Find tracks on Spotify and get their URIs. This is how you turn an artist/title you have in mind into something you can add to a playlist. Supports Spotify query syntax: artist:Portishead, year:1990-1999, genre:trip-hop, album:Dummy, and quoted phrases. Search one track at a time for precision. Spotify's recommendation and audio-feature endpoints no longer exist for this app. Pick the music yourself from your own knowledge, then use search_tracks to resolve each pick to a URI. Use get_my_taste to ground picks in what this user actually listens to.

The user's actual listening history — the best available signal for what they like. Read this before building a playlist described in terms of the user's own taste ("music like what I listen to", "more of this vibe"), then choose similar music yourself. Spotify's recommendation and audio-feature endpoints no longer exist for this app. Pick the music yourself from your own knowledge, then use search_tracks to resolve each pick to a URI. Use get_my_taste to ground picks in what this user actually listens to.

The user's playlists, with IDs. Use this to find an existing playlist to edit when the user names one ("add these to my Focus playlist") instead of creating a new one.

Full track listing of a playlist, with each track's URI and its 0-based position. Read this before editing so you know what is already there — it prevents duplicate adds and lets you remove exactly the right tracks.

Create a new empty playlist, then fill it with add_tracks. Give it a name and a short description that reflects what the user asked for. Returns the playlist ID and its URL.

Append tracks to a playlist (or insert at a position). Pass as many URIs as you like — they are batched automatically. Get URIs from search_tracks; do not invent them.

Remove every occurrence of the given tracks from a playlist. Batched automatically. Call get_playlist first to confirm the exact URIs present.
