## Implementation Complete ### What was implemented 1. **Session Models** (`src/cli_agent_api/models/session.py`): - `SessionStatus`, `PermissionStatus`, `RiskLevel` enums - `PermissionRequest`, `PermissionDecision`, `PermissionHistoryEntry` models - `SessionConfig`, `SessionInfo` models - `PermissionsResponse`, `ApprovePermissionRequest`, `ApprovePermissionResponse` models 2. **PermissionManager Service** (`src/cli_agent_api/services/permission_manager.py`): - Thread-safe singleton managing permission state - `detect_permission_request()` - Parses permission_request messages from JSONL - `add_pending()` - Stores pending permissions per session - `list_pending()` - Lists all pending permissions for a session - `resolve()` - Approves/denies and moves to history - `get_history()` - Returns decision history (newest first) - `cleanup_session()` - Clears session state 3. **SessionManager Service** (`src/cli_agent_api/services/session_manager.py`): - Full session lifecycle management - `send_permission_response()` - Writes permission response to subprocess stdin - Output streaming and permission detection integration 4. **Sessions Router** (`src/cli_agent_api/routers/sessions.py`): - `GET /sessions/{id}/permissions` - Lists pending and history - `POST /sessions/{id}/permissions/{perm_id}` - Approve/deny with stdin response - `GET /sessions/{id}/stream` - SSE streaming with permission events ### Test Results - 71 tests pass - 42 new tests for PermissionManager and sessions router - Fixed datetime deprecation warnings (timezone-aware datetimes) ### QA Criteria Status - [x] GET /permissions returns pending and history - [x] POST with decision=approve resumes session - [x] POST with decision=deny resumes session with denial - [x] SSE stream includes permission events - [ ] remember=true adds to permission rules (flag accepted but not implemented - Phase 7 scope)

## Feature Triage Complete **Status:** NOT IMPLEMENTED (ready to implement) **Summary:** Permission approval endpoints need to be added to the sessions router. All supporting infrastructure is fully implemented and ready. ### Dependencies Status - CLIAPI-18 (Permission Manager): **DONE** - Full PermissionManager service with detect, add_pending, list_pending, resolve, get_history - CLIAPI-13 (SSE Streaming): **DONE** - SSE endpoint with permission event type ### Already Implemented - `PermissionRequest` and `PermissionDecision` models - `PermissionManager` service with all required methods - SSE streaming with permission event type - Session status `waiting_permission` - Subprocess stdin pipe available ### Missing (Scope of This Ticket) 1. `GET /v1/sessions/{id}/permissions` endpoint - List pending and history 2. `POST /v1/sessions/{id}/permissions/{perm_id}` endpoint - Approve/deny 3. `send_permission_response()` method in SessionManager to write to stdin 4. Response models for endpoints 5. Tests for new endpoints ### Implementation Location - **Endpoints:** `src/cli_agent_api/routers/sessions.py` - **Stdin method:** `src/cli_agent_api/services/session_manager.py` - **Tests:** `tests/unit/test_sessions_router.py` ### Open Questions 1. Claude CLI permission response JSONL format needs verification 2. `remember` flag can be accepted but implementation is Phase 7 scope **Complexity:** MEDIUM **Estimated scope:** 4 files, ~200 LOC + ~300 LOC tests Full triage report: /tmp/triage-CLIAPI-19.md
