Safe Refactor

Overview

Refactoring is restructuring code without changing its observable behavior. This skill enforces a small-step, test-verified workflow that minimises risk, keeps every commit behaviour-preserving, and integrates with existing code-review and testing skills.

When to Use

Use this skill when:

• You need to restructure, rename, or reorganise code — not add features.
• A legacy module needs cleaning up before new work can begin.
• You're extracting a function, class, or file and must not break callers.
• Any change where "does it still work?" must have a reproducible answer.
