Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned mhattingpete/claude-skills-marketplace at b5b34bcf4c.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill automatically improves existing Python code for readability, efficiency, and maintainability using proven refactoring patterns. It systematically refactors code across multiple files, intelligently switching between native tools (Grep and Edit) and a code-execution mode to optimize token usage. For 10 or more files, the skill leverages the code-execution skill to achieve significant token savings compared to traditional methods.

When to use it

This skill is helpful in these scenarios:

  • Renaming identifiers (variables, functions) within a codebase.
  • Replacing specific patterns of code with alternatives.
  • Updating calls to functions or APIs.
  • Converting deprecated coding patterns to newer ones.
  • Performing large-scale refactoring tasks across many files.

Key capabilities

  • Systematic Refactoring: Applies changes consistently across multiple files.
  • Mode Switching: Automatically selects between native tools and code execution for efficiency (10+ files).
  • Grep Integration: Uses Grep to find occurrences of patterns within files, with options for displaying context lines and line numbers.
  • Edit Integration: Utilizes Edit with the replace_all=true flag to replace all instances of a pattern in a file.
  • Token Optimization: Significantly reduces token usage when refactoring large codebases (up to 90% savings).

Example prompts

Here are some example prompts you can use:

  • "rename oldName to newName"
  • "replace all getUserData with fetchUserData"
  • "convert var count = 0 to let count = 0"

Tips & gotchas

  • Planning is Key: The skill recommends finding all instances of a pattern first, reviewing their context, and considering edge cases (strings, comments) before making changes.
  • Test After Refactoring: It's highly recommended to run tests after refactoring to ensure the code still functions correctly.
  • Case Sensitivity: Be explicit about case sensitivity when defining Grep patterns.
