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 yennanliu/cs_basics at 19c64f7eb7.

    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

The code-refactor-master skill enables AI agents to analyze existing codebases and generate optimized, refactored versions. It focuses on improving readability, reducing complexity, and enforcing best practices without altering core functionality.

When to use it

  • Modernizing legacy code written in outdated styles or frameworks.
  • Reducing technical debt by simplifying complex logic blocks.
  • Standardizing formatting and naming conventions across a project.
  • Preparing code for team onboarding by enhancing clarity.

Key capabilities

  • Analyzes current code structure to identify inefficiencies.
  • Generates refactored code that maintains original behavior.
  • Applies industry-standard best practices for maintainability.
  • Optimizes variable names and function definitions for clarity.

Example prompts

  • "Refactor this Python script to use modern type hinting and remove unused imports."
  • "Analyze the provided JavaScript module and suggest structural improvements for scalability."
  • "Rewrite this legacy SQL query set to follow current performance best practices."

Tips & gotchas

Ensure you provide complete context or full files when requesting refactors, as partial snippets may lead to incomplete optimization. Always review generated code before merging, as the skill prioritizes style and structure over deep logic verification.
