refactor

refactor is a command for Claude Code from swesmith/davila7__claude-code-templates.734b8a50. It costs 0 tokens per session (335 once invoked), scanned A, a copy of refactor, MIT.

A code-improvement assistant for JavaScript and TypeScript that changes internal structure while preserving intended behavior.

In plain words
What is it for?
Use it to extract reusable functions or components, improve types, convert callbacks to Promises or async/await, optimize code, and verify changes with tests.
Why use it?
It helps remove duplicate code, simplify difficult logic, improve names and error handling, and replace outdated patterns without changing what the code does.

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 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 6d 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.

Origin

This is a copy

100% identical to refactor — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Code Refactoring Assistant

Refactor $ARGUMENTS following modern JavaScript/TypeScript best practices.

Task

I'll help you refactor code by:

  1. Analyzing the current implementation
  2. Identifying improvement opportunities
  3. Applying modern patterns and practices
  4. Maintaining existing functionality
  5. Ensuring type safety and test coverage
  6. Documenting the changes made

Process

I'll follow these steps:

  1. Examine the code to understand its purpose and structure
  2. Identify code smells, anti-patterns, or outdated approaches
  3. Plan the refactoring strategy with clear goals
  4. Implement changes incrementally while maintaining behavior
  5. Verify refactored code with tests
  6. Document improvements and benefits

Refactoring Techniques

I can apply various refactoring techniques:

  • Converting to modern JavaScript/TypeScript features
  • Improving type definitions and type safety
  • Extracting reusable functions and components
  • Applying design patterns appropriately
  • Converting callbacks to Promises or async/await
  • Simplifying complex conditionals and loops
  • Removing duplicate code
  • Improving naming and readability
  • Optimizing performance
  • Enhancing error handling

Modern Practices I Can Apply

  • ES modules and import/export syntax
  • Optional chaining and nullish coalescing
  • Array and object destructuring
  • Spread and rest operators
  • Template literals
  • Arrow functions
  • Class fields and private methods
  • TypeScript utility types
  • Functional programming patterns
  • React hooks (for React components)

I'll ensure the refactored code maintains compatibility with your project's requirements while improving quality and maintainability.

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.

refactor is a command published in the GitHub repository swesmith/davila7__claude-code-templates.734b8a50 (2 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 335 tokens. A static security scan graded it A with 0 findings. It is 100% identical to refactor, differing in 0 lines, and is treated as a copy.
