refactor-code

refactor-code is a skill for Claude Code, Cursor from emaraschio/cursor-commands. It costs 11 tokens per session (366 once invoked), scanned A, original, MIT.

A code-cleanup workflow that makes existing code easier to read and maintain while keeping its behavior the same. It can also look for duplicated code, complex logic, and avoidable performance costs.

In plain words
What is it for?
Use it to reorganize functions or components, simplify algorithms, improve names, reduce duplication, and document important logic without changing what the program does.
Why use it?
It reduces the difficulty of understanding and changing code without requiring a feature rewrite. It helps reveal unclear names, repeated logic, deep nesting, and weak error handling.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

refactor-code scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Overview

Refactor the selected code to improve its quality while maintaining the same functionality, providing the refactored code with explanations of the improvements made.

Steps

  1. Code Quality Improvements
    • Extract reusable functions or components
    • Eliminate code duplication
    • Improve variable and function naming
    • Simplify complex logic and reduce nesting
  2. Performance Optimizations
    • Identify and fix performance bottlenecks
    • Optimize algorithms and data structures
    • Reduce unnecessary computations
    • Improve memory usage
  3. Maintainability
    • Make the code more readable and self-documenting
    • Add appropriate comments where needed
    • Follow SOLID principles and design patterns
    • Improve error handling and edge case coverage

Refactor Code Checklist

  • Extracted reusable functions or components
  • Eliminated code duplication
  • Improved variable and function naming
  • Simplified complex logic and reduced nesting
  • Identified and fixed performance bottlenecks
  • Optimized algorithms and data structures
  • Made code more readable and self-documenting
  • Followed SOLID principles and design patterns
  • Improved error handling and edge case coverage

Guardrails

  • Preserve existing behavior; a refactor must not change observable output.
  • Keep changes within the refactor target; do not touch unrelated code.
  • Do not commit, push, merge, or run production scripts without consent; wait for an explicit request before any destructive git action.
  • Do not print, log, or commit secrets or credentials encountered while refactoring; flag any exposed secret instead.
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
