Create a new Rails project

SKILL.md

2.0 KB, as published. Nobody here has run it

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.
