I built an AI agent for production incidents. The interesting part is when it refuses to act.

I wrote this for the All Things Agentic Hackathon. Every incident-response demo you have seen ends the same way: something breaks, the agent fixes it, everyone applauds. I want to show you the opposite. Here is my agent, at 95% confidence, having correctly diagnosed a bad deployment, deciding not to roll it back. That refusal is the whole project. The question underneath At 3am an alert fires. An engineer wakes up, reads several hundred log lines, correlates them against recent deploys, and rolls something back. Most of it is mechanical. It is an obvious target for automation. But "automate it with an LLM" does not dissolve the problem, it relocates it. The new question is: how much would you let an agent change in production without asking you first? Give it too little and it is a chatbot that writes summaries. Give it too much and one confidently wrong diagnosis takes down your service at 3am with nobody watching. I named the project Sonjomon — Bengali for restraint. The autonomy ladder An agent should not have one blanket permission level. How far it may act alone is a function of two things: how confident it is, and how much damage the proposed action does if that confidence turns out to be wrong. tier = f(confidence, blast_radius) OBSERVE record findings, take no action SUGGEST recommend to a human, do not execute APPROVE stage the action, execute on explicit approval ACT execute now, then verify independently A restart is medium risk — reversible in seconds. A rollback is high risk — it shifts production traffic, and a needless rollback during a real outage extends it. Deleting data is critical, and no confidence level unlocks it. Six conditions can only ever push the tier down, never up: the blast-radius ceiling, thin evidence, a similar action that just failed, a third attempt at the same fix, a stale incident, and a global dry-run switch. Nothing pushes it up. A wrong action is far more expensive than a missed one. Three things the model does not control It
