CowAgent
CowAgent is an open-source, self-hosted "agent harness" that plans tasks, runs tools and skills, and improves itself over time through memory and a growing personal knowledge base, reachable across the web and major chat platforms.
It decomposes a complex task and loops over tools until the goal is reached, and can form a team of agents that each keep their own role, model, skills and knowledge inside one shared conversation. Memory is kept in a three-tier structure, context, daily and core, with automatic distillation and hybrid keyword-plus-vector retrieval, and it auto-curates a Markdown knowledge wiki with a visual, browsable knowledge graph.
A self-evolution process reviews past conversations to improve its own skills, follow up on unfinished tasks, and consolidate memory and knowledge as it is used day to day. It reaches users through Web, WeChat, Feishu, DingTalk, WeCom, QQ, Telegram and Slack, and switches among model providers including Claude, GPT, Gemini, DeepSeek, Qwen, GLM, Kimi, MiniMax and Doubao from its web console.
