description: Plan implementation of a Rails feature with multi-tenant architecture and DaisyUI
allowed-tools: Bash, Read, Glob, Grep
---
You are planning a new feature for a Rails application with multi-tenant architecture.
ARCHITECTURE CONTEXT:
- This project uses TWO databases:
* Primary database: Non-tenanted, for global/shared data
* Account database: Tenant-based, for customer-specific data
- Always verify which database a model should use before planning
- Models in the account database must be properly scoped to the current tenant
ARCHITECTURE PATTERNS:
- **NO SERVICE OBJECTS** - Do not use or suggest service object pattern
- Use rich domain models with business logic
- Extract shared behavior into Concerns (app/models/concerns)
- Use PORO (Plain Old Ruby Objects) when models don't need persistence
- Keep controllers thin - delegate to models and concerns
TEST-DRIVEN DEVELOPMENT (TDD):
- **MANDATORY**: All implementation must follow TDD approach
- Write unit tests BEFORE implementation:
* Model tests: validations, associations, scopes, instance methods, class methods
* Controller tests: request specs for each action
- Plan should include test specifications for:
* Each model with expected behavior
* Each controller action with success/failure cases
* Edge cases and error handling
- Use RSpec or Minitest based on project conventions
STYLING & COMPONENTS:
- **CRITICAL**: Use DaisyUI components throughout the implementation
- Keep all styles aligned with existing DaisyUI patterns
- Before planning, CHECK DOCUMENTATION:
* Use context7 for DaisyUI component reference
* Use context7 for Rails documentation
* Use tidwave MCPs for additional technical documentation
- Prefer DaisyUI's semantic component classes over custom Tailwind
PLANNING PROCESS:
1. First, analyze the current project structure:
- Examine relevant controllers, models, and views
- Check existing patterns for similar features
- Review the database schema (both primary and account)
- **Identify DaisyUI components already in use**
- Review existing Stimulus controllers and patterns
- Check existing concerns and model patterns
- Identify testing framework (RSpec/Minitest)
2. Consult documentation BEFORE asking questions:
- Check context7 for DaisyUI components relevant to the feature
- Check context7 for Rails best practices
- Check tidwave MCPs for technical references
3. Ask up to 10 clarifying questions in groups of 2-3:
- Database & Models: Which database? Associations? Validations? Business logic?
- UI/UX: Which DaisyUI components? User interactions? View structure?
- Integration: Where does this fit? Lazy loading? Turbo frames?
- Technical: Stimulus controllers? Background jobs? Permissions?
- Testing: Edge cases? Authorization scenarios?
- Wait for answers between question groups
4. Provide a comprehensive implementation plan including:
- **TDD Test Plan**: Specify tests to write for each model and controller
- Database choice justification (primary vs account)
- Model structure with correct database configuration
- Business logic placement (models, concerns, POROs)
- Controller actions and routing (thin controllers)
- **DaisyUI component specifications for each UI element**
- View structure (Turbo frames, Stimulus controllers)
- Styling approach using DaisyUI (matching existing patterns)
- Testing strategy with specific test cases
- Migration steps
- Integration points with existing code
IMPLEMENTATION ORDER:
1. Write failing tests (Red)
2. Implement minimal code to pass tests (Green)
3. Refactor (extract concerns, improve design)
4. Repeat for each feature increment
RAILS SPECIFICS TO CONSIDER:
- Hotwire/Turbo for dynamic updates
- Stimulus controllers for JavaScript behavior
- Proper tenant scoping for account database models
- DRY principles and Rails conventions
- Database connection configuration for multi-tenancy
- ActiveModel for POROs when needed
