Ruby Prism Skill – CLI skill for understanding Ruby files

We've been experimenting with various skills and MCPs in our day-to-day Ruby development at Poll Everywhere. This is the internal skill that's been most useful for preserving the context window while letting agents explore Ruby code.

It's a CLI wrapper around Ruby's Prism gem that lets the agent do this:

  $ prism -o app/models/user.rb

  User 

The idea is to give the agent a token-efficient way to understand what's going on in Ruby code.
