## Code Review: PR #88 - Add list_agent_logs MCP Tool ### Summary: **PASS AUDIT** ✅ All acceptance criteria met. Implementation is comprehensive, well-tested, and follows existing patterns. --- ### Acceptance Criteria Status | Criterion | Status | Evidence | |-----------|--------|----------| | New MCP tool `list_agent_logs` exists | ✅ PASS | Tool definition added at line 355 | | Supports filtering by agent_id, ticket_id, status, date range | ✅ PASS | All filters implemented in handler | | Supports pagination (limit, offset) | ✅ PASS | Limit/offset with defaults (50/0) | | Supports sorting (created_at, duration_ms) | ✅ PASS | Sort by with asc/desc options | | Tool available to orchestrator and researcher | ✅ PASS | Added to `session_tools` permission group | | Returns structured log data | ✅ PASS | Response includes action, status, duration_ms, details | --- ### Changes Reviewed **1. `app/controllers/api/v1/mcp_controller.rb`** - Lines 355-376: New tool definition `list_agent_logs` with comprehensive parameters - Lines 1072-1148: Handler `handle_list_agent_logs` with full implementation: - Project-scoped query (prevents cross-project access) - Filter by agent_id, ticket_id, status, action - Date range filtering with error handling - Sorting by created_at or duration_ms - Pagination with limit/offset - Rich response with metadata and structured log data **2. `config/tinker/mcp_permissions.yml`** - Added `list_agent_logs` to `session_tools` permission group - Available to orchestrator, researcher, worker, reviewer **3. `spec/requests/api/v1/mcp_spec.rb`** - 16 new test examples covering all features: - Basic listing scoped to project - Filters: agent_id, ticket_id, status, action - Date range filtering (from_date, to_date) - Error handling for invalid dates - Sorting by created_at and duration_ms - Pagination (limit, offset) - Structured data verification - Worker access via session_tools - Error when agent has no project --- ### Quality Assessment **Code Quality:** ✅ EXCELLENT - Follows existing MCP tool patterns - Proper error handling for invalid date formats - Clean parameterized queries (no SQL injection risk) - Rich response structure with metadata (total_count, offset, returned_count, filter) **Security:** ✅ PASS - **Project-scoped query** - Critical security feature preventing cross-project access - Uses parameterized queries throughout - Permission group properly configured - Validates agent has project_id **Test Coverage:** ✅ COMPREHENSIVE - 16 new test examples (PR reports 108 total, 16 new) - Tests cover all filters, sorting, pagination - Edge cases tested (invalid dates, no project, etc.) - Permission tests verify access controls **API Design:** ✅ EXCELLENT - Flexible filtering options - Intuitive pagination (limit + offset) - Sensible defaults (limit: 50, offset: 0, sort_by: created_at desc) - Rich response with filter echo and metadata --- ### Test Results - **MCP specs:** 92 examples passed (on main branch, PR adds 16 more) - **Full suite:** 690 examples, 2 pre-existing failures (unrelated dashboard UI issues) --- ### Implementation Highlights **1. Project Scoping (Security Critical)** ```ruby logs = AgentLog.where(agent_id: Agent.where(project_id: current_agent.project_id).select(:id)) ``` This ensures agents can only view logs from their own project. **2. Rich Response Structure** ```ruby { total_count:, # Total matching records offset:, # Pagination offset used returned_count:, # Number of records returned filter: {...}, # Echo of applied filters logs: [...] # Array of log entries } ``` **3. Error Handling** - Invalid date formats return clear error messages - Agent without project returns meaningful error --- ### Recommendation **PASS AUDIT** - This PR is ready to merge. The implementation is comprehensive, well-tested, secure, and follows all existing patterns. The `list_agent_logs` tool provides valuable functionality for the orchestrator and researcher to view agent activity history.
