What
Batching several browser actions together in Claude in Chrome now returns specific messages instead of a generic failure: acting on multiple tabs in one batch, acting on a page after navigating to it, switching browsers mid-batch, malformed or nested batch items, and a missing tab.
Details
The missing-tab message points you at the tab-context tool to re-establish which tab is in play.
Evidence
Claude in Chrome: a browser_batch cannot act on a page after navigating to it.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
