How to give an AI agent a task it can finish

Practical rules for writing agent tasks: be specific, give limits, say when to stop. With before-and-after examples.

Say the outcome, not the clicks

Good: “Find a direct flight from Berlin to Lisbon on May 12 under $200, leaving before noon.” Less good: “Go to a flight site and search.” The agent plans the clicks; you describe what “done” looks like.

Give it the details it can’t guess

Model numbers, dates, budgets, city, number of people, your preferences. If the task needs personal details for a form, paste them into the task once — it’s faster than answering questions one by one.

Set limits

  • Budget: “under $60”.
  • Scope: “check three stores”, “first two pages of results”.
  • Quality bar: “rated 4.5+”, “posted this week”.

Limits keep the task short and the result comparable.

Tell it what to return

“A table with name, price and link”, “three options with one downside each”, “a filled form, don’t submit”. A clear output format turns a long run into something you can use in seconds.

Before and after

Before: “Find me a hotel in Porto.”
After: “Find hotels in Porto old town for 2 adults, 12–15 May, under $150 a night, rated 8.5+, free cancellation. Give me 4 options with price, area and one honest downside.”

Start on the right page

If you already have the store, site or form open, start the task there. The agent works in the tab you’re using and saves the search step.

Next: Is it safe to let an AI click for you?
