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 dchuk/rails_ai_agents at e3f5bd8229.

    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 provides a reusable module of code in Ruby on Rails applications, known as a "Concern." Concerns allow you to encapsulate common functionality and easily include it into multiple models without duplicating code. This promotes cleaner, more maintainable Rails projects by sharing logic across different model classes.

When to use it

  • Sharing behavior: When several models need the same methods or validations.
  • Avoiding duplication: To prevent repeating similar code blocks in multiple model files.
  • Organizing complex models: To break down large, monolithic models into smaller, more manageable pieces.
  • Adding common functionality: When you want to add a set of features (like scopes or callbacks) to several different models.

Key capabilities

  • Provides reusable code modules (Concerns).
  • Encapsulates common functionality for Rails models.
  • Promotes cleaner and more maintainable codebase.
  • Allows easy inclusion of shared logic into multiple models.

Example prompts

  • "Create a Concern called Auditable that adds timestamps for creation and updates."
  • "Include the SoftDeletes Concern in the Article model."
  • "Generate a Concern to handle common validation rules for user profiles."

Tips & gotchas

  • Requires a working Ruby on Rails application.
  • Understanding of Rails models and inheritance is helpful.
