SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Refactoring involves reorganizing code without changing external behavior, but teams often lack a clear, scoped process that ensures safety, test coverage, and maintainability after changes. This skill provides a structured approach to plan, execute, and validate refactors so improvements are predictable and reviewable.

Core Features & Use Cases

  • Invocation modes: Post-Green (REFACTOR step) and explicit user requests.
  • Scoped changes: focus on the minimal set of production and/or test code touched by the refactor.
  • Guardrails: enforce naming conventions, maintain test coverage, and assess risk before applying changes.
  • Companion skills: aligns with code-quality and testing skills to ensure cohesive quality improvements.

Quick Start

Identify a small, well-scoped module and start the refactor workflow, ensuring tests remain green after each change.

FAQPage Schema
How do I safely refactor code after tests pass in a TDD workflow?

To safely refactor code after tests pass, you should enforce scoped changes, adhere to naming conventions, and validate test coverage through a structured assessment, refactor, and commit cycle.

What is the best way to plan a scoped refactor without changing external behavior?

The best way to plan a scoped refactor is to focus on the minimal set of production and test code, assess risks before applying changes, and ensure tests remain green after every modification.

When should I use a structured refactoring process for module maintenance?

You should use a structured refactoring process for module maintenance when you need predictable, reviewable code improvements that enforce naming conventions and maintain test coverage.

Can I refactor architecture and test suites without losing test coverage?

Yes, you can refactor architecture and test suites without losing coverage by enforcing guardrails that assess risk, require naming conventions, and validate tests after each scoped change.

Does this refactoring approach work with red-green-refactor workflows?

Yes, this refactoring approach works directly with red-green-refactor workflows by acting as the post-GREEN phase step to execute safe, scoped code cleanups.

What are the limitations of refactoring without a structured assessment step?

Refactoring without a structured assessment step risks unpredictable changes, broken test coverage, and architecture degradation due to lacking enforced guardrails and naming conventions.
