Call `attach` first.'); const tabs: Array<{ index: number; url: string; title: string; active: boolean }> = []; let i = 0; for (const ctx of browser.contexts()) { for (const p of ctx.pages()) { tabs.push({ index: i, url: p.url(), title: await p.title().catch(() => ''), active: p === page, }); i++; } } return { tabs }; } - src/index.ts:353-357 (registration)Tool definition in the TOOLS array: name 'list_tabs', description 'List all open tabs across contexts.
