One tab. One boundary.

TabRelay exposes only the browser tab you connect. Your connection ID selects that boundary for the current AI session.

A direct route to the tab you chose.

The public relay routes each request to the extension connection that owns the ID.

Route through TabRelayThe relay forwards requests without reading tab content.
Work from your AI clientThe CLI keeps output compact and scoped to that tab.
Connection isolation

Tabs stay in their own lane.

The extension resolves a connection ID to its local tab. A request for Tab A cannot silently fall through to Tab B.
