AGENT.md - Rails Hackatime/Harbor Project

We do development using docker-compose. Run docker-compose ps to see if the dev server is running. If it is, then you can restart the dev server with touch tmp/restart.txt. If not, then bring the dev server up with docker-compose up.

Commands (via Docker Compose)

• Tests: docker compose run web rails test (all), docker compose run web rails test test/models/user_test.rb (single file), docker compose run web rails test test/models/user_test.rb -n test_method_name (single test) - Note: Limited test coverage
• Lint: docker compose run web bundle exec rubocop (check), docker compose run web bundle exec rubocop -A (auto-fix)
• Console: docker compose run web rails c (interactive console)
• Server: docker compose run --service-ports web rails s -b 0.0.0.0 (development server)
• Database: docker compose run web rails db:migrate, docker compose run web rails db:create, docker compose run web rails db:schema:load, docker compose run web rails db:seed
• Security: docker compose run web bundle exec brakeman (security audit)
• JS Security: docker compose run web bin/importmap audit (JS dependency scan)
• Zeitwerk: docker compose run web bin/rails zeitwerk:check (autoloader check)

CI/Testing Requirements

Before marking any task complete, run ALL CI checks locally:

1. docker compose run web bundle exec rubocop (lint check)
2. docker compose run web bundle exec brakeman (security scan)
3. docker compose run web bin/importmap audit (JS security)
4. docker compose run web bin/rails zeitwerk:check (autoloader)
5. docker compose run web rails test (full test suite)

Docker Development

• Interactive shell: docker compose run --service-ports web /bin/bash
• Initial setup: docker compose run web bin/rails db:create db:schema:load db:seed
• Cleanup: Run commands with the --remove-orphans flag to remove unused containers and images

Git Practices

• NEVER commit config/database.yml unless explicitly asked to - contains sensitive local/production database credentials
• NEVER use git add . - always add files individually to avoid accidentally committing unwanted files
• Use git add <specific-file> or git add <directory>/ for targeted commits

Code Style (rubocop-rails-omakase)

• Naming: snake_case files/methods/vars, PascalCase classes, 2-space indent
• Controllers: Inherit ApplicationController, use before_action, strong params with .permit()
• Models: Inherit ApplicationRecord, extensive use of concerns/enums/scopes
• Error Handling: rescue => e + Rails.logger.error, graceful degradation in jobs
• Imports: Use include for concerns, helper_method for view access
• API: Namespace under api/v1/, structured JSON responses with status codes
• Jobs: GoodJob with 4 priority queues, inherit from ApplicationJob, concurrency control for cache jobs
• Auth: ensure_authenticated! for APIs, token via Authorization header or ?api_key=
• CSS: Using Tailwind CSS, no inline styles, use utility classes. We define some custom classes in config/tailwind.config.js and app/assets/tailwind/application.css.
