Lesson 7 of 8
Evaluate an Agent
Evaluate an agent on task success, tool use, stopping behavior and safety—not just final text quality.
Active reading
Understand the idea
Record the goal, actions taken, tool results, number of steps, final state and whether human approval was triggered correctly.
Example
Run 20 test tasks including unavailable tools, ambiguous goals and cases that should stop for human review.
Practice
Apply this lesson to one real task you already have, then write down how you would verify the result.
Common mistake
Rewarding an agent for finishing quickly even when it takes unsafe shortcuts.
Key takeaway
An agent is reliable only when its path to the result is also acceptable.
