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 thebushidocollective/han at 19caa51d5f.

    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 enables AI agents to leverage Ruby's metaprogramming capabilities. It allows for dynamic method definition, class modification at runtime, and generation of code within code, leading to more flexible and expressive solutions. The agent can use this skill to automate repetitive coding tasks or create highly adaptable systems.

When to use it

  • Automated Code Generation: Generate boilerplate code based on a data schema or configuration file.
  • Dynamic DSL Creation: Build custom domain-specific languages (DSLs) tailored to specific problem domains.
  • Runtime Class Modification: Add or modify methods and attributes of classes dynamically, adapting behavior without restarting the application.
  • Automated Testing: Generate test cases based on method signatures and expected behaviors.

Key capabilities

  • Dynamic Method Definition
  • Class Modification at Runtime
  • Code Generation within Code (Eval)
  • method_missing Handling
  • define_method Usage

Example prompts

  • "Generate a Ruby class called 'ReportGenerator' with methods for creating PDF and CSV reports."
  • "Add a method to the existing 'User' class that automatically logs user activity to a database."
  • “Write code to dynamically create a method named calculate_total on the Order class.”

Tips & gotchas

This skill requires a solid understanding of Ruby programming fundamentals. Overuse of metaprogramming can make code harder to debug and maintain, so use it judiciously for complex tasks where its benefits outweigh the potential drawbacks.
