How does the Refactoring Assistant help with legacy code?

It recommends specific safety strategies like Characterization Tests and Finding Seams to ensure existing logic is captured and preserved before any structural changes are made.

Can this skill help me decide when to rewrite a system?

Yes, by using the '/refactor decide' command, the skill runs a decision tree that evaluates production status, risk, and maintenance costs to help you choose between refactoring or rewriting.

What is the Boy Scout Rule mentioned in the strategies?

The Boy Scout Rule is a tactical strategy that encourages developers to leave the code slightly cleaner than they found it during routine maintenance or feature development.

Is this Refactoring Assistant language-specific?

No, the skill is language-agnostic. It follows Universal Dev Standards that apply to any programming language or software framework.

How does it verify that refactoring hasn't broken anything?

The workflow includes a structured 'Verify' step that evaluates test coverage and guides you through running safety checks to confirm that the code's external behavior remains unchanged.
