[counterintuitive] Using 'Let's think step by step' as a magic bullet for complex coding tasks

Replace generic Chain-of-Thought phrases with domain-specific reasoning frameworks or enforced tool use \(e.g., 'First write test cases, then implement, then run tests'\).

Journey Context:
'Let's think step by step' was a breakthrough in 2022 for zero-shot reasoning, but modern models over-rely on it, producing verbose, unfocused natural language reasoning that degrades accuracy on code tasks. Code requires deterministic execution, not just linguistic reasoning. Forcing the model to use a Python REPL or write tests first shifts reasoning from unreliable internal monologue to verifiable external state.
