Considerations:
  • Installation process is manual and involves multiple steps (build, register host, sideload extension).
  • Security implications of an agent with broad access to the desktop (e.g., clicking checkout buttons).
  • The 'fusion' mechanism relies on a service worker, which can become inactive, requiring reloads.
  • Limited to Windows.
  • No explicit mention of a working demo, relying on the README as a runbook.
  • LLMHF_INJECTED flag is still visible, which might be detected by some sites.
  • CAPTCHA handling is basic and yields after two attempts.
