Refactor Code Workflow

This skill ensures you refactor code safely by verifying behavior before and after changes.

Workflow Steps

1. Pre-Check (Safety Net)

• Verify Current State: Run existing tests for the target module. They must pass before you touch anything.
• Backup: If no tests exist, strongly consider creating a "Snapshot Test" or backup file first.

2. Strategy

• Identify Goal: What are you improving? (Readability, DRY, Performance, Security).
• Plan: Decide which classes/methods will be extracted, renamed, or simplified.

3. Execution (Refactoring)

• Apply Changes: Perform the refactoring steps (Extract Method, Rename Variable, Introduce Value Object, etc.).
• Keep Logic: Do NOT change the business logic or external behavior.

4. Verification

• Run Tests: Run the tests again. They MUST still pass.
• Lint: Ensure the new code follows project style guidelines.
