execute' default
- Updated DrizzleAgentRepository.create() to handle mode field
- Added getJsonSchemaForMode() helper for mode-specific schema selection
- Refactored handleAgentCompletion() into mode-specific handler methods
- Updated spawn() to pass mode to repository and use correct JSON schema
- Updated resume() to use mode-specific JSON schema

## Task Commits

Each task was committed atomically:

1. **Task 1: Update AgentRepository for mode field** - `75f8887` (feat)
2. **Task 2: Update ClaudeAgentManager for mode-specific schemas** - `937d24e` (feat)
3. **Task 3: Add mode to AgentStoppedEvent reasons** - Already complete from 11-01

## Files Created/Modified

- `src/db/repositories/agent-repository.ts` - Added AgentMode import and mode field to CreateAgentData
- `src/db/repositories/drizzle/agent.ts` - Updated create() to include mode with 'execute' default
- `src/agent/manager.ts` - Added mode-specific schema imports, getJsonSchemaForMode(), and mode-specific handlers

## Decisions Made

1. **11-03: Mode extracted from options** - Default to 'execute' in spawn() for backwards compatibility
2. **11-03: Separate handler methods per mode** - Clean separation of concerns for execute/discuss/breakdown output parsing
3. **11-03: Resume uses mode-specific schema** - Agent's stored mode determines JSON schema for resumed sessions

## Deviations from Plan

None - plan executed exactly as written. Task 3 was already complete from Plan 11-01.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Mode-aware agent spawning complete and ready for 11-04 (Architect Agent Prompts)
- All existing tests pass (384 tests)
- Build successful with no type errors
- Backwards compatible - default mode='execute' preserves existing behavior
