Rails Pattern Research

What This Is

The Real World Rails repository is a collection of 200+ production Rails application source code. The apps/ directory contains the full source of each app — models, migrations, schema, controllers, views, concerns, gems. The engines/ directory contains Rails engines.

Locating the Repository

Look for a directory called real-world-rails with an apps/ subdirectory. Check the current working directory first, then ~/src/real-world-rails. If not found, ask the user where it lives.

What To Do

The user gives you a topic. Spin up parallel agents to search the apps for how real codebases implement that pattern. Read actual code — models, schemas, migrations, associations, validations, query patterns — not just file names. Synthesize what you find into a clear analysis.

If the user's wording suggests they want help choosing a pattern for their current project (words like "compare for us", "which fits best", "adversarial", "debate", "evaluate for our project"), also spin up adversarial agents that each argue for a different pattern in the context of the current project's architecture and goals.
