Orchestrate end-to-end feature development from requirements to production deployment:

Backend service development with long connections, multi-language support, and AI agent capabilities. \n \n Supports two modes: Function mode (Node.js, built-in HTTP/WebSocket/SSE, fixed port 3000, local running) and Container mode (any language/runtime via Docker, no local tool support) \n Requires stateless services that listen on the PORT environment variable and write data externally; resource constraints enforce Mem = 2 × CPU \n Includes read tools ( queryCloudRun ) for listing services and

Expert guidance for Godot Engine scene creation, node management, GDScript scripting, and project architecture. \n \n Covers 2D and 3D node types, scene tree hierarchy, physics bodies, collision systems, cameras, UI controls, and animation \n Includes GDScript patterns for node references, lifecycle methods (_ready, _process, _physics_process), and input handling \n Provides project structure best practices and common workflows like character setup, camera configuration, and input management \n

Create and execute plan by dispatching fresh subagent per task or issue, with code and output review after each or batch of tasks.

Dispatch fresh subagents per task with two-stage review (spec compliance, then code quality) in the current session. \n \n Isolates each task to a dedicated subagent with precisely crafted context, preventing context pollution and keeping the controller focused on coordination \n Enforces a two-stage review cycle: spec compliance reviewer confirms the implementation matches requirements, then code quality reviewer checks for issues \n Handles implementer status signals (DONE, DONE_WITH_CONCERNS,
