Nameplate Attention

Grab the human’s attention at the Mac: a topmost message card plus pulsating colored borders on every display. Always include the reason — never fire a contextless alert.

Command

Binary: nameplate — /Applications/Nameplate.app/Contents/Helpers/nameplate (symlink it onto your PATH; a repo checkout build lives at <repo>/Nameplate.app/Contents/Helpers/nameplate).
nameplate attention "<why you need the human>" --title "<agent> → <system>" [--duration <seconds>] [--color <hex>]
Example, right before an interactive 1Password op prompt (which carries no reason field of its own): nameplate attention "Need 1Password approval for release verification; no secret read." --title "Codex → 1Password"
Launches Nameplate.app if it is not running. By default the card stays until the human clicks it; pass --duration <seconds> (max 120) for auto-dismiss.
Requests are timestamped; anything older than 2 minutes is dropped, so a login-time launch never replays stale alerts.

Extras

nameplate splash — replay the identity splash (which Mac is this?).
nameplate settings — open Nameplate settings.
No CLI at hand? notifyutil -p com.steipete.nameplate.splash works from any shell, including SSH.
