tkoenig Rails Pattern Research
What This Is
The Real World Rails repository is a collection of 200+ production Rails
application source code, included as git submodules. 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
~/Development/tkoenig/playground/real-world-rails. If not found, ask the
user where it lives.
Filtering to Active Projects
Only research apps that have been actively maintained — exclude any project without a commit in the last year. Before searching, run the helper script to get the list of active apps:
bash <skill-dir>/scripts/active-apps.sh /path/to/real-world-rails
Limit all searches to the directories output by that script. Ignore stale or abandoned projects — their patterns may be outdated or reflect deprecated Rails conventions.
What To Do
The user gives you a topic. Spin up parallel agents to search the active 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.
