--- description: Decompose monolithic plan into parallel task files argument-hint: "[plan-file]" --- Use the decomposing-plans skill to break down a monolithic plan into parallel task files. **Prerequisites:** - Plan file exists: `docs/plans/YYYY-MM-DD-.md` - Plan has 2+ tasks worth decomposing **What this does:** 1. Reads the monolithic plan 2. Identifies parallelizable tasks 3. Creates task files in `docs/plans/tasks/YYYY-MM-DD-/` 4. Generates `manifest.json` with parallel batches 5. Prompts for next step: review or execute **Output:** - Task files: One per task - Manifest: Defines batch execution order - Enables parallel execution (up to 4 tasks per batch) **Recommendation:** Always decompose plans with 4+ tasks for parallel execution. **Next step:** Review plan or execute immediately
