What works, what goes wrong, and how to tell the difference.
Give it the profile rather than the guess. An agent reading real timings finds the actual cost; an agent guessing optimises the wrong loop confidently.
The rule that matters more than the tool: give the agent something that can prove it succeeded. A task with a test, a build or a linter attached comes back verified. A task with none comes back plausible, and plausible is the expensive kind of wrong.
