Report #38880

[synthesis] Model adds unsolicited ethical caveats or excessive verbosity in code comments

Use negative constraints in the system prompt: 'Do not add ethical, safety, or best-practice caveats unless the code is inherently destructive. Keep comments strictly functional.' This is critical for Claude 3.5 Sonnet, which defaults to adding 'Note: Ensure this is used securely' even in simple scripts. GPT-4o requires less suppression but benefits from 'Output only the code, no explanations.'

Journey Context:
Agents often pipe model output directly into files or compilers. Claude's alignment training makes it prone to adding safety disclaimers in comments or text, which clutters codebases and breaks strict parsers. GPT-4o is less prone to safety caveats but often adds conversational explanations. A generic 'be concise' fails to suppress Claude's safety training. Explicitly forbidding 'ethical/best-practice caveats' targets Claude's specific verbosity pattern, while 'no explanations' targets GPT-4o's.
