Definition
Every question in a request is evaluated in parallel against the same state, and the answer to one question never becomes context for another. The parallel-questions cookbook batches a 13-question regulatory briefing into one call and reports 12.2x lower cost and 10x lower latency with no change in answers.
Coding agents fall into the one-question-per-call habit more than people do, which is why TypeSafe's agent skill explicitly tells agents to put many questions in each call.

Ask everything the system might need in one request, then let code throw away what it does not use. The ticket-triage example sends a category plus four speculative questions in parallel.
