Code Refactoring Planner
Analyze a codebase or module and produce a safe refactoring plan with risks, boundaries, tests, migration steps, and acceptance criteria.
Code Refactoring Planner is a free AI skill for code improvement. Analyze a codebase or module and produce a safe refactoring plan with risks, boundaries, tests, migration steps, and acceptance criteria. It works with Claude, ChatGPT, Cursor and is ready to use out of the box.
About this skill
Code Refactoring Planner helps developers improve maintainability without turning cleanup into an uncontrolled rewrite. It identifies structural problems, duplication, coupling, unclear responsibilities, fragile interfaces, missing tests, and migration risks, then creates a phased plan that preserves behavior.
What it does
The skill reviews code, architecture descriptions, errors, or technical debt notes; identifies high-impact refactoring targets; distinguishes local cleanup from architectural change; defines tests and invariants; proposes safe extraction and migration steps; and produces developer-ready tasks with rollback and review criteria.
What is included
- Current-state diagnosis
- Refactoring goals
- Risk and dependency map
- Target boundaries
- Required test coverage
- Phased migration plan
- Developer task backlog
- Acceptance and rollback criteria
How to use it
1. Download the code-refactoring-planner-SKILL.md file 2. Upload it to your coding assistant 3. Provide the relevant code, architecture, or technical debt description 4. Add constraints such as deadlines, compatibility, and test coverage 5. Implement the plan incrementally and validate behavior after each phase
Examples
Create a safe refactoring plan for a React dashboard where API calls, state management, validation, and UI rendering are mixed inside large components.
A phased plan with code-smell diagnosis, target module boundaries, service and state extraction, validation strategy, test requirements, migration sequence, task breakdown, review checkpoints, and rollback criteria.
