A smart agent checks its work and knows when to say 'done!' instead of going forever.
5 min · Reviewed 2026
The big idea
How does an agent know when it's finished? Smart designers give it 'done criteria': 'Stop when you have 5 facts.' 'Stop when the email is sent.' Without these, agents might wander forever.
Some examples
'Stop when you have 3 good ideas.'
'Stop when the homework is checked.'
'Stop when the task is on the calendar.'
'Stop when you've answered all 5 questions.'
Try it!
Pick a chore (clean a desk). Define 'done': 'When the desk has nothing on it.' Stop EXACTLY when that's true.
Practice this safely
Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about completion, not to let it make the decision for you.
Ask AI to explain completion in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "How Good Agents Know When the Job Is Truly Done" and ask for two possible next steps plus one reason each step might be wrong.
Check done-criteria against a trusted source, teacher, adult, expert, or original document before you use it.
