 # Project Structure
 ## Directory Organization
 ```
 [Define your project's directory structure. Examples below - adapt to your project type]
 Example for a library/package:
 project-root/
 ├── src/                    # Source code
 ├── tests/                  # Test files  
 ├── docs/                   # Documentation
 ├── examples/               # Usage examples
 └── [build/dist/out]        # Build output
 Example for an application:
 project-root/
 ├── [src/app/lib]           # Main source code
 ├── [assets/resources]      # Static resources
 ├── [config/settings]       # Configuration
 ├── [scripts/tools]         # Build/utility scripts
 └── [tests/spec]            # Test files
 Common patterns:
 - Group by feature/module
 - Group by layer (UI, business logic, data)
 - Group by type (models, controllers, views)
 - Flat structure for simple projects
 ```
 ## Naming Conventions
 ### Files
 - **Components/Modules**: [e.g., `PascalCase`, `snake_case`, `kebab-case`]
 - **Services/Handlers**: [e.g., `UserService`, `user_service`, `user-service`]
 - **Utilities/Helpers**: [e.g., `dateUtils`, `date_utils`, `date-utils`]
 - **Tests**: [e.g., `[filename]_test`, `[filename].test`, `[filename]Test`]
 ### Code
 - **Classes/Types**: [e.g., `PascalCase`, `CamelCase`, `snake_case`]
 - **Functions/Methods**: [e.g., `camelCase`, `snake_case`, `PascalCase`]
 - **Constants**: [e.g., `UPPER_SNAKE_CASE`, `SCREAMING_CASE`, `PascalCase`]
 - **Variables**: [e.g., `camelCase`, `snake_case`, `lowercase`]
 ## Import Patterns
 ### Import Order
 1. External dependencies
 2. Internal modules
 3. Relative imports
 4. Style imports
 ### Module/Package Organization
 ```
 [Describe your project's import/include patterns]
 Examples:
 - Absolute imports from project root
 - Relative imports within modules
 - Package/namespace organization
 - Dependency management approach
 ```
 ## Code Structure Patterns
 [Define common patterns for organizing code within files. Below are examples - choose what applies to your project]
 ### Module/Class Organization
 ```
 Example patterns:
 1. Imports/includes/dependencies
 2. Constants and configuration
 3. Type/interface definitions
 4. Main implementation
 5. Helper/utility functions
 6. Exports/public API
 ```
 ### Function/Method Organization
 ```
 Example patterns:
 - Input validation first
 - Core logic in the middle
 - Error handling throughout
 - Clear return points
 ```
 ### File Organization Principles
 ```
 Choose what works for your project:
 - One class/module per file
 - Related functionality grouped together
 - Public API at the top/bottom
 - Implementation details hidden
 ```
 ## Code Organization Principles
 1. **Single Responsibility**: Each file should have one clear purpose
 2. **Modularity**: Code should be organized into reusable modules
 3. **Testability**: Structure code to be easily testable
 4. **Consistency**: Follow patterns established in the codebase
 ## Module Boundaries
 [Define how different parts of your project interact and maintain separation of concerns]
 Examples of boundary patterns:
 - **Core vs Plugins**: Core functionality vs extensible plugins
 - **Public API vs Internal**: What's exposed vs implementation details  
 - **Platform-specific vs Cross-platform**: OS-specific code isolation
 - **Stable vs Experimental**: Production code vs experimental features
 - **Dependencies direction**: Which modules can depend on which
 ## Code Size Guidelines
 [Define your project's guidelines for file and function sizes]
 Suggested guidelines:
 - **File size**: [Define maximum lines per file]
 - **Function/Method size**: [Define maximum lines per function]
 - **Class/Module complexity**: [Define complexity limits]
 - **Nesting depth**: [Maximum nesting levels]
 ## Dashboard/Monitoring Structure (if applicable)
 [How dashboard or monitoring components are organized]
 ### Example Structure:
 ```
 src/
 └── dashboard/          # Self-contained dashboard subsystem
    ├── server/        # Backend server components
    ├── client/        # Frontend assets
    ├── shared/        # Shared types/utilities
    └── public/        # Static assets
 ```
 ### Separation of Concerns
 - Dashboard isolated from core business logic
 - Own CLI entry point for independent operation
 - Minimal dependencies on main application
 - Can be disabled without affecting core functionality
 ## Documentation Standards
 - All public APIs must have documentation
 - Complex logic should include inline comments
 - README files for major modules
 - Follow language-specific documentation conventions

 # User Templates
 This directory allows you to create custom templates that override the default Spec Workflow templates.
 ## How to Use Custom Templates
 1. **Create your custom template file** in this directory with the exact same name as the default template you want to override:
   - `requirements-template.md` - Override requirements document template
   - `design-template.md` - Override design document template
   - `tasks-template.md` - Override tasks document template
   - `product-template.md` - Override product steering template
   - `tech-template.md` - Override tech steering template
   - `structure-template.md` - Override structure steering template
 2. **Template Loading Priority**:
   - The system first checks this `user-templates/` directory
   - If a matching template is found here, it will be used
   - Otherwise, the default template from `templates/` will be used
 ## Example Custom Template
 To create a custom requirements template:
 1. Create a file named `requirements-template.md` in this directory
 2. Add your custom structure, for example:
 ```markdown
 # Requirements Document
 ## Executive Summary
 [Your custom section]
 ## Business Requirements
 [Your custom structure]
 ## Technical Requirements
 [Your custom fields]
 ## Custom Sections
 [Add any sections specific to your workflow]
 ```
 ## Template Variables
 Templates can include placeholders that will be replaced when documents are created:
 - `{{projectName}}` - The name of your project
 - `{{featureName}}` - The name of the feature being specified
 - `{{date}}` - The current date
 - `{{author}}` - The document author
 ## Best Practices
 1. **Start from defaults**: Copy a default template from `../templates/` as a starting point
 2. **Keep structure consistent**: Maintain similar section headers for tool compatibility
 3. **Document changes**: Add comments explaining why sections were added/modified
 4. **Version control**: Track your custom templates in version control
 5. **Test thoroughly**: Ensure custom templates work with the spec workflow tools
 ## Notes
 - Custom templates are project-specific and not included in the package distribution
 - The `templates/` directory contains the default templates which are updated with each version
 - Your custom templates in this directory are preserved during updates
 - If a custom template has errors, the system will fall back to the default template
