724 Office Ai Agent

This is a surprisingly complete production agent system in 3,500 lines of pure Python with almost no framework bloat. You get 26 built-in tools, three-layer memory (session, compressed facts, vector retrieval), MCP protocol support, and cron scheduling out of the box. The runtime tool creation is clever: the agent can write and hot-load new Python functions mid-conversation without restarting. It's built for WeChat Work but the HTTP webhook design makes it adaptable. The three markdown files (SOUL.md, AGENT.md, USER.md) for personality and procedures are a nice touch for teams who want repeatable agent behavior. If you need a self-contained agent that actually runs 24/7 without pulling in LangChain or similar, this is worth studying.
