When should I activate the Refactor skill?

Use this skill during the REFACTOR phase of the TDD cycle once your tests are green, or whenever you identify potential code duplication during development.

How does this skill prevent breaking changes?

It enforces a protocol of making small, incremental changes and running the full test suite after every modification to ensure no regressions occur.

What happens if a refactor fails a test?

The skill follows a 'revert immediately' policy, advising you to roll back to the last green state rather than trying to 'fix forward' during a refactor.

Can this skill help with design patterns?

Yes, it provides strategies for extracting interfaces, parameterizing functions, and introducing abstraction layers based on observed code patterns.

Security & Testing

Guides safe code improvements through a search-first workflow and rigorous Test-Driven Development (TDD) principles.

This skill provides a structured framework for the 'Refactor' phase of the Red-Green-Refactor cycle, ensuring code improvements are made safely and logically within Claude Code. It prioritizes a search-first methodology to identify existing patterns before adding new code, helping to eliminate technical debt and redundant logic. By enforcing incremental changes, parameterization strategies, and strict test verification, this skill empowers developers to maintain high-quality codebases without the risk of behavioral regressions.
