On the fourth of August a federal appeals court handed down a decision about a shopping bot, and almost everyone who read about it read about it as a legal story, which it is, and stopped there, which is the mistake. The Ninth Circuit overturned an injunction that had barred Perplexity from letting its agentic browser, Comet, shop on Amazon. Amazon had argued that Comet was essentially breaking into its platform, invoking the Computer Fraud and Abuse Act, the same anti-hacking statute that has been stretched over the years to cover an impressive range of things that are not hacking. The court was unpersuaded. It found Amazon unlikely to succeed on that claim, and the reasoning is the part worth your attention: the court said it was Perplexity's users, operating through their agents, who accessed Amazon. Not Perplexity. The user is the one at the door. The agent is just the hand.
This is the first time a federal appeals court has addressed whether an AI agent acting on someone's behalf can legally go where that someone could go. Lawyers will spend the next two years arguing about what it means for the CFAA, and they should, because it is genuinely unsettled and genuinely important. I am not a lawyer and I am not going to pretend the doctrinal question is my lane.
Here is my lane. For twenty years I have watched companies build the front of their business for a creature with eyes, a limbic system, and about eight seconds of patience. And a court just said, in effect, that a growing share of the creatures arriving at your storefront are going to be neither of those things, and that this is legal, and that the platform you are selling on does not get to stop it by calling it hacking.
The Persuasion Stack Assumes a Mammal
Think about what is actually on a product page. The hero image, shot at an angle chosen because it tested well. The urgency banner counting down to a deadline that resets every night. The review carousel, sorted to put the articulate five-star review first. The trust badges, which do nothing except exist in a place where trust badges are expected to exist. The color of the buy button, which somebody argued about for a full afternoon. The free shipping threshold set three dollars above the average basket, because that three dollars is the entire trick.
Every one of those things is a lever on a human nervous system. They work, mostly, and I have built and tested plenty of them and taken money for it. But they are all aimed at a specific target: a distracted primate with a credit card and an unexamined feeling about what a trustworthy website looks like.
An agent has no unexamined feelings. It has a constraint list. It has a budget ceiling, a delivery window, a compatibility requirement, and a tolerance for ambiguity of roughly zero. It does not experience your hero image. It cannot be nudged by a countdown timer, and if it can, that is a bug someone will patch. It will not be reassured by a badge that says Secure Checkout, because it can simply read the certificate.
What survives contact with that customer is a very short list: price, availability, specification, compatibility, shipping time, return terms. Facts, stated unambiguously, in a form a machine can lift without guessing. That is the whole surviving surface. Everything else in the persuasion stack is decoration for an audience that has left the room.
Before You Rebuild Your Website
Now, having said that, let me argue with myself, because I have spent the last year telling anyone who will listen that the AI search industry is running on vibes and I am not about to hand out a fresh set of vibes with my name on them.
Nobody knows what share of commerce is agent-mediated right now. Not Perplexity, not Amazon, not the consultant who is going to email you next week offering an Agentic Commerce Readiness Audit. It is small. It is almost certainly small enough that if you rebuilt your entire storefront around it this quarter you would be optimizing for a customer who does not exist yet, at the expense of the ones who do, which is the oldest and most expensive mistake in this business. I have written about why most of the current generation of AI-search strategy is premature optimization and this does not change that. A court ruling is not a demand curve.
So do not gut your site. That is not the lesson.
The lesson is quieter and, I think, more useful: the work that makes you legible to an agent is not new work. It is the work you were already supposed to have done. Clean, accurate structured data that matches what is actually on the page. Inventory status that is true at the moment it is read. Specifications in fields rather than baked into a JPEG. Prices that are not assembled by JavaScript three seconds after load. A return policy written in sentences instead of implied by a PDF. This is the same list I have been handing clients since long before anyone said the word agentic, and it is the same list that made sites work for screen readers, for Google's shopping feed, for the comparison engines, and for every partner integration you ever had to build in a hurry.
None of it was ever glamorous. It has always been plumbing. The difference now is that the plumbing has an audience that cannot see anything else.
What Actually Changed
What changed on the fourth of August is not that agents started shopping. They already were. What changed is that a platform tried to shut the door on them by calling it intrusion, and a federal appeals court said the door does not work that way, because the person on the other side is your customer and the agent is their hand.
If you sell things, that is a sentence worth sitting with. You do not get to refuse the format your customer arrives in. You never did, really. You did not get to refuse mobile in 2012 because your site looked better on a desktop. You did not get to refuse marketplace listings because you preferred your own checkout. Every time a new intermediary has appeared between a seller and a buyer, the sellers who did well were the ones who accepted the intermediary early, made themselves trivially easy to represent accurately, and stopped trying to win a fight about the shape of the channel.
So no, do not redesign for robots. Do go and check whether the price on your page is a number a machine can read, whether your stock status is true, and whether the specification a buyer would filter on is written down anywhere a parser can find it. Those are boring afternoons and they were overdue before any of this.
The agent will not be charmed. It will be satisfied, or it will be gone.
