- DAG executor: async I/O, code review system, smarter retry and stuck graph detection, improved batch planning - Contracts: simplified failure categories, role type changed to str with runtime validation for plugin extensibility - PM agent: reads codebase directly, architect subprocess removed - Config: tightened agent limits, memory management constants, experimental features disabled by default - Memory: prevent unbounded growth, improved snapshot management - Bug fixes: lazy init escalation tracking, agent runtime SDK signature
- New stats router with project-level analytics - System endpoint improvements for health monitoring - Project stats tracking across sessions - Tests: config validation, health metrics, project stats
Users can create, enable/disable, and delete custom agent roles from the UI or by dropping Python files in the plugins/ directory. - PluginBase ABC with role_name, system_prompt, file_scope, is_writer - PluginRegistry with discovery, hot-reload, enable/disable lifecycle - Security: symlink traversal protection, role name validation, prompt injection sanitization in PM context - API: POST create, DELETE remove, GET list, POST enable/disable - Frontend: PluginsPage with create form, table, and delete - DAG executor and debate engine resolve plugin system prompts - Sample plugin: documentation_writer - 70 tests covering registry, API CRUD, contracts validation
Interactive task graph page using React Flow with live updates and execution replay. - Backend: GET /dag and /dag/history endpoints from checkpoint DB - DagNode component with 7 status styles and animations - BFS layout algorithm for hierarchical positioning - Live polling (3s) during active execution - Replay mode with timeline slider to step through history - Links from ConductorBar and DesktopLayout - 28 tests covering API endpoints and edge cases

Description
Major reliability, performance, and extensibility update. Overhauls the DAG executor with async I/O, smarter
retry/self-healing, and a code review system. Simplifies the agent pipeline by removing the architect subprocess. Adds
a plugin system for custom agent roles and an interactive DAG visualization page. Includes memory management
improvements, frontend fixes, and comprehensive new test coverage.
