## Definition

Agents that build their own tools — autonomous agents capable of extending their own capabilities by generating tools for tasks they can't yet handle, evolving from BabyAGI's simple 100-line LLM loop into a broader agent ecosystem [^8c9661cb-02b8-5d3d-ab7f-367a64893914@58] [^8c9661cb-02b8-5d3d-ab7f-367a64893914@128] [^8c9661cb-02b8-5d3d-ab7f-367a64893914@236] [^8c9661cb-02b8-5d3d-ab7f-367a64893914@247].

In this channel's material, **self-building agents** is the term Yohei Nakajima — VC at Untapped Capital and creator of BabyAGI — uses for agents that build their own tools rather than only running the ones humans hand them [^8c9661cb-02b8-5d3d-ab7f-367a64893914@58]. It appears in the context of how autonomous agents evolve: BabyAGI started as a simple 100-line LLM loop, and the agent ecosystem that grew around it pushed toward agents capable of extending themselves by generating tools for tasks they can't yet handle [^8c9661cb-02b8-5d3d-ab7f-367a64893914@128]. The material is explicit that this is more than a slogan — the conversation explores what “agents that build their own tools” actually looks like in practice, beyond the simple loop that made BabyAGI viral [^8c9661cb-02b8-5d3d-ab7f-367a64893914@236] [^8c9661cb-02b8-5d3d-ab7f-367a64893914@247]. So as you read the channel's synthesis on Building AI Products and Startups, treat self-building agents as a concrete stage in agent evolution — agents that autonomously create tools to expand their own capabilities — not as a vague stand-in for any autonomous agent.
