How would you keep an AI agent from performing an unsafe tool action?

Interview Question

What the interviewer is testing

Security boundaries
Tool authorization
Safe failure

Real-World Sample Answer

I would approach “How would you keep an AI agent from performing an unsafe tool action?” by clarifying the requirements first, then using these considerations: in a real interview, i would not jump straight to a technology choice. for “how would you keep an ai agent from performing an unsafe tool action?”, i would first separate model reasoning from tool permissions. then i would apply least privilege to every tool and validate arguments and policy before execution. i would also use step, cost, and time limits. finally, i would add observability and human approval for sensitive actions. i would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.. I would state my assumptions and defend the trade-offs rather than presenting the choice as universally correct.

What a Strong Answer Should Cover

In a real interview, I would not jump straight to a technology choice. For “How would you keep an AI agent from performing an unsafe tool action?”, I would first separate model reasoning from tool permissions. Then I would apply least privilege to every tool and validate arguments and policy before execution. I would also use step, cost, and time limits. Finally, I would add observability and human approval for sensitive actions. I would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.

Common Mistakes

Trusting the model to self-police
Giving broad tool permissions
No action-level audit trail

Interviewer Follow-ups

What assumptions would you clarify before committing to the design?
What changes if the scale, reliability target, security requirement, or budget changes?
What is the biggest failure mode in your proposed approach?
