Real World Rails

What it does

The Real World Rails skill provides access to a repository of over 200 production Rails applications, including their full source code (models, migrations, controllers, views, etc.) and Rails engines. It enables an AI agent to search this codebase for specific implementation patterns within real-world Rails projects. The agent can then synthesize findings into clear analyses or facilitate comparisons between different approaches when choosing a pattern for a new project.

When to use it

• When you need examples of how specific Rails patterns are implemented in production code.
• To compare different architectural patterns and determine which best suits your current project's goals.
• When seeking guidance on implementing features like validations, associations, or query patterns within a Rails application.
• To understand how real-world Rails projects structure their models, migrations, and schemas.

Key capabilities

• Search a repository of 200+ production Rails applications.
• Analyze code (models, schema, migrations, etc.) rather than just file names.
• Synthesize findings into clear analyses.
• Generate adversarial agents to debate the merits of different patterns for specific projects.

Example prompts

• "Show me how real-world Rails apps implement optimistic locking."
• "Compare and contrast different approaches to implementing user authentication in these applications."
• "Which pattern is best for handling file uploads, considering a project with REST API endpoints?"

Tips & gotchas

• The skill requires access to the real-world-rails repository, which should contain an apps/ subdirectory. The agent will prompt you for its location if it cannot be found in the current working directory or ~/src/real-world-rails.
• When asking about pattern selection, use wording that suggests a comparison ("compare for us," "which fits best") to trigger the adversarial agent functionality.
• The skill focuses on code analysis and pattern identification; it does not provide general Rails development assistance beyond what can be gleaned from the repository's examples.
