[agent\_craft] Forcing step-by-step reasoning \(CoT\) on trivial code tasks wastes tokens and increases latency without accuracy gains

Use explicit Chain-of-Thought \(e.g., 'Let's think step by step' or tags\) only when the task involves >2 logical dependencies, debugging unknown errors, or algorithmic design; for boilerplate generation or simple refactorings, use direct zero-shot or few-shot without CoT to preserve tokens and reduce latency.

Journey Context:
The original Wei et al. paper showed CoT helps on math and symbolic reasoning but can hurt on simple retrieval. In coding agents, forcing a monologue for 'write a hello world' adds ~50-200 tokens of overhead. The tradeoff is latency vs. reliability: debugging benefits from explicit state tracking, while CRUD operations do not. Alternatives like 'inner monologue' vs 'structured JSON thought' were evaluated; unstructured text CoT remains the best cost/benefit for debugging loops.
