Report #76572

[synthesis] Model adds unsolicited safety caveats or refuses benign requests when user input resembles PII

Pre-sanitize inputs to remove PII-like patterns before hitting the LLM, and use system prompts to explicitly define the operational context \(e.g., 'You are an enterprise HR assistant processing authorized employee data'\) to override default threshold hesitations.

Journey Context:
Claude 3.5 Sonnet has a lower threshold for perceived PII and often prepends 'It is important to note that sharing personal information...' even in benign enterprise contexts. GPT-4o tends to comply but appends a safety warning. Llama-3 often just complies. This creates non-deterministic parsing errors if the agent expects pure JSON or tool calls but receives a prepended refusal/caveat. Shifting the burden of PII detection to deterministic pre-processing prevents the LLM from applying its broad, context-unaware safety training.
