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. The same algorithm runs on the mobile companion app, so the pick you see here matches the one in your phone's daily push.
Pool source for this date: daily_eligible. Catalog count at render time: see /stats/.
