# Dependency graph
requires:
  - phase: 08.1-agent-output-schema
    provides: discriminated union agent output schema with single question
provides:
  - Multi-question array schema (questions instead of question)
  - QuestionItem type with id for answer matching
  - PendingQuestions interface for array-based questions
  - AgentWaitingEvent with questions array payload
affects: [phase-11-architect-agent, phase-12-phase-task-decomposition]

# Phase 10 Plan 01: Multi-Question Schema Summary

**Extended agent output schema from single question to questions array with id-based answer matching**

## Performance

- **Duration:** 5 min
- **Started:** 2026-01-31T16:52:52Z
- **Completed:** 2026-01-31T16:57:38Z
- **Tasks:** 3
- **Files modified:** 10

## Accomplishments

- Changed agent output schema status from 'question' to 'questions' (plural)
- Added QuestionItem type with unique id field for answer correlation
- Updated PendingQuestions interface to wrap questions array
- Updated AgentWaitingEvent payload to use questions array
- Updated all adapters (ClaudeAgentManager, MockAgentManager) and test infrastructure

## Task Commits

All three tasks were committed atomically since they're interdependent:

1. **Task 1: Update agent output schema** - `151a4c9` (feat)
2. **Task 2: Update PendingQuestion type** - `151a4c9` (feat)
3. **Task 3: Update AgentWaitingEvent payload** - `151a4c9` (feat)

_Note: Single atomic commit because schema/type/event changes require downstream adapter updates to compile_

## Files Created/Modified

- `src/agent/schema.ts` - Added questionItemSchema, changed status to 'questions'
- `src/agent/types.ts` - Added QuestionItem, renamed PendingQuestion to PendingQuestions
- `src/events/types.ts` - Updated AgentWaitingEvent payload to questions array
- `src/agent/manager.ts` - Updated ClaudeAgentManager for new schema
- `src/agent/mock-manager.ts` - Updated MockAgentManager and MockAgentScenario
- `src/test/harness.ts` - Renamed setAgentQuestion to setAgentQuestions
- `src/agent/mock-manager.test.ts` - Updated test scenarios
- `src/dispatch/manager.test.ts` - Updated mock interface
- `src/test/e2e/edge-cases.test.ts` - Updated test scenarios
- `src/test/e2e/recovery-scenarios.test.ts` - Updated test scenarios

## Decisions Made

| Decision | Rationale |
|----------|-----------|
| Status 'questions' (plural) | Clearer than 'question' when payload is array |
| Each question has id field | Enables matching answers to specific questions in batched resume |
| Single question uses array | Consistent API - single question is `questions: [{ id: 'q1', question: '...' }]` |

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Updated downstream adapters and tests**
- **Found during:** Task 1 (Schema changes)
- **Issue:** Schema changes broke type compilation in adapters and tests
- **Fix:** Updated ClaudeAgentManager, MockAgentManager, TestHarness, and all test files
- **Files modified:** manager.ts, mock-manager.ts, harness.ts, 4 test files
- **Verification:** npm run build passes, npm test passes (381 tests)
- **Committed in:** 151a4c9 (combined with schema changes)

---

**Total deviations:** 1 auto-fixed (blocking issue)
**Impact on plan:** Necessary downstream updates for type safety. No scope creep.

## Issues Encountered

None - plan executed with expected downstream cascading updates.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Multi-question schema complete, ready for Phase 11 (Architect Agent)
- Schema supports batching multiple questions in single pause
- Tests verify full question lifecycle with new array structure
