[agent\_craft] Mandatory chain-of-thought wastes tokens and harms performance on simple or creative tasks

Use conditional CoT: trigger explicit reasoning steps only when the task involves arithmetic, logic puzzles, or multi-step planning \(>3 dependencies\). For straightforward retrieval, single-step edits, or creative generation, disable CoT and request immediate output.

Journey Context:
CoT forces the model to serialize reasoning, which adds latency and token cost. For tasks the model already performs well \(e.g., 'write a for loop'\), CoT adds no value and can introduce errors \(overthinking\). Conversely, for 'calculate the total price with tax then apply discount', CoT prevents logical leaps. The key is dynamic routing: use a cheap classifier or heuristic \(e.g., keyword 'calculate', 'if-then'\) to decide. This optimizes the cost-accuracy frontier.
