To simplify code changes without breaking behavior, this Skill diffs your current branch against its base, applies targeted improvements for clarity and reuse, and runs your test suite to verify no regressions occurred.

You can automatically review code quality and efficiency by spawning three parallel reviewer agents that assess reuse, quality, and efficiency improvements on your modified branch scope.

The best way to ensure simplifications preserve functionality is running the project's test suite after applying changes, requiring both typecheck, lint, and tests to pass before completing the process.

The simplification process works with both approaches, operating by diffing the current branch against its base to focus on the modified scope, or by targeting an explicitly named file.

You need to simplify code after feature branch changes to improve clarity, reuse, and maintainability, reducing technical debt while ensuring the modified logic remains easy to understand and scale.

A limitation of using automated agents to refactor code is the strict dependency on passing typecheck, lint, and test suites after applying changes, meaning incomplete test coverage may block valid simplifications.
