What problem does it solve? Planning documents often bloat into implementation contracts full of code details, or get reviewed for perfection instead of actual feasibility. This Skill keeps plans lightweight and direction-focused, and reviews them against a single question: will starting now hit a blocker? ## Core Features & Use Cases - Write Mode: Creates a plan file at docs/plans/YYYY-MM-DD-<topic>-plan.md covering goal, scope, ordered steps, risks, and open items, while hard-blocking code blocks, function signatures, and pinned file paths. - Automatic Independent Review: After saving, dispatches a general-purpose subagent that reads only the plan file and reports doubts with a verdict (green/yellow/red), with a local fallback review when no agent tool exists. - Review Mode: On user request, reviews a specified plan file or the most recent one in docs/plans/ using the same stateless checklist and verdict rules. - Use Case: Before starting a multi-step refactor, ask for a plan; the Skill drafts a one-page direction document, then an independent reviewer flags a missing dependency in step order so you fix it before writing any code. ## Quick Start Ask the assistant to write a plan for your upcoming task, for example by saying "plan 써줘" or "write a plan for migrating the auth module".
