Generate a new Rails project named $1 in the current directory. You may reference @CLAUDE.md for general guidance, though the guidance here takes precedence.

Tech Stack

Set up the following tech stack:

• Rails ~8 with PostgreSQL - Server-side framework and database
• Inertia.js ~2.3 - Bridges Rails and React for SPA-like experience without API
• React ~19.2 - Frontend UI framework
• Vite ~5 - JavaScript bundler with HMR
• Tailwind CSS ~4 - Utility-first CSS framework
• Sidekiq 8 - Background job processing with scheduled jobs via sidekiq-scheduler
• Redis - Sessions, caching, and job queue

Rails guidance

• Do not use Kamal or Docker
• Do not use Rails "solid_*" components/systems
• Development should generally match production settings where possible
• Use Redis for caching

Database

• All tables use UUID primary keys (pgcrypto extension)
• Timestamps use timestamptz for timezone awareness
• JSONB columns for flexible metadata storage
• Comprehensive indexing strategy for performance
• Encrypted fields for sensitive data (OAuth tokens, API keys)

Background jobs

• Use Sidekiq 8 with Redis

Testing

• Always use minitest
• Use mocha gem and VCR for external services (only in the providers layer)
• Prefer OpenStruct for mock instances
• Only mock what's necessary

Code maintenace

• Run bundle exec rubocop -a after significant code changes
• Use .rubocop.yml for style configuration
• Security scanning with bundle exec brakeman

Frontend

• All React components and views should be TSX

General guidance

• Ask lots of clarifying questions when planning. The more the better. Make extensive use of AskUserQuestionTool to gather requirements and specifications. You can't ask too many questions.

Verify

Verify the boilerplate is working by running bin/rails server and accessing the application at http://localhost:3000 via playwright MCP.
