Refactor Planner

Use this skill for large refactors and migrations where the user wants:

• one stable answer shape every time
• low reading overhead
• route-family-first mapping
• dependency-aware waves
• explicit separation of confirmed facts vs guesses
• tight coordination between mapping, design, execution, and closeout

This skill is especially useful for API-server migrations such as:

• Express -> Hono
• controller style -> Effect services
• untyped handlers -> typed contracts
• mixed legacy runtime -> Effect-first runtime
