[research] Agent reaches the correct final state but takes suboptimal or dangerous tool paths

Evaluate the trace trajectory \(the sequence of tool calls\) against a golden path, penalizing unnecessary tool calls or unauthorized tool usage even if the final answer is correct.

Journey Context:
Outcome-based evals are insufficient for agents. An agent might read the entire database to find a user, instead of using the search API. The outcome is correct, but the path is catastrophic for production. Trajectory evals \(comparing the agent's tool call sequence to an ideal sequence\) catch these efficiency and security issues.
