# Codex Headsup Diagnose
Run the fast color-flash test:
```bash
~/.codex/hooks/headsup-codex-diagnose.sh
```
Only pass `--restart` if the user explicitly asks for a deep/full test:
```bash
~/.codex/hooks/headsup-codex-diagnose.sh --restart
```
This briefly changes the current iTerm2 tab color, then restores the previous state.
