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 el-feo/ai-context at ae77f01b54.

    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 rubycritic skill provides static analysis of Ruby code. It identifies potential issues like unused variables, overly long methods, and duplicated code blocks within a given Ruby project or file. This helps improve code quality and maintainability by highlighting areas for refactoring.

When to use it

  • Code Review: Integrate into a CI/CD pipeline to automatically flag potential problems during code reviews.
  • Refactoring: Use to identify sections of code that could benefit from restructuring or simplification.
  • Learning Ruby Best Practices: New developers can leverage the tool's suggestions to learn and adhere to common Ruby coding conventions.
  • Legacy Codebase Improvement: Analyze older, less-maintained Ruby projects to pinpoint areas needing attention.

Key capabilities

  • Static code analysis for Ruby
  • Identification of unused variables
  • Detection of overly long methods
  • Duplicate code detection

Example prompts

  • "Analyze this Ruby file: app/models/user.rb and report any issues."
  • "Run rubycritic on the entire project to find potential refactoring opportunities."
  • "What are the longest methods in my codebase?"

Tips & gotchas

The skill requires a Ruby environment to be set up for proper execution. Ensure that necessary dependencies are installed before using rubycritic.
