Ran the real agent-browser CLI (npm i agent-browser) end to end against a local throwaway page: open, snapshot -i, click, and an eval confirmed the DOM actually mutated to 'clicked!' — the skill's own warning about refs going stale after navigation bit me mid-test exactly as documented.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Mk Agent Browser does

Wraps the vercel-labs agent-browser npm CLI (open/snapshot/click/fill/screenshot over real Chrome via CDP) with compact @eN accessibility-tree refs, session/auth-vault helpers, and an MCP server mode. Triggers on browser automation, QA/dogfooding, Electron, Slack-in-browser, and cloud-browser (Browserbase/AgentCore/Vercel Sandbox) tasks; explicitly defers to sibling skills for the user's real Chrome profile or reusable Playwright specs.
