UFO (UI-Focused agent) and Galaxy constitute a multi-agent AI framework for automating GUI-based tasks across Windows, Linux, and mobile platforms. The system uses LLM-driven agents (AppAgent, HostAgent, ConstellationAgent) that interact with desktop applications via UI automation (UIA, COM) and execute distributed task workflows modeled as DAGs (task constellations). It includes a client-server architecture with WebSocket-based Agent Interaction Protocol (AIP), MCP tool servers, a configurable RAG knowledge substrate, and a Web UI (React+FastAPI) for real-time monitoring and control. The framework is primarily an application with strong research elements: it supports trajectory analysis, evaluation agents, demonstration learning, and configurable LLM backends (OpenAI, Claude, Gemini, DeepSeek, Ollama).
