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 elliotjlt/claude-skill-potions at 8858a8fe86.

    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

The safe-refactor skill allows you to safely refactor code, minimizing risk and ensuring functionality is preserved. It can identify potential issues during refactoring, suggest safer alternatives, and automatically apply changes while maintaining test coverage. This helps improve code quality without introducing regressions or breaking existing features.

When to use it

  • Modernizing legacy code: Refactor older codebases to utilize newer language features or libraries.
  • Improving readability: Clean up complex functions or classes for better maintainability.
  • Preparing for new features: Restructure code before adding significant functionality.
  • Automating repetitive tasks: Streamline common refactoring patterns, such as renaming variables or extracting methods.

Key capabilities

  • Safe code transformations
  • Test coverage preservation
  • Issue identification during refactor
  • Suggestion of safer alternatives

Example prompts

  • "Refactor this function to use a more modern approach." (Provide the function's code)
  • "Rename all instances of 'oldVariable' to 'newVariable' in this file."
  • "Extract this block of code into a separate method and ensure tests still pass."

Tips & gotchas

The skill requires access to the codebase being refactored. It is recommended to start with small, isolated changes to validate its behavior before applying it to larger sections of code.
