[agent\_craft] Enforcing step-by-step reasoning on every code generation task increases token costs 3x without improving correctness on boilerplate code

Use explicit Chain-of-Thought \(CoT\) only for novel algorithmic problems, complex debugging, or multi-step refactoring; use direct generation \(zero-shot\) for CRUD operations, standard patterns, and boilerplate with strong type signatures in the prompt.

Journey Context:
The common wisdom that 'more reasoning is better' leads agents to force CoT on every task, but this introduces hallucination paths for simple code—models overthink and add unnecessary complexity. CoT provides value when the search space is large \(debugging requires hypothesis testing\) or when the algorithm is non-obvious \(dynamic programming\), but for boilerplate, it merely consumes tokens that could be used for larger context windows. The tradeoff is latency versus accuracy: direct generation is O\(1\) reasoning, CoT is O\(n\) tokens. The pattern is to branch on task classification: use a cheap classifier \(or regex on the prompt\) to route 'hard' tasks to CoT and 'easy' tasks to direct generation.
