    One round-trip from the harness to the model provider. The harness sends the current context; the provider returns one response (a tool call or a final answer). A single user message can spawn many model provider requests if the agent calls tools — each tool result triggers another request.

    Usage:

    "One question burned forty thousand tokens?"

    "Look at the tool calls — twelve grep, eight read, four edits. Each tool result spawns another model provider request, and the whole session prefix re-sends every time."
