# Tech tracking
tech-stack:
  added: []
  patterns:
    - Real CLI integration tests skipped by default (env var to enable)
    - structured_output field for JSON schema responses

key-files:
  created:
    - src/test/integration/real-claude.test.ts
  modified:
    - src/agent/manager.ts

key-decisions:
  - "Use structured_output field (not result) when --json-schema is used"
  - "Integration tests skipped by default (REAL_CLAUDE_TESTS=1 to enable)"
  - "Test timeout of 120s for real API calls"

patterns-established:
  - "Real CLI integration tests as validation tool, not CI suite"

# Phase 13 Plan 01: Real Claude CLI Integration Tests Summary

**Integration tests for validating JSON schemas with real Claude CLI, discovered result field is empty when using --json-schema (structured_output contains data)**

## Performance

- **Duration:** 4 min
- **Started:** 2026-02-02T09:36:37Z
- **Completed:** 2026-02-02T09:40:10Z
- **Tasks:** 3
- **Files modified:** 2

## Accomplishments

- Created integration test suite for all agent modes (execute, discuss, breakdown, decompose)
- Fixed ClaudeAgentManager to correctly read from `structured_output` field
- Documented actual Claude CLI response structure with `--json-schema` flag
- Validated MockAgentManager accurately simulates real CLI behavior

## Task Commits

Each task was committed atomically:

1. **Task 1: Create real Claude CLI integration test file** - `3c98dbe` (test)
2. **Task 2: Fix ClaudeAgentManager to parse structured_output** - `5605547` (fix)
3. **Task 3: Run real Claude tests and document findings** - `accbaca` (docs)

## Files Created/Modified

- `src/test/integration/real-claude.test.ts` - Integration tests for all agent mode schemas
- `src/agent/manager.ts` - Added `structured_output` field to ClaudeCliResult, fixed parsing

## Decisions Made

1. **Use `structured_output` field for JSON schema responses** - When using `--json-schema` flag, Claude CLI returns structured data in `structured_output` field, not `result`. The `result` field is empty in this case.

2. **Integration tests skipped by default** - Tests call real Claude API and incur costs (~$0.025 per call). Enable with `REAL_CLAUDE_TESTS=1` environment variable.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## Key Finding: Claude CLI Response Structure

When using `--json-schema` flag:
```json
{
  "type": "result",
  "subtype": "success",
  "result": "",                        // EMPTY
  "structured_output": { ... },        // Actual validated JSON here
  "session_id": "...",
  "total_cost_usd": 0.025
}
```

This is different from non-schema mode where `result` contains the text response.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Integration tests in place for schema validation
- ClaudeAgentManager correctly handles structured_output
- Ready to use real CLI tests for future schema changes
