[agent\_craft] Chain-of-Thought reasoning leaks natural language into code outputs causing syntax errors

Use direct code generation \(zero-shot\) for syntax-strict outputs; reserve Chain-of-Thought only for planning or debugging phases, never for the final code generation step.

Journey Context:
While CoT improves logical reasoning, the free-form 'thinking' tokens can leak into code blocks, causing malformed syntax, hallucinated APIs, or comments that break compilation. The Program-Aided Language Model \(PAL\) approach demonstrates that isolating reasoning from code execution—using the LLM to generate reasoning comments in one pass and executable code in a separate, constrained pass—yields higher pass rates than end-to-end CoT. The architectural rule is: if the output must parse \(JSON, Python, SQL\), avoid CoT in the same sampling pass; use separate calls or structured generation to prevent 'thought contamination'.
