Most AI agent demos stop at the final answer.

Mine did too at first. I had a support agent that could answer a refund question, call a policy tool, and avoid a prompt-injection path. From the outside, it looked fine.

Then I asked a less comfortable question: if this agent broke in production, would I actually know what happened?

That question became TraceGate.

TraceGate is a release gate for AI agents built with OpenTelemetry and SigNoz. It runs agent scenarios, sends telemetry to SigNoz, then checks whether the run produced enough evidence to safely ship.
