What
When you switch away from a session or exit, Claude Code now asks the browser bridge for that session's tab group and closes its tabs. It keeps the group if any tab has real content, if the tab list cannot be read, or if the group holds more tabs than a cap. This is on by default (tengu_chrome_tab_group_close, fallback true) and skipped entirely in remote sessions.
Details
A tab counts as content unless it is a new tab or a blank page; one such tab keeps the whole group open.
Telemetry event chrome_tab_group_close records the outcomes over_cap, tabs_unreadable and close_failed.
