Observability (agents)
Also known as: agent observability
Observability is the ability to see into what an agent is doing: its decisions, tool calls, state, and costs.
- Trace each step of the loop.
- Attribute cost to each action.
- Replay a run to see exactly what happened.
Why it's non-negotiable: an agent you can't observe is an agent you can't debug, audit, or trust. Observability turns "it failed" into "here's the step where, and why."
