Rails & bundler

Prerequisites

• Ruby 3.2+ installed
• An existing Rails project (or create one with rails new myapp)
• Claudette installed and running

Configuration

Create a .claudette.json in your project root:

{
  "scripts": {
    "setup": "bundle install && bin/rails db:setup"
  },
  "instructions": "This is a Rails 8 project. Use Ruby 3.3+. Run tests with bin/rails test."
}

This setup script will:

1. Install gem dependencies
2. Create the database, load the schema, and run seeds

Add to Claudette

1. Open Claudette and click + Add Repo
2. Select your Rails project directory
3. Create a new workspace — gems install and the database sets up automatically

Example Prompts

“Add a RESTful API for managing products with JSON serialization using jbuilder”

“Create a Stimulus controller for a sortable table with drag-and-drop”

“Set up Action Cable for real-time notifications”

Tips

• If you use rbenv or asdf, make sure the correct Ruby version is configured in .ruby-version
• For API-only apps, mention that in your instructions so the agent doesn’t generate views
