Wanted to introduce our latest research on agentic systems called Signals. If you&#x27;ve been building agents, you&#x27;ve probably noticed that there are far too many agent traces/trajectories to review one by one, and using humans or extra LLM calls to inspect all of them gets expensive really fast. The paper proposes a lightweight way to compute structured “signals” from live agent interactions so you can surface the trajectories most worth looking at, without changing the agent’s online behavior. Computing Signals…</p><p>3 points; 0 discussion replies on HN. <a href="https://hackerpaper.kaipfister.de/p/2604.00356/">Paper and source history</a>. A submission is not an endorsement.</p>cs.AI
