Core concepts

A trace is built from four primitives. Learn these and you can read any run.

Plan

Before acting, the agent decomposes the request into typed steps with a cost estimate. The plan is inspectable, you can see what it intends to do before it does it.

Step

A single unit of work. Each step is timestamped and carries its own token and dollar cost.

Tool call

When a step needs the outside world, it calls a permissioned tool. The arguments and the result are logged verbatim, never paraphrased.

Verification

The final gate. Claims are grounded against retrieved sources; a run that fails verification retries within budget or escalates to a human.
