## Components

### CLI Framework
- **Click Integration**: Command-line interface using Click framework
- **Rich UI**: Enhanced terminal output with Rich library
- **Command Structure**: Organized command groups and subcommands
- **Help System**: Built-in help and documentation

### Core Commands
- **Connection Commands**: Connect, disconnect, health check
- **Topology Commands**: List, create, delete queues and exchanges
- **Message Commands**: Publish, subscribe, acknowledge messages
- **Status Commands**: Show connection status and basic metrics

### User Experience
- **Interactive Mode**: Real-time interaction with RabbitMQ
- **Command History**: Persistent command history
- **Error Messages**: User-friendly error messages
- **Progress Indicators**: Visual feedback for long operations

### Language Support
- **English**: Primary language support for MVP
- **Localization Ready**: Framework for future multi-language support (20 languages in full product)
- **Constitution Requirement**: Full product MUST support 20 most spoken languages

## Technical Requirements

### Command Structure
```

## Dependencies
- click for CLI framework
- rich for enhanced terminal output
- asyncio for concurrent operations
- MCP client for server communication

## Implementation Notes
- Use Click for command-line interface
- Implement Rich for enhanced terminal output
- **Semantic Discovery Support**: CLI must support `search-ids` → `get-id` → `call-id` workflow
- **Direct Commands**: Provide convenient shortcuts for common operations
- Support both interactive and batch modes
- Provide comprehensive help and examples
- Handle MCP client communication errors gracefully
- **Structured Logging**: Log all CLI operations using structlog
- **uvx Support**: README.md must include examples showing `uvx` usage
- **Accessibility**: Support screen readers and keyboard-only navigation (constitution requirement)
