## ✅ QA PASSED - CLIAPI-4 VERIFIED **QA Agent:** code-verification-qa **Date:** 2026-01-03 **Verdict:** VERIFIED - Implementation is production-ready ### Summary All QA criteria met. 131/131 tests passing (including 17 new auth tests). Manual smoke testing confirms correct behavior in production-like conditions. ### Tests Performed ✅ Unit test suite (131 tests, all passing) ✅ Manual smoke test with live server ✅ Valid Bearer token authentication ✅ Invalid token rejection (401) ✅ Missing token rejection (401) ✅ Health endpoint exclusion ✅ Error response format validation ✅ WWW-Authenticate header verification ### QA Criteria Results - ✅ Requests without Authorization header return 401 - ✅ Requests with invalid token return 401 - ✅ Requests with valid Bearer token return 200 - ✅ Error response follows spec format - ✅ /v1/health accessible without auth (when configured) ### Code Quality - Clean, well-documented implementation - Proper use of FastAPI security utilities - Comprehensive test coverage (17 new tests) - No regressions (all existing tests pass) - Security best practices followed ### Detailed Report See `/tmp/qa-CLIAPI-4.md` for complete QA documentation. **Recommendation:** Issue ready for deployment.

## Implementation Complete **Changes made:** 1. **src/cli_agent_api/auth.py** - Implemented `verify_bearer_token` FastAPI dependency: - Uses `HTTPBearer` security scheme with `auto_error=False` to handle missing auth - Returns 401 with spec-compliant error format: `{"error": {"code": "UNAUTHORIZED", "message": "..."}}` - Includes `WWW-Authenticate: Bearer` header on 401 responses - Checks `auth_exclude_health` config to optionally bypass auth for `/v1/health` 2. **src/cli_agent_api/models/config.py** - Added `auth_exclude_health` boolean field to `SecurityConfig`: - Defaults to `True` (health endpoint accessible without auth) - Configurable via `CLI_AGENT_API_SECURITY__AUTH_EXCLUDE_HEALTH` env var 3. **src/cli_agent_api/main.py** - Applied auth dependency to v1 router: - All `/v1/*` endpoints now require authentication when `api_token` is configured - Added `Depends(verify_bearer_token)` to router 4. **tests/unit/test_auth.py** - 17 comprehensive tests covering: - Missing auth header returns 401 - Invalid token returns 401 - Valid Bearer token returns 200 - Error response follows spec format - Health endpoint exclusion works correctly - Auth disabled when no api_token configured **QA Criteria Verified:** - [x] Requests without Authorization header return 401 - [x] Requests with invalid token return 401 - [x] Requests with valid Bearer token return 200 - [x] Error response follows spec format - [x] /v1/health accessible without auth (when configured) **Test results:** All 131 tests passing (17 new auth tests)

## Feature Triage Complete **Status:** NOT IMPLEMENTED **Summary:** Bearer token authentication is not yet implemented. The `auth.py` file exists but is empty (only a docstring). The `SecurityConfig` model already has an `api_token` field ready for use. **Implementation Location:** - Primary: `src/cli_agent_api/auth.py` (implement `verify_bearer_token` dependency) - Updates: `main.py` (apply dependency to protected routers) - Config: `models/config.py` (add `auth_exclude_health` option) - Tests: `tests/unit/test_auth.py` (new) **Complexity:** Low - FastAPI provides built-in `HTTPBearer` security utilities. No new dependencies required. **Estimated scope:** ~50-100 lines of implementation + ~100 lines of tests See attached triage report at `/tmp/triage-CLIAPI-4.md` for full details including implementation approach, edge cases, and testing strategy.
