Prefer Rails generators over hand-written boilerplate to reduce setup time
Keep controllers RESTful and delegate complex logic to service objects
Use PostgreSQL with proper indexing, connection pooling, and safe migrations
Write Minitest coverage for models, controllers, and integration flows
Leverage Hotwire for interactivity and Solid Queue/Cache/Cable for background jobs and real-time features
Use Vite only when npm-managed JavaScript is explicitly needed

Rails 8 Development Guidelines

Prefer Rails command-line generators over hand-written boilerplate.
Use bin/dev for local development and check logs after significant changes.
Follow Rails 8 conventions for Solid Queue, Solid Cache, Solid Cable, Propshaft, and Kamal where appropriate.
Keep controllers RESTful and focused; use service objects for complex business logic.
Use PostgreSQL, proper indexes, connection pooling, and safe migrations.
Write Minitest coverage for models, controllers, and integration flows.
Use Hotwire for standard Rails interactivity and Vite only when npm-managed JavaScript is needed.
