[counterintuitive] Does adding 'Let's think step by step' improve coding reasoning?

Replace zero-shot CoT triggers with structured reasoning tags \(e.g., , \) or use models with native hidden reasoning tokens.

Journey Context:
The 'Let's think step by step' phrase was a breakthrough for GPT-3 \(Kojima et al., 2022\) because it unlocked emergent reasoning. Modern models are post-trained on CoT data; simply uttering the phrase often results in shallow, generic reasoning or wasted output tokens. Worse, it mixes reasoning with final output, increasing hallucination risk. Structured tags force the model to separate planning from execution, or native reasoning models \(like o1\) handle it architecturally.
