# Documentation Guidelines

This document outlines documentation standards and processes for the Robota project.

## Documentation Standards

### Code Documentation

- Include JSDoc comments for all public APIs
- Add inline comments for complex algorithms or business logic
- **Smart Example Generation**: Create examples when they add value to understanding
- **All code comments must be written in English**: JSDoc comments, inline comments, etc.
- **All log messages and error messages must be written in English**: Logger messages, error messages, console output, etc.

### Example Code Guidelines

- **Value-driven Examples**: Create examples when they significantly improve API understanding
- **Real-world Scenarios**: Use realistic use cases rather than trivial examples
- **Complete and Executable**: Examples should be complete and immediately runnable
- **Progressive Complexity**: Start with basic examples, then show advanced usage
- **Error Handling**: Include error handling in examples when relevant

### API Documentation Standards

- Document all parameters with types and constraints
- Include return type documentation
- Specify when methods throw exceptions
- Document side effects and state changes
- **Version Compatibility**: Document breaking changes and migration paths

## External Documentation Process

- Update relevant documentation for new features
- Reflect API changes in documentation immediately
- Update CHANGELOG.md for all user-facing changes
- **Documentation-driven Development**: Write documentation before implementation for major features

## Accessibility and Developer Experience

- **Clear Error Messages**: Provide actionable error messages with suggestions
- **Progressive Enhancement**: Core functionality should work without optional features
- **Debug Support**: Include debug modes and detailed logging options
- **IDE Integration**: Provide excellent TypeScript support for autocomplete

## Plugin Architecture Documentation

- Core functionality extended through plugin system
- Plugins implement lifecycle hooks for cross-cutting concerns
- Plugin registration and management through unified interface
- **Plugin Isolation**: Plugins should not directly depend on each other

## Performance and Security Documentation

### Performance Considerations

- **Async-first Design**: Use async/await for all I/O operations
- **Memory Management**: Implement proper cleanup for resources
- **Batching**: Batch similar operations when possible
- **Caching**: Cache expensive computations with appropriate invalidation
- **Streaming**: Support streaming for large data operations

### Security Considerations

- **Input Validation**: Validate and sanitize all external input
- **API Key Protection**: Never log or expose API keys in error messages
- **Dependency Security**: Regularly audit and update dependencies
- **Error Information**: Limit sensitive information in error messages

## Testing Strategy Documentation

- **Unit Tests**: Test individual components in isolation
- **Integration Tests**: Test component interactions
- **End-to-end Tests**: Test complete user workflows
- **Error Path Testing**: Test error conditions and edge cases
