If you can't see what an agent does, you can't improve it, you can't debug it, and you can't trust it.
It's crazy how many teams are building agents with no way to understand what they're doing.
Literally ZERO observability.
This is probably one of the first questions I ask every new team I meet:
Can you show me the traces of a few executions of your agents?
Nada. Zero. Nilch.
Large language models make bad decisions all the time.
Agents fail, and you won't realize it until somebody complains.
At a minimum, every agent you build should produce traces showing the full request flow, latency analysis, and system-level performance metrics.
This alone will surface 80% of operational issues.
But ideally, you can do something much better and capture all of the following:
• Model interactions
• Token usage
• Timing and performance metadata
• Event execution
If you want reliable agents, Observability is not optional.
