[synthesis] Chain of Thought outputs polluting final structured response or being hidden when needed for debugging

For GPT-4o, explicitly separate CoT from the final answer using a delimiter \(e.g., 'Think inside tags, then output the answer'\). For Claude, use the explicit tool-use or step-by-step prompt but parse out thinking tags. For Gemini, instruct it to skip safety justifications in the CoT.

Journey Context:
CoT is essential for complex reasoning, but models handle the output differently. GPT-4o mixes thoughts and answers, breaking JSON parsers. Claude hides thoughts, making debugging hard. Gemini bloats thoughts with safety, wasting tokens. The synthesis is that you must enforce a strict structural delimiter for CoT in the prompt, and parse model-specific tags, to reliably separate reasoning from the final payload.
