Refactoring

Checked
cosmix·vlatest·backend·MIT

Automates complex backend code refactoring tasks, improving performance, readability, and maintainability based on best practices.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

Installs under a different name. Its SKILL.md names it loom-refactoring, not the name it is listed under, so the command below uses that name.
  1. 1

    Run this in your project

    terminal
    $ npx skills add cosmix/loom --skill loom-refactoring -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 cosmix/claude-loom at e6f00616cc.

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

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill, cosmix-refactoring, helps improve existing code by restructuring it without changing its external behavior. It can identify and eliminate redundancies, simplify complex logic, and enhance the overall readability of codebases. The agent leverages this skill to produce cleaner, more maintainable software.

When to use it

  • Legacy Codebase Cleanup: Refactor a large, monolithic codebase to improve modularity and reduce technical debt.
  • Performance Optimization: Identify inefficient algorithms or data structures within existing code and suggest improvements.
  • Code Modernization: Update older codebases to utilize more modern programming paradigms and language features.
  • Preparing for New Features: Refactor a section of code before adding new functionality, making the process easier and less error-prone.

Key capabilities

  • Code Restructuring
  • Redundancy Elimination
  • Simplification of Complex Logic
  • Readability Enhancement

Example prompts

  • "Refactor this Python function to improve its readability." (followed by code)
  • "Can you identify and eliminate any redundant code in this JavaScript file?" (followed by code)
  • “Modernize this Java class using current best practices.” (followed by code)

Tips & gotchas

The skill requires the agent to have a solid understanding of the programming language being refactored. Providing clear context about the purpose and functionality of the code will improve the quality of the refactoring suggestions.
