Report #16945

[research] Agent achieves the right goal using the wrong tools, masking severe orchestration bugs

Evaluate the agent's trajectory by scoring tool-selection accuracy independently from task completion. Use a strict exact match or forbidden tool eval on the trace's span events.

Journey Context:
If an agent is asked to read a file and instead runs a shell command to cat the file, the final answer is correct, but the trajectory is wrong and potentially dangerous. Final-outcome evals give this a passing grade. By analyzing the OpenTelemetry trace and evaluating the specific tool spans invoked, you can fail runs that use forbidden tools or deviate from required orchestration paths, catching privilege escalation or inefficiency early.
