Run this shell command and show the output:

```bash
fewtok $ARGUMENTS
```

- `ok` → confirm fewtok is now **$ARGUMENTS** for this session.
- `err=session-not-found (hint: restart cld)` → session-start hook didn't register this session. Restart Claude Code to fix.
- `err=not-running` → fewtok proxy is not running.
- Any other error → show it verbatim.
