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 an AI agent to understand and utilize Ruby blocks, procs, and lambdas. It allows for passing code snippets as arguments to methods, creating closures, and defining anonymous functions within the Ruby language. The skill facilitates more complex logic and data manipulation through functional programming techniques.

When to use it

  • Data Transformation: When needing to apply a custom calculation or filtering rule to a collection of data in a Ruby environment.
  • Event Handling: To define short, inline actions triggered by specific events within a Ruby application.
  • DSL Creation: For building domain-specific languages where code blocks represent commands or configurations.
  • Method Arguments: When needing to pass small chunks of executable Ruby code as arguments to other methods for dynamic behavior.

Key capabilities

  • Understanding of Ruby blocks
  • Proc creation and usage
  • Lambda definition and application
  • Passing code snippets as method arguments
  • Closure support

Example prompts

  • "Write a Ruby block that squares each number in this array: [1, 2, 3, 4]."
  • "Create a proc to greet a user by name."
  • "Pass a lambda function to the map method to convert strings to uppercase."

Tips & gotchas

  • Requires a Ruby runtime environment for execution.
  • The agent's understanding is limited to the syntax and common use cases of blocks, procs, and lambdas within Ruby.
