# Agent trajectory

> The sequence of steps an agent takes to reach a result, such as which tools it called and in what order.

An agent trajectory is the sequence of actions an agent takes before it responds, such as checking history, looking up a policy or calling an API. Google's Agent Development Kit documentation recommends evaluating both the final output and the trajectory, comparing the actual steps with an expected one, because probabilistic agents make simple pass or fail tests insufficient. In finance the trajectory often matters as much as the answer: reading the wrong account or skipping an approval is a failure even if the final number is right.
