[counterintuitive] 'If you understand, output Understood' or conversational filler

Start immediately with the task. Use tool calls or structured output to confirm state, not conversational acknowledgments.

Journey Context:
Early chatbot interactions trained developers to check if the model 'understood' the prompt. This wastes tokens, increases latency, and provides a false sense of security—a model can output 'Understood' and still fail the task. In an agentic loop, state is maintained by the system; the agent should just act and return the result or use a tool.
