 Run these from the repository root, in this order, before you push:
 
 1. The shared gates, at the version the workflows pin:
-   `npx -y @cosyte/script-utils@0.1.4 no-emdash`, then the same with `claude-card` and
-   `agent-notes` in place of `no-emdash`.
+   `npx -y @cosyte/script-utils@0.1.4 no-emdash`, then the same with `claude-card` in place of
+   `no-emdash`.
