What This Skill Does

The Ruby skill for OpenClaw provides an expert-level advisory layer for Ruby development. It is specifically designed to help developers navigate the nuances of the Ruby language, including object mutability, scoping quirks, and metaprogramming hazards. Whether you are debugging complex ActiveRecord queries, refactoring legacy code for performance, or ensuring that your Ruby methods adhere to idiomatic standards, the Ruby skill provides architectural oversight to prevent common runtime failures.

Installation

To integrate this skill into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/ruby

Use Cases

• Refactoring: Converting imperative code into clean, idiomatic Ruby using blocks, procs, and lambdas correctly.
• Performance Tuning: Identifying potential N+1 query patterns in Rails applications and optimizing hash/array mutation patterns.
• Security Hardening: Auditing the use of eval, send, and method_missing to ensure that dynamic code execution is contained and secure.
• Bug Prevention: Debugging subtle object identity issues where equal? and == are conflated, or troubleshooting shared state in default hash arguments.

Example Prompts

1. "I am getting unexpected behavior when appending to a string in a loop. Can you explain the mutable string trap and how I can use frozen string literals to fix this?"
2. "Refactor this class to replace method_missing with a more robust implementation that correctly overrides respond_to_missing?."
3. "Help me identify why my Rails application is suffering from N+1 query issues in this controller action and suggest an ActiveRecord eager loading solution."

Tips & Limitations

When using this skill, always provide the specific Ruby version you are targeting, as behavior for features like block shadowing changed significantly after Ruby 3.0. Note that this skill is advisory; it provides code analysis and suggestions based on established best practices. While it excels at identifying logic errors related to language internals, it cannot replace comprehensive test suites. Always ensure you have a suite of RSpec or Minitest files to verify the agent's suggestions. Be mindful that metaprogramming is powerful but can make static analysis difficult, so document your dynamic code patterns thoroughly.
