Browser Automation Guidelines

When working with Rails applications that have Tidewave running:

Use Tidewave for:

  • Running Ruby code (project_eval)
  • Database queries (executesqlquery)
  • Checking logs (get_logs)
  • Finding source locations (getsourcelocation)
  • Getting documentation (get_docs)

Use Chrome DevTools for:

  • Taking screenshots
  • Performance profiling
  • Console error checking
  • Network request analysis
  • Visual UI testing
  • Core Web Vitals analysis

Do NOT use Chrome DevTools for tasks that Tidewave can accomplish directly.

Prerequisites

  1. Ruby 3.3+ installed via rbenv, rvm, or asdf
  2. Rails 8.1+: gem install rails
  3. PostgreSQL installed and running
  4. Claude Code with this plugin installed

Post-Setup Workflow

  1. Start the Rails server:

``bash cd my_app && bin/rails server ``

  1. Open Claude Code in another terminal:

``bash cd my_app && claude ``

  1. Start building with natural language:

- "What models does this app have?" - "Show me the routes" - "Create a User model with email and name"

Notes

  • Tidewave MCP only works when the Rails server is running on port 3000
  • Hotwire Club MCP works independently with its built-in SQLite database
  • Chrome DevTools is provided by the plugin (not project-level)
  • The setup auto-configures permissions for fast development (no prompts)
