How the daily pick works
Each UTC day, ClaudSkills picks one skill from the top-quality bucket of the catalog via a deterministic date-hash. Install ClaudSkills to your home screen (see the install guide) and opt in below to get a daily push notification with the new pick.
Pool source for this date: daily_eligible. Catalog count at render time: see /stats/.

A short notification at 10:00 UTC each day with the new pick — works on Android Chrome (and any Android browser that supports Web Push).
