Your question is Handle Failed Agent Tool Calls. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

Scenario

You're building an LLM agent that answers user requests by calling tools such as search, database lookup, and ticket creation. In practice, some tool calls fail, return partial results, or time out, and the model may still try to continue as if the tool succeeded.

Question

How do you handle tool calls that fail or time out mid-execution?

What This Tests

  • Agent orchestration around tool failures
  • Prompting for graceful degradation and refusal
  • Evaluation of unsupported claims after failures
  • Prompt injection awareness in tool outputs
