A nightly job blocks its web request thread while waiting on a long Claude call, and the service times out under load. What engineering practice addresses this?

Answer: A — Asynchronous processing — don't block a request thread on a long-running call

This is plain software engineering tested in an LLM context — a long-running call belongs on an async path or a queue, not blocking a synchronous request thread. No model or prompt change fixes a blocking architecture.
