SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Developers lack direct access to live Rails runtime data, making debugging, planning, and verification rely on stale static analysis.

Core Features & Use Cases

  • Execute arbitrary Ruby code inside the running Rails console.
  • Run raw SQL queries against the application database.
  • Retrieve documentation for exact gem versions in use.
  • Stream application logs at various severity levels.
  • List all loaded models and locate source files for classes or methods.

Quick Start

Run /rb:runtime inspect to confirm runtime integration is active and view basic system information.

FAQPage Schema
How do I inspect a running Rails application in real time?▼

Live Rails runtime introspection lets you execute Ruby code, run SQL queries, and view logs directly in the running application. This Skill enables that by integrating Tidewave tooling to query the live runtime instead of relying on static analysis.

Can I run SQL queries against my Rails database from the development console?▼

Yes, you can run raw SQL queries against the application database during development. This allows you to query live data directly for debugging and verification without needing a separate database client.

Do I need the Tidewave gem to execute Ruby code in my Rails runtime?▼

Yes, you need the Tidewave gem installed in your development environment and MCP tools available in your Claude Code session. These dependencies are required to enable live introspection and code execution within the Rails application.

How do I view application logs and list loaded models in a running Rails app?▼

You can stream application logs at various severity levels and list all loaded models using the runtime introspection tools. This provides direct visibility into the application's current state and active components during development.

What are the limitations of live Rails runtime introspection?▼

Live Rails runtime introspection is limited to development environments where the Tidewave gem is installed and MCP tools are available. It is designed for planning, investigation, and implementation phases, not for production environments.
