Workflow Steps

1

Identify Refactoring Opportunities

Find code that would benefit most from refactoring.

Analyze this code for refactoring opportunities: [paste code]. Look for: code smells, duplication, overly complex functions, poor naming, and SOLID principle violations. Prioritize by: impact × ease × risk.
ClaudeBest with Claude

Why Claude: Claude identifies code smells and prioritizes effectively.

2

Plan the Refactoring

Create a safe, incremental refactoring plan.

Create a refactoring plan for [describe what you want to improve]. Break into small, independently deployable steps. Each step should: be testable, not break existing functionality, and move toward the goal.
ClaudeBest with Claude

Why Claude: Claude creates safe, incremental refactoring plans.

3

Add Safety Net

Ensure tests exist before making changes.

Before refactoring this code: [paste code], what tests should exist? Generate test cases that verify current behavior. These will ensure the refactoring doesn't break anything.
ClaudeBest with Claude

Why Claude: Claude identifies critical paths that need test coverage.

4

Execute Refactoring

Make the changes following the plan.

Refactor this code: [paste code]. Goal: [what to improve]. Show: before and after for each change, explain why each change improves the code. Preserve exact functionality.
ClaudeBest with Claude

Why Claude: Claude shows clear before/after with explanations.

5

Verify Behavior

Ensure the refactored code works correctly.

Review this refactored code: [paste before and after]. Verify: functionality is preserved, no subtle behavior changes, edge cases still handled, and no new bugs introduced. Flag any concerns.
ClaudeBest with Claude

Why Claude: Claude catches subtle behavioral changes in refactoring.

6

Document Changes

Record what was changed and why.

Document this refactoring for the PR: [describe changes]. Write: what was changed, why (what problem it solved), any API changes, and migration notes if applicable.
ClaudeBest with Claude

Why Claude: Claude writes clear technical documentation.
