[counterintuitive] Using streaming API responses makes the overall agent loop execute faster

Use streaming only for UI/UX responsiveness. For backend agent loops \(e.g., tool calling chains\), non-streaming or waiting for the full response is often more efficient for parsing and prevents premature tool execution.

Journey Context:
Developers enable streaming thinking it speeds up the agent. While it reduces Time-To-First-Token, it complicates parsing. An agent often needs the complete JSON tool call to validate and execute it. Parsing streamed chunks into a valid JSON object requires complex buffering and can lead to race conditions or premature execution if the agent tries to act on an incomplete tool call. Stream for the user, batch for the agent logic.
