What problem does it solve? Complex tasks often mix expensive high-level reasoning with cheap repetitive execution in a single session, wasting context and making progress hard to track. This Skill separates planning and review from implementation by coordinating an orchestrator with bounded worker sessions. ## Core Features & Use Cases - Orchestrator/Worker Split: An orchestrator plans, delegates, and reviews while each worker executes exactly one bounded task. - File-Based Communication: Coordination happens through .ai/PLAN.md, STATE.md, QUESTIONS.md, and RESULT.md so sessions stay decoupled and auditable. - Codex Session Launching: Workers run as separate Codex sessions via codex exec with a chosen model, with flags verified against codex exec --help. - Use Case: When refactoring a large module, the orchestrator writes a plan, spawns one worker per file or subtask, answers worker questions, and reviews each RESULT.md before marking the plan complete. ## Quick Start Read the orchestrator-worker protocol file and act as the orchestrator to plan this task and delegate bounded subtasks to worker sessions.
