Your question is Agent Core Capabilities. 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).

You need to log in / sign up to chat or submit.

Problem

What core capabilities does your agent have? Walk through the end-to-end tool-calling flow: tool registration, parsing, invocation, and returning results.

Asked in the round 1 stage. Explain the design as a practical end-to-end system, including how an agent discovers tools, selects and validates a tool call, executes it safely, and incorporates the result into the next model step. Discuss interfaces, errors, observability, and safeguards.
