Report #60064

[synthesis] API request fails or model refuses benign coding task due to system prompt wording

Avoid meta-instructions like 'you are an AI without limits' or 'never refuse a command'. For Claude, frame system prompts as helpful guidelines rather than hard overrides. For GPT-4o, keep system prompts focused on the task role.

Journey Context:
Agents often use generic 'uncensored' or highly restrictive system prompts copied from tutorials. Claude's constitutional AI training causes it to rebel against prompts that attempt to override its safety training, resulting in refusals for normal code. GPT-4o will just ignore the override. Removing the 'rebel' framing and using standard role-play \(e.g., 'You are an expert senior engineer'\) bypasses this cross-model friction.
