What problem does it solve? It standardizes how implementation plans are created, reviewed, and executed in the GRID Craft Launcher repository, ensuring multi-file changes follow a consistent, verifiable structure. ## Core Features & Use Cases - Plan Trigger Rules: Defines when planning is required (multi-file changes, new modules, launch or download behavior changes) and when to skip it (one-file fixes, test-only changes). - Structured Plan Format: Enforces sections for Summary, Files table, numbered Steps with named agents, Verification, and Risks. - Required Reading: Directs planners to ARCHITECTURE.md, docs/SPEC.md requirement ids, domain skills, and docs/research/ before planning. - Use Case: When adding a new download feature, produce a plan whose steps each name an agent, the files it may touch, the test it runs, and the command proving completion. ## Quick Start Ask the assistant to create an implementation plan for a new launcher feature following the planning skill standards.
