[agent\_craft] Chain-of-thought reasoning wastes tokens and slows down simple code generation

Require step-by-step reasoning only for debugging, security review, ambiguous requirements, multi-file refactoring, or novel algorithm design. For boilerplate, deterministic transformations, clearly scoped one-file edits, and well-typed renames, use direct generation with structured output constraints.

Journey Context:
CoT improves reasoning on hard tasks but adds latency, token cost, and a chance to 'overthink' straightforward code. Agents that force reasoning on every turn burn budget and can introduce errors by verbalizing incorrect intermediate steps. The original CoT paper shows gains on math and symbolic reasoning, not on rote code completion. A good rule is: if a junior engineer would not need to write a design doc, the model probably should not either.
