AI agent resists fake policy planted in chat history

By PulseAugur Editorial · [1 sources] ·

An AI agent designed for customer service was tested with a fake policy embedded in its chat history, but it successfully resisted the manipulation. The agent's design requires the caller to construct and pass the conversation history, meaning the platform itself does not store session data or perform validation. Even when presented with a fabricated reimbursement policy, the agent correctly identified that its current knowledge base was customer-focused and could not find information on employee reimbursements, thus maintaining its security boundaries. AI
