## Code Review: Ticket #94 - Agent Session Logs ✓ PASS ### Summary All acceptance criteria met. Persistent terminal log storage with AgentSession/AgentTerminalLog models, REST API for log ingestion, MCP tools for querying, and 7-day retention cleanup job. ### Acceptance Criteria Verification #### 1. All Terminal Output Stored in Database ✓ **`AgentSession` model** (63 lines): - Fields: agent_id, agent_identifier, started_at, ended_at, status (running/completed/failed), ticket_id - AASM state machine with proper transitions (running → completed/failed) - `has_many :terminal_logs, dependent: :destroy` - Scopes: running, completed, failed, recent, for_agent, for_ticket - `#duration` method calculates session length - `#add_log` helper creates terminal log entries **`AgentTerminalLog` model** (22 lines): - Fields: agent_session_id, timestamp (bigint), output_line (text), line_type (stdout/stderr), ansi (boolean) - Proper validations with inclusion checks - Scopes: chronological, reverse_chronological, with_ansi, stdout, stderr #### 2. Queryable by Agent, Time Range, Ticket ✓ **`AgentSessionsController`** (143 lines): - `POST /api/v1/agent_sessions/start_session` - Creates new session - `POST /api/v1/agent_sessions/:id/ingest` - Batch or single log ingestion - `POST /api/v1/agent_sessions/:id/end_session` - Marks session complete/failed - `GET /api/v1/agent_sessions/:id` - Show session with logs - Internal auth via `X-Terminal-Internal` header - Filters by agent_id, ticket_id, status, date range in `sessions` action #### 3. MCP Tool to Retrieve Historical Logs ✓ **`get_terminal_logs` tool:** - Parameters: agent_id, ticket_id, session_id, status, limit (100), include_session_info - Returns formatted logs with timestamp, line, line_type, ansi - Supports filtering by multiple criteria **`list_agent_sessions` tool:** - Parameters: agent_id, ticket_id, status, limit (20) - Returns session metadata: id, agent_id, status, started_at, ended_at, duration, log_count Both tools registered in `mcp-bridge/src/tools/index.ts` ✓ #### 4. Automatic Cleanup of Old Logs ✓ **`CleanupOldTerminalLogsJob`** (34 lines): - `DEFAULT_RETENTION_DAYS = 7` - Deletes logs older than retention period - Cleans up empty sessions (no logs) - Returns deleted counts for logging - Scheduled daily at 2am in `config/recurring.yml` ### Test Coverage - Model tests: 31 examples, 0 failures ✓ - Factories: agent_sessions.rb, agent_terminal_logs.rb ### Code Quality - Proper foreign key constraints and indexes in migrations - AASM transitions auto-set `ended_at` timestamp - Batch ingestion support for performance - Text type for output_line (no length limit) - BigInt for timestamp (Unix millis) ### No Issues Found No bugs, security issues, or code quality problems. Ready to merge.
