SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It cleans up freshly-changed code by reducing duplication, removing smells, and refactoring for readability and maintainability without changing behavior.

Core Features & Use Cases

  • Diff-driven refactoring: reviews the git diff (by default, changed files vs the merge-base) to target what actually changed.
  • DRY and code-smell detection: flags duplication, magic numbers, poor naming, tight coupling, oversized units, and inefficient patterns.
  • Safety-net for behavioral changes: runs a test-first gate when structural refactors could alter behavior, and defaults to mechanical-only changes when no test net is available.

Quick Start

Ask your agent to simplify a small set of recently modified files by routing the request with the phrase "simplify".

FAQPage Schema
How do I refactor freshly changed code without changing its behavior?▼

To refactor freshly changed code safely, review the git diff to target only what actually changed, gate structural refactors behind a test net, and apply mechanical-only changes when no tests are available.

What is the best way to detect code smells and DRY violations in a focused git diff?▼

Detecting code smells and DRY violations in a focused git diff involves scanning changed files versus the merge-base to flag duplication, poor naming, tight coupling, and inefficient patterns within that specific scope.

Can I clean up code automatically after addressing PR comments or fixing bugs?▼

Yes, you can clean up code after addressing PR comments or fixing bugs by performing smell reviews over the git diff and supporting safe auto-application of mechanical improvements within the changed scope.

Do I need a test safety net to apply structural refactoring to my codebase?▼

A test safety net is required to gate structural refactors that could alter behavior, but when no test net is available, the process defaults to mechanical-only changes to ensure safety.

What types of code improvements can I apply to recently modified files?▼

You can apply code improvements to recently modified files by reducing duplication, removing smells, refactoring for readability, and ensuring less coupling to produce a smaller and drier version.
