Ruby

Use this skill first for every Ruby ecosystem task. It is a router, not a Ruby language tutorial. Load only the references needed for the current task.

Operating Boundaries

Complete the smallest set of actions that fully satisfies the request. Repository instructions and existing project conventions override generic advice in this skill.

Unless the task requires and authorizes it, do not:

• install or update gems, runtimes, or other dependencies;
• rewrite unrelated configuration, CI, or development tooling;
• fetch remotes, open browsers, or generate standalone reports; or
• replace a project wrapper with a host command that bypasses its environment.

A reference describes how to work; it does not grant additional authority.
