Agent Metrics
Domain: Agent Architecture
Motivation
Agent metrics measure how a run actually went: token usage, duration, and per-record detail. The trajectory record inspector surfaces these numbers per step so you can see where time and tokens went, and message feedback adds the human quality signal on top.
Concrete Example
The Trajectory tab’s record inspector shows token usage, duration, input, and output for each turn and step of an agent run.
Analogy
A timesheet plus a fuel gauge for the worker’s shift.
