[counterintuitive] Appending 'Let's think step by step' to force chain-of-thought reasoning

Use explicit structural delimiters for reasoning \(e.g., or \) or rely on native reasoning models \(o1/o3\) that handle CoT internally.

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3 era models to unlock emergent reasoning. For modern models, it's a weak, uncontrolled nudge that often results in rambling, unfocused reasoning. Structured reasoning tags allow the agent to separate planning from execution, or use dedicated reasoning models that don't need the prompt hack at all.
