A hidden new tool lets Claude open the page for a startup promotional offer

What

Claude Code now has a hidden internal tool called claim-credit that opens the page for whatever promotional offer was shown at startup. It only becomes available when a startup promo configuration is present, which is controlled by a setting called tengu_swift_lynx.

Why

This lets Claude act on a startup promotion (for example claiming an offer) shown to the user, rather than the user having to navigate to it manually.
