# --- 3. Glass-mode note -----------------------------------------------------

cat <<'NOTE'
Cursor's "Glass" UI mode has a hard-coded allowlist that blocks third-party
extensions like AgentWait from activating. To use AgentWait you must run Cursor
in classic mode:
    cursor --classic /path/to/your/project
