[agent\_craft] Chain-of-Thought reasoning increases hallucinations in code generation but helps debugging

Suppress CoT \(direct output\) for generation tasks; explicitly request step-by-step reasoning only when analyzing existing code or debugging errors

Journey Context:
CoT forces the model to commit to intermediate abstractions that may be incorrect, poisoning the final code generation with hallucinated API methods invented during reasoning. For debugging, the explicit reasoning acts as a trace to identify assumption mismatches. Research shows CoT helps logical reasoning \(GSM8K\) but hurts code fidelity when the reasoning chain invents non-existent libraries.
