Unclear It is not settled where the tool is registered or what switches it on, so it may not be reachable in this version.
What
A new tool, OfferChromeSetup, is defined. A tool is an action Claude can choose to take during a task. This one lets Claude offer you one-time setup of Claude in Chrome, so the task can use your own signed-in browser.
- It is meant for when a Claude in Chrome tool has reported that the browser extension is not connected and the task needs your browser.
- It shows a setup card asking "Set up Claude in Chrome?" and waits until you respond.
- It reports back
connectedornot_now. One finding also lists a third result,no_attempt_yet. - It is a deferred tool, meaning it is not loaded until it is needed.
One finding says the tool is enabled only when a server-side flag reads true from the server itself, and that its built-in default is off. The flag server returned off for this site's account and for an anonymous baseline, but no reading of the flag has been taken under this release yet. The findings did not trace whether Claude can call the tool yet.
Why
If it is switched on, Claude can ask you to connect Chrome in the middle of a task instead of failing when the extension is missing. You choose whether to set it up then or later.
