Overcoming the Performance Tax in AI Safety: Engineering a Low-Latency Control Plane for Autonomous Agents

1+ hour, 32+ min ago   (668+ words) As enterprise AI systems move from single-turn retrieval-augmented generation (RAG) toward agents that plan, call tools, and modify external state, safety can no longer be treated only as text filtering. The goal is not to promise "zero overhead." The goal…...

1+ hour, 54+ min ago   (606+ words) There is a step at the end of each work session that decides whether each unit of the project is accepted. It gathers, for every unit, whether its test suite passed, whether its checks are current, whether its documentation was…...
