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 personamanagmentlayer/pcl at 79ccaa9820.

    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

Ruby Expert Skill Guide

What it does

This skill equips AI agents with specialized knowledge of the Ruby programming language, enabling them to write, debug, and refactor code effectively. It allows agents to understand Ruby syntax, standard libraries, and best practices for building robust applications.

When to use it

  • Generating idiomatic Ruby scripts for backend logic or automation tasks.
  • Debugging runtime errors or syntax issues within existing Ruby projects.
  • Refactoring legacy codebases to improve performance and maintainability.
  • Explaining complex Ruby concepts like blocks, procs, and metaprogramming.

Key capabilities

  • Syntax Mastery: Accurately generates valid Ruby code adhering to language conventions.
  • Error Resolution: Identifies and suggests fixes for common runtime exceptions and logic bugs.
  • Code Optimization: Refactors inefficient patterns into cleaner, more performant Ruby solutions.
  • Library Integration: Assists in utilizing the Ruby standard library and popular gems effectively.

Example prompts

  • "Write a Ruby script that scrapes data from a local JSON file and outputs it as CSV."
  • "Debug this Rails controller error: undefined method 'user' for nil:NilClass."
  • "Refactor this block-heavy function to use modern Ruby syntax with explicit blocks."

Tips & gotchas

Ensure the AI agent has access to the specific version of Ruby or gems your project requires, as behavior can vary between versions. While the skill handles general logic well, complex architectural decisions may still require human oversight for domain-specific business rules.
