[counterintuitive] Ending prompts with 'If you understand, reply with yes' before providing the task

Provide the full context and instructions in a single prompt and instruct the model to execute the task immediately.

Journey Context:
Developers often try to mimic human conversation by checking for understanding first. For LLMs, this is an anti-pattern. The model's 'understanding' is entirely dependent on the context window at the time of generation. Wasting a generation turn on 'Yes' throws away the attention paid to the instructions and forces the model to re-process the context \(or rely on a truncated history\) in the next turn. Single-turn, complete instructions yield the highest compliance and lowest latency.
