agrag.eval.trajectory.read_trajectory

read_trajectory(spans:Sequence[ReadableSpan]) -> Trajectory

Read the tool and model steps from finished spans.

Keeps TOOL and LLM spans, drops CHAIN spans, and orders steps by start time rather than export order. Skips spans agrag opens itself and spans nested under an agrag.eval.judge span, so judge calls and BAML request spans never read as agent steps. A step's subagent is the subagent_type of its nearest ancestor task span, or None when no task span encloses it.

Parameters:

• spans (Sequence[ReadableSpan]) – The finished spans of one traced agent run.

Returns:

• Trajectory – The run's trajectory in start order.
