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 jeffallan/claude-skills at 1be15d8064.

    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 rails-expert skill provides deep knowledge of Ruby on Rails, including best practices for building scalable web applications, database modeling, and API development. It can assist with writing clean code, debugging common issues, and optimizing performance in a Rails environment.

When to use it

  • You're developing a new feature in a Ruby on Rails application and need guidance on implementation.
  • You're encountering an error or bug in your Rails app and need help diagnosing the issue.
  • You want to optimize your Rails app for speed, security, or maintainability.
  • You're designing a database schema and need advice on Rails-specific conventions.

Key capabilities

  • Writing and refactoring Ruby on Rails code
  • Debugging common Rails errors and exceptions
  • Optimizing performance with caching, query optimization, and background jobs
  • Setting up RESTful APIs with Rails
  • Understanding Rails conventions and best practices

Example prompts

  • "How do I implement nested resources in my Rails app?"
  • "Why am I getting a 'No route matches' error when submitting this form?"
  • "Can you help me optimize this slow ActiveRecord query?"

Tips & gotchas

  • Ensure your Rails version is compatible with the advice provided.
  • While the skill can assist with general guidance, it may not replace hands-on debugging or testing in a real environment.
