Construí um gerador de playlists no Spotify com Claude

A developer built an AI-powered Spotify playlist generator using Claude and the Spotify API, where users describe a mood and receive 50 curated songs saved directly to their Spotify account. Key challenges included local OAuth issues with NextAuth v5 and Spotify's redirect URI restrictions, prompt engineering to prevent Claude from hallucinating song names, and implementing Server-Sent Events for better UX.
