   I can reproduce this on macOS as well, after a clean Codex restart and reinstalling the bundled browser plugins.

   Environment:

   • Codex Doctor: v0.142.0-alpha.6 · macos-x86_64
   • macOS: 26.5.0
   • Bundled browser plugin versions: browser@openai-bundled 26.616.41845, chrome@openai-bundled 26.616.41845
   • Chrome extension: installed and enabled in Chrome Default profile
   • Chrome Native Messaging Host: present and valid for com.openai.codexextension
   • macOS permissions: Automation and Accessibility enabled for Codex / Brave / System Events where applicable

   Observed behavior:

   • mcp__node_repl.js_reset succeeds with js kernel reset
   • Any mcp__node_repl.js call fails before browser setup, even a minimal call:

   nodeRepl.write('ok');
   

   Error:

   tool call error: tool call failed for `node_repl/js`
   
   Caused by:
       Mcp error: -32602: js: codex/sandbox-state-meta: missing field `sandboxPolicy`
   

   Steps already tried:

   • Restarted Codex Desktop
   • Removed and reinstalled chrome@openai-bundled
   • Removed and reinstalled browser@openai-bundled
   • Restarted Codex Desktop again after reinstall
   • Verified full codex doctor with escalated/network access: network, WebSocket, auth, config, state DBs, and install are OK; only TERM=dumb is reported as a terminal-display issue

   Impact:

   • Browser/Chrome extension tooling cannot initialize because node_repl/js fails before it can contact Chrome, Brave, or the in-app browser.
   • This does not appear to be caused by Chrome/Brave extension setup or macOS privacy permissions.
