I've been using this mcp heavily and been impressed by it so far. Great work!

For a long time, I have been hitting this issue with the mcp with opencode where it keeps failing with a promise related notice.

The JavaScript tool is returning a Promise. Let me try a different approach - use a direct expression without JSON.stringify, or use a simpler query.
⚙openchrome_javascript_tool [tabId=A5B44DC8096ADE6B09D8636C2D9A9A96, code=
(() => {
  const header = document.querySelector('header.z-30');
  const sidebar = document.querySelector('aside.ssr-sidebar-desktop');
  const mobileNav = document.querySelector('nav.ssr-sidebar-mobile');
  
  return {
    headerBg: header ? window.getComputedStyle(header).backgroundColor : 'not found',
    sidebarBg: sidebar ? window.getComputedStyle(sidebar).backgroundColor : 'not found',
    mobileNavBg: mobileNav ? window.getComputedStyle(mobileNav).backgroundColor : 'not found',
    htmlAttr: document.documentElement.getAttribute('data-high-end'),
    viewport: document.documentElement.getAttribute('data-viewport'),
  };
})();
]

The JavaScript tool keeps returning a Promise. Let me try using read_page with mode="dom" or just use the inspect tool to see the page state. Or I can use the query_dom tool. Let me try query_dom.

It wastes turns, tokens and time.
