  async create_playlist(args: Record<string, unknown>) {
    if (!cfg.spotifyClientId || !cfg.spotifyClientSecret) throw new Error("SPOTIFY_CLIENT_ID/SECRET are not configured");
    const userId = String(args.user_id || "");
    const name = String(args.name || "");
    if (!userId || !name) throw new Error("user_id and name are required");
    return client.createPlaylist(userId, name);
  },

• src/apis/spotify/spotify.ts:98-106 (registration)

      type: "object",
      properties: { user_id: { type: "string" }, name: { type: "string" } },
      required: ["user_id", "name"],
