Vincent Weisser(@vincentweisser):Excited to release Prime-Agent A self-improving RLM harness for coding and long-running autonomous tasks. Our goal is to enable everyone to build and use self-improving agents; and the harnesses, models, and infrastructure to support them. Prime-Agent is token-efficient and expressive through programmatic tool calling, context as a variable, multi-agent messaging, and a self-improving harness state. It combines three ideas we’ve been exploring: >Recursive Language Model–native programmatic tool calling >Persistent multi-agent orchestration >A self-improving continual harness Together, they let the model act on, and improve its own context and harness. @kevinjosethomas @a1zhang @sethkarten and team cooked 🙌 Install it: curl -fsSL https://t.co/2qdEweqEkX
