[agent\_craft] Chain-of-Thought \(CoT\) prompting causing overthinking, incorrect logic paths, or 'hallucinated bugs' in simple code generation tasks

Disable CoT \(remove 'think step by step' or 'let's work through this'\) for straightforward boilerplate, CRUD operations, or syntax translation. Enable CoT only when the task explicitly requires multi-step reasoning: complex algorithm design, debugging unknown failures, or optimizing performance with trade-off analysis.

Journey Context:
The 'Let's Verify Step by Step' paper showed CoT helps math/reasoning, but code generation is different. For simple tasks \(e.g., 'write a Python function to read a JSON file'\), CoT makes the model generate an explanation about error handling, then implement overly complex try-except blocks that weren't requested, or worse, introduce subtle bugs in the 'reasoning' that propagate to the code. Common error is applying CoT universally after seeing it work for debugging tasks. The boundary: if the task is 'generate' \(creation\) and the spec is clear, CoT hurts. If the task is 'debug' or 'design algorithm with constraints', CoT helps.
