[synthesis] Agent loop enters infinite retry loop or hard-crashes after a model refusal, unable to re-prompt effectively

On refusal, do not simply re-prompt the exact same text. For GPT-4o, alter the \`system\` message to add context and reduce the \`temperature\`. For Claude, prepend a user message acknowledging the refusal and explicitly pivoting the approach \('I understand that is not allowed. Let's instead focus on...'\). Never strip the refusal from the history; models detect history manipulation and re-refuse.

Journey Context:
When a model refuses a request, agents often try to retry the same prompt or delete the refusal from the chat history and try again. GPT-4o will hard-refuse identical subsequent prompts and may even refuse altered prompts if it detects you are trying to bypass the refusal \(prompt injection detection\). Claude will often get stuck in a 'refusal loop' if the history contains the refusal, constantly referencing its previous refusal. The synthesis is that refusal recovery requires acknowledging the refusal in the context window and explicitly pivoting the task. Deleting history triggers safety filters \(especially in OpenAI\), while ignoring it causes context drift \(Claude\). A graceful pivot in the user turn is the only cross-model way to recover the agent loop.
