+# AGENTS.md - Yockboard Development Guide
+
+This document provides guidelines for agentic coding agents working on the Yockboard Rails application.
+
+## Project Overview
+
+- **Framework**: Ruby on Rails 8.1.2
+- **Ruby Version**: 3.4.7
+- **Database**: PostgreSQL
+- **Testing**: Minitest (Rails default)
+- **JavaScript**: Turbo + Stimulus with Importmap
+
+## Build / Lint / Test Commands
+
+### Development Server
+```bash
+./bin/dev              # Start development server (alias for bin/rails server)
+bin/rails server -p 3000
+```
+
+### Running Tests
+```bash
+# Run all tests
+bin/rails test
+
+# Run a single test file
+bin/rails test test/models/user_test.rb
+
+# Run a single test by name
+bin/rails test test/models/user_test.rb -n test_user_validity
+
+# Run system tests (browser-based)
+bin/rails test:system
+
+# Run tests in specific directory
+bin/rails test test/controllers/
+```
+
+### Linting & Code Style
+```bash
+# Run RuboCop linter
+bin/rubocop
+
+# Run specific RuboCop check
+bin/rubocop app/models/
+
+# Auto-fix RuboCop issues
+bin/rubocop -a
+```
+
+### Security Scanning
+```bash
+# Scan for Rails security vulnerabilities
+bin/brakeman --no-pager
+
+# Scan for known gem vulnerabilities
+bin/bundler-audit
+
+# Audit JS dependencies
+bin/importmap audit
+```
+
+### Database
+```bash
+bin/rails db:create db:migrate    # Setup database
+bin/rails db:test:prepare         # Prepare test database
+bin/rails db:reset                # Reset database
+```
+
+### CI Pipeline (in .github/workflows/ci.yml)
+- `scan_ruby`: Brakeman + bundler-audit
+- `scan_js`: Importmap audit
+- `lint`: RuboCop
+- `test`: Full test suite with PostgreSQL
+- `system-test`: System/integration tests
+
+## Code Style Guidelines
+
+### General Philosophy
+Follow the **Rails Omakase** style (via `rubocop-rails-omakase`). This is the default Rails team style.
+
+### File Organization
+- Models: `app/models/`
+- Controllers: `app/controllers/`
+- Views: `app/views/controller_name/`
+- Helpers: `app/helpers/`
+- Jobs: `app/jobs/`
+- Mailers: `app/mailers/`
+
+### Naming Conventions
+- **Classes/Modules**: `PascalCase` (e.g., `UserAccount`, `OrderProcessor`)
+- **Database tables**: `snake_case_plurals` (e.g., `user_accounts`, `orders`)
+- **Files**: `snake_case.rb` (e.g., `user_account.rb`, `order_processor.rb`)
+- **Methods/variables**: `snake_case` (e.g., `user_accounts`, `process_order`)
+- **Boolean methods**: End with `?` (e.g., `valid?`, `confirmed?`)
+- **Bang methods**: End with `!` for mutating variants (e.g., `save!`, `update!`)
+- **Query methods**: End with `?` or use plural names (e.g., `admin?`, `users`)
+
+### Routing
+- Use RESTful routes with `resources` when applicable
+- Use namespace for admin/API routes
+- Prefer shallow nesting: `resources :posts, shallow: true do resources :comments end`
+
+### Models
+- Inherit from `ApplicationRecord`
+- Use concerns for shared behavior in `app/models/concerns/`
+- Define associations explicitly
+- Use scopes for common queries
+
+```ruby
+class User < ApplicationRecord
+  has_many :posts, dependent: :destroy
+
+  scope :active, -> { where(active: true) }
+
+  def full_name
+    "#{first_name} #{last_name}".strip
+  end
+end
+```
+
+### Controllers
+- Inherit from `ApplicationController`
+- Use strong parameters for mass assignment
+- Follow RESTful actions pattern
+- Keep controllers thin; push logic to models/services
+
+```ruby
+class UsersController < ApplicationController
+  def index
+    @users = User.active.order(:created_at)
+  end
+
+  def create
+    @user = User.new(user_params)
+    if @user.save
+      redirect_to @user, notice: "User created"
+    else
+      render :new, status: :unprocessable_entity
+    end
+  end
+
+  private
+
+  def user_params
+    params.require(:user).permit(:first_name, :last_name, :email)
+  end
+end
+```
+
+### Views
+- Use ERB with HTML
+- Use Turbo Frames/Streams for SPA-like behavior
+- Prefer Stimulus controllers over vanilla JS
+- Use partials for reusable components
+
+### Testing (Minitest)
+- Test files go in `test/` mirroring `app/` structure
+- Use `test/test_helper.rb` for shared setup
+- Use fixtures in `test/fixtures/` for test data
+
+```ruby
+require "test_helper"
+
+class UserTest < ActiveSupport::TestCase
+  test "valid user" do
+    user = User.new(email: "test@example.com", name: "Test")
+    assert user.valid?
+  end
+
+  test "invalid without email" do
+    user = User.new(name: "Test")
+    assert_not user.valid?
+    assert_includes user.errors[:email], "must be present"
+  end
+end
+```
+
+### Error Handling
+- Use ` rescue` blocks for expected errors
+- Use `fail` or `raise` for unexpected states
+- Flash messages for user feedback
+- Render appropriate HTTP status codes
+
+### Database
+- Use migrations for schema changes: `bin/rails generate migration AddFieldToTable`
+- Use `change` method for reversible migrations
+- Add indexes for foreign keys and frequently queried columns
+
+### Dependencies
+- Add gems to appropriate groups in `Gemfile`
+- Run `bundle install` after adding gems
+- Use `Gemfile.lock` for reproducible builds
+
+### Git Conventions
+- Write clear, concise commit messages
+- Create feature branches for new work
+- Run linter and tests before committing
+
+## Important File Locations
+
+- Routes: `config/routes.rb`
+- Application config: `config/application.rb`
+- Environment configs: `config/environments/`
+- Database config: `config/database.yml`
+- Test config: `test/test_helper.rb`
+
+## Common Tasks
+
+### Generate New Resource
+```bash
+bin/rails generate scaffold ModelName field:type field:type
+bin/rails db:migrate
+```
+
+### Run Specific Gem Command
+```bash
+bundle exec brakeman --no-pager
+bundle exec rubocop
+bundle exec rails test
+```
+
+## Notes
+
+- This project uses **Solid** gems for cache/queue/cable (SolidCache, SolidQueue, SolidCable)
+- Asset pipeline: Propshaft (Rails 8 default)
+- JS: Importmap with Turbo and Stimulus
+- Deployment: Kamal (see `.kamal/`)
