Messaging Telegram | Discord | Slack | WhatsApp | Matrix | WebChat
LLM Providers Anthropic | OpenAI | Gemini | Ollama
Security AES-256-GCM encryption | Ed25519 skill signing | sandboxed tools
Protocols HTTP | WebSocket | gRPC | MCP client | A2A server
Key design decisions:
- Sandboxed tool execution - process-level and container-level isolation for shell, file, HTTP, and browser tools
- Persistent memory - structured key-value store with immutable key protection and content-addressed hashing
- Human-in-the-loop - configurable approval modes per tool (auto / ask / deny)
- Smart context windowing - hash-based change detection to avoid redundant token usage
