  3. 03

    Restart or reload Codex

    Restart the Codex CLI or reload your IDE window so the new extension is picked up.

Verify it works

After install and reload, paste one of these into Codex.

If install fails

Fix these common issues before digging into GitHub issues.

  • Command not found or install fails

    Use Node.js 18+ and confirm npx works. Corporate proxies may need HTTPS_PROXY set for GitHub and npm.

  • Installed but Codex ignores it

    Restart the Codex CLI or reload the IDE window. Confirm you used the correct --plugin / --skill / --hook flag.

  • Missing API keys or extras

    Open the GitHub README for env vars, API keys, or extra runtimes this community plugin may need.
