## Implemented Features

### Chat API (`implemented/chat-api.md`)
The core Chat API that enables AI-powered conversations within GNS3 projects.

**Key Features:**
- Server-Sent Events (SSE) for streaming responses
- Project-level session isolation
- Session management (CRUD operations)
- Statistics tracking (messages, tokens, LLM calls)
- User-level LLM configuration

**Status:** ✅ Implemented

### LLM Model Configs (`implemented/llm-model-configs.md`)
Multi-level LLM model configuration system.

**Key Features:**
- System-wide defaults
- Group-level configurations
- User-level overrides
- Runtime parameter adjustment
- Model provider abstraction

**Status:** ✅ Implemented

### Command Security (`implemented/command-security.md`)
Security framework for AI-generated commands.

**Key Features:**
- Command filtering and validation
- Dangerous operation detection
- HITL (Human-in-the-Loop) confirmations
- Audit logging

**Status:** ✅ Implemented

### Context Window Management (`implemented/context-window-management.md`)
Optimization strategies for handling large project contexts.

**Key Features:**
- Intelligent content filtering
- Token usage optimization
- Summary generation
- Context compression

**Status:** ✅ Implemented

### Node Control Tools (`implemented/node-control-tools.md`)
Tools for controlling network device lifecycle in GNS3 projects.

**Key Features:**
- Start nodes with progress tracking
- Quick start for automated workflows
- Stop nodes for lab shutdown
- Batch operations support
- Mode-based access control

**Status:** ✅ Implemented

### Multi-Vendor Device Support (`implemented/multi-vendor-device-support.md`)
Multi-vendor network device support with custom Netmiko drivers for Huawei, Ruijie, and VPCS devices.

**Key Features:**
- Custom HuaweiTelnetCE driver for Huawei CloudEngine (no authentication)
- Custom RuijieTelnetEnhanced driver for Ruijie OS (interactive command handling)
- Custom VPCSTelnet driver for VPCS simulator (no authentication, ANSI code stripping)
- Cisco IOS Telnet support
- Dynamic device type detection from GNS3 tags
- Unified Nornir + Netmiko architecture
- Vendor-specific command handling (VRP system-view, Ruijie interactive prompts, VPCS simple prompts)

**Tested Vendors:**
- Cisco IOS (Telnet)
- Huawei CloudEngine (Telnet, custom driver)
- Ruijie (锐捷) OS (Telnet, custom enhanced driver)
- VPCS (Virtual PC Simulator, Telnet, custom driver)

**Status:** ✅ Implemented

## Future Enhancements

The following features are currently under consideration or development:

- Configuration Templates: Template-based configuration generation for multi-vendor network devices
- Vision-based Topology Creation: Create network topologies from images/diagrams
- Enhanced HITL Workflows: Advanced Human-in-the-Loop confirmation patterns
- Web UI Enhancements: Improved management interfaces

## Contributing

When adding new documentation:

1. **Implementation:** Add documentation to `implemented/` when feature is complete
2. **Naming:** Use concise names like `{feature}.md`
