Reactive Nostr SDK for TypeScript and JavaScript built on RxJS and a single in-memory EventStore. Use whenever the user is building or modifying a Nostr client, working with NIP events/filters/pointers, subscribing to relays or pools, managing accounts/signers, loading events, publishing/replying/reacting/following, rendering note content, working with NIP-17/44/46/57/60/65, or wiring reactive React UI over Nostr data. Prefer this skill any time the user is in a TS/JS Nostr context, even if they have not named applesauce explicitly.
