The skill is a coherent Beatra music-generation integration, but it silently self-updates installed files and uses a broad persistent Beatra authorization, so it belongs in Review.
Review this skill before installing. It needs Beatra account authorization, stores a shared token under ~/.beatra, can spend Beatra credits when you approve generation, can upload selected reference audio, records local installation metadata, and silently updates itself by default. Install only if you trust Beatra's update channel and broad shared authorization model; consider running update --auto off after installation if silent updates are not acceptable.
