This skill should be used when building Mixin bots — loading keystores and constructing SafeUser (Go) / MixinApi (Node), JWT auth, session/spend key separation, sending messages (direct, group, text, post, app card, buttons), Blaze WebSocket loop at wss://blaze.mixin.one (Mixin-Blaze-1, gzip), conversations and group management, user search, bare user TIP PIN registration, OAuth third-party login, idempotency, message_id dedup, and the mixin-kit-go wrapper (Go-only).
