   This issue doesn't fully meet our contributing guidelines.

   What needs to be fixed:

   • The screenshot link appears to be a placeholder (https://github.com/user-attachments/assets/example) rather than a real attached image. Please attach an actual screenshot or remove the screenshot section if one isn't available.

   Please edit this issue to address the above within 2 hours, or it will be automatically closed.

   This issue might be a duplicate of existing issues. Please check:

   • Bash tool hangs on Windows when command spawns detached child processes (e.g. playwright-cli) #24731: "Bash tool hangs on Windows when command spawns detached child processes (e.g. playwright-cli)" — very similar symptom (Windows, browser automation tool hanging indefinitely), same suspected root cause (Windows Job Object / process group not releasing when child processes are detached)

   If you believe this was flagged incorrectly, please let a maintainer know.

   Based on my observations, when agent-browser is executed for the first time (for example, agent-browser open http://example.com), it spawns a background daemon process and the main CLI process exits successfully.

   However, OpenCode still keeps waiting for the command to finish. My guess is that the background daemon process may still be holding inherited stdio/pipe handles from the parent process.

   If the daemon is already running, agent-browser commands work normally in OpenCode.

   PR #29831 fixes this by completing spawn on 'exit' event instead of only 'close'. This solves the hang when agent-browser spawns a daemon that keeps stdio pipes open. Multiple users have confirmed it works on Windows with PowerShell.
