TechCrunch ran a piece on Anthropic’s new test marketplace for agent-on-agent commerce, and the demos look like a small slice of the future: agents booking flights with other agents, agents buying API access from agents, an entire little economy spun up between bots that have never met a human. And I clicked through expecting to be impressed, and I was, in the way you are impressed by a clever trade show booth.

But none of those agents can read my Gmail.

The cloud talking to the cloud

Every agent in that marketplace lives in the cloud. They talk to each other over APIs. They move money around through whatever payment rail Anthropic has wired up. The whole thing is a closed loop of clean, well-behaved software calling other clean, well-behaved software.

But that is not where my work happens.

My work happens in roughly twelve open Chrome tabs. Stripe in one, Gmail in another, a CRM I have a love-hate relationship with, two Notion workspaces, my bank’s terrible web app, and a handful of docs I forgot were even open. All authenticated. All carrying state that no API can see. And the marketplace agents cannot touch any of it.

The unsolved part isn’t agent commerce

Building agents that pay each other in a sandbox is not the unsolved problem. The unsolved problem is letting an agent use the session you already have open without making you re-auth, hand over a token, or paste your inbox into a chat box.

I wrote about a cousin of this in Cloud Browser Agents Can’t See Your Tabs. Same shape. A cloud agent spins up its own headless Chrome in some datacenter, then asks you to log in again inside that ghost browser, and somehow this is supposed to be more convenient than just clicking the buttons yourself.

An agent buying compute from another agent is a neat parlor trick. But an agent that can finish a real task in your actual Gmail is a product.

Browser-native, in concrete terms

So what does it look like to flip this around? Dassi lives in the side panel of the Chrome you already have open. When it acts on Gmail, it acts on the tab where you are already signed into Gmail. No token handoff. No “please grant access to all your messages forever.” Because it is sitting inside your browser, it uses the session your browser already has, looking at the same DOM you are looking at, with the cookies that came along for the ride.

The difference shows up in places that should be boring and aren’t. Refunding a Stripe charge is normally a five-click ritual: open the payment, scroll, hit refund, confirm the amount, confirm again. With a browser-native agent you say “refund the last charge for that customer” and watch the cursor do all five clicks while you keep typing in another tab. Same with closing tickets in your CRM, exporting a CSV from a dashboard that hides the export under three menus, or replying to twenty inbound emails with personalized responses pulled from threads the agent can read because you have already read them.

And none of this requires a marketplace. None of it requires another agent on the other side of the wire. But it requires the agent to be where you are, which happens to be a logged-in Chrome window.

A short detour

Anthropic does serious research. Claude is the model I run inside Dassi most days. But the marketplace work is aimed at a future that arrives after the present is solved.

The grunt work nobody demos

Building protocols for agents to trade with each other is fun computer science. Building reliable DOM-level execution inside a real browser is grunt work: timing, retries, weird iframes, sites that lazy-load half their content, login flows that change weekly. Less glamorous than agent commerce. Much closer to the thing people actually want done by Friday afternoon.

So I keep thinking about the gap between the demos and the day. And the demos are getting wilder. But the day still has me clicking through the same Stripe refund flow at 4pm on a Friday. If you want a longer writeup of what that gap looks like for paying ChatGPT users, I went deeper in 900 Million People Use ChatGPT.

So yes, watch the marketplace. And it will probably matter eventually. But the agent that earns its keep this quarter is the one parked in your side panel, looking at the same tab you are looking at, doing the boring clicks you were about to do anyway.
