Your question is Tool Calling With Structured JSON. 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 are to evaluate tool calling across a scenario with the order of the tools defined and structured JSON payload.
Implement a practical pipeline that executes predefined tools in order, validates each JSON request and response, and prevents later tools from running when an earlier step fails. Demonstrate schema validation, idempotent retries, structured error reporting, and tests for valid, invalid, and out-of-order calls.
