DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.221

Browser tabs: Claude is told to close tabs it opened

You'll notice
Useful3 Signal0
Chrome & Browser

Claude now closes browser tabs it opened, so you get fewer stray tabs left behind.

What

The tabs_create_mcp description now includes explicit cleanup instructions, so browser sessions should accumulate fewer stray tabs.

Details
  • each created tab should be closed with tabs_close_mcp once the work is done
  • a tab is left open only when the user asked for it
Evidence

Tabs you create are yours to clean up

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
