Interview question · Agent, Tool & MCP Security

How do rate limits, budgets and loop limits reduce abuse of an AI agent, and how do you set them?

Bound work where it is dispatched, account for concurrent branches and retries, and keep uncertain operations reserved. Choose limits from workload evidence and operational capacity, then preserve useful progress when a bound is reached.

What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

Alder’s task has a cap of 100 exercise units, 40 committed and 30 reserved. Two workers each request another 20 units.

  1. Can both workers be admitted under the same remaining balance?
  2. What if the admitted worker times out before reporting usage?
  3. Should resuming the task restore its original 100-unit budget?
  4. What should the implementation demonstrate?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
