Quick answerWhen a customer cites a competitor's AI agent transcript or stated terms as leverage, the agent should never verify, dispute, or match the claim on its own, since it has no way to confirm the screenshot is genuine, current, or representative of a real offer. The correct default is to acknowledge the request, decline to negotiate against an unverified third-party claim, and route it to a human with pricing authority if the account is worth a real look, while logging the claim itself as competitive intelligence regardless of outcome.
Why this is easy to get wrong
Teams tend to reach for a policy statement or a prompt instruction as the fix, when the real gap is usually structural: missing checks in the data or decision path, not a lack of good intentions in the system prompt. Treating this as a one-time launch decision instead of an ongoing operating discipline is the most common way it quietly regresses months after the original design review.

A practical framework
Start with the smallest, cheapest control that closes the most likely failure mode, then add layers only where the data shows you actually need them. A control that looks thorough on a whiteboard but never gets exercised in production is worse than a simpler one your team actually reviews on a set cadence. Write the review cadence down and put an owner's name on it, since a control with no named owner tends to drift out of date within a quarter.
For teams that have already solved a related but distinct problem, see how to actually benchmark your AI agent against competitors' agents, which shares some of the same underlying design pattern even though the two situations are not interchangeable.

Where this connects to the rest of your AI agent program
This is not a standalone decision. It intersects with how you already handle handling contradictory answers your own agent gives two customers, and the two should be reviewed together rather than owned by completely separate teams with no shared visibility into each other's changes.
FAQ
How is this different from someone claiming to negotiate on another customer's behalf?
That scenario is about verifying whether a person actually has authority to act for someone else's account. This scenario is about a legitimate account holder using an outside claim, real or fabricated, about a competitor's pricing or terms as pressure, which is a negotiating tactic question, not an identity or authorization question.
How is this different from two customers getting contradictory answers?
That is an internal consistency problem, your own agent giving different customers different answers to the same question. This is an external claim about a different company's agent entirely, which your agent cannot verify and should not try to adjudicate.
Should the agent just say no every time?
The agent should decline to act on the claim itself, but escalation is still worthwhile when the account is large enough that a real competitive threat deserves a human pricing conversation. Treat the claim as a lead for the account team, not evidence to accept at face value.
