Spotify

Control the user's Spotify account via the Hermes Spotify toolset (7 tools). Setup guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/spotify

When to use this skill

The user says something like "play X", "pause", "skip", "queue up X", "what's playing", "search for X", "add to my X playlist", "make a playlist", "save this to my library", etc.

The 7 tools

  • spotify_playback
    — play, pause, next, previous, seek, set_repeat, set_shuffle, set_volume, get_state, get_currently_playing, recently_played
  • spotify_devices
    — list, transfer
  • spotify_queue
    — get, add
  • spotify_search
    — search the catalog
  • spotify_playlists
    — list, get, create, add_items, remove_items, update_details
  • spotify_albums
    — get, tracks
  • spotify_library
    — list/save/remove with
    kind: "tracks"|"albums"
Playback-mutating actions require Spotify Premium; search/library/playlist ops work on Free.

Canonical patterns (minimize tool calls)

"Play <artist/track/album>"

One search, then play by URI. Do NOT loop through search results describing them unless the user asked for options.
spotify_search({"query": "miles davis kind of blue", "types": ["album"], "limit": 1})
→ got album URI spotify:album:1weenld61qoidwYuZ1GESA
spotify_playback({"action": "play", "context_uri": "spotify:album:1weenld61qoidwYuZ1GESA"})
For "play some <artist>" (no specific song), prefer
types: ["artist"]
and play the artist context URI — Spotify handles smart shuffle. If the user says "the song" or "that track", search
types: ["track"]
and pass
uris: [track_uri]
to play.

"What's playing?" / "What am I listening to?"

Single call — don't chain get_state after get_currently_playing.
spotify_playback({"action": "get_currently_playing"})
If it returns 204/empty (
is_playing: false
), tell the user nothing is playing. Don't retry.

"Pause" / "Skip" / "Volume 50"

Direct action, no preflight inspection needed.
spotify_playback({"action": "pause"})
spotify_playback({"action": "next"})
spotify_playback({"action": "set_volume", "volume_percent": 50})

"Add to my <playlist name> playlist"

  1. spotify_playlists list
    to find the playlist ID by name
  2. Get the track URI (from currently playing, or search)
  3. spotify_playlists add_items
    with the playlist_id and URIs
spotify_playlists({"action": "list"})
→ found "Late Night Jazz" = 37i9dQZF1DX4wta20PHgwo
spotify_playback({"action": "get_currently_playing"})
→ current track uri = spotify:track:0DiWol3AO6WpXZgp0goxAV
spotify_playlists({"action": "add_items",
                   "playlist_id": "37i9dQZF1DX4wta20PHgwo",
                   "uris": ["spotify:track:0DiWol3AO6WpXZgp0goxAV"]})

"Create a playlist called X and add the last 3 songs I played"

spotify_playback({"action": "recently_played", "limit": 3})
spotify_playlists({"action": "create", "name": "Focus 2026"})
→ got playlist_id back in response
spotify_playlists({"action": "add_items", "playlist_id": <id>, "uris": [<3 uris>]})

"Save / unsave / is this saved?"

Use
spotify_library
with the right
kind
.
spotify_library({"kind": "tracks", "action": "save", "uris": ["spotify:track:..."]})
spotify_library({"kind": "albums", "action": "list", "limit": 50})

"Transfer playback to my <device>"

spotify_devices({"action": "list"})
→ pick the device_id by matching name/type
spotify_devices({"action": "transfer", "device_id": "<id>", "play": true})

Critical failure modes

403 Forbidden — No active device found
on any playback action means Spotify isn't running anywhere. Tell the user: "Open Spotify on your phone/desktop/web player first, start any track for a second, then retry." Don't retry the tool call blindly — it will fail the same way. You can call
spotify_devices list
to confirm; an empty list means no active device.
403 Forbidden — Premium required
means the user is on Free and tried to mutate playback. Don't retry; tell them this action needs Premium. Reads still work (search, playlists, library, get_state).
204 No Content
on
get_currently_playing
is NOT an error — it means nothing is playing. The tool returns
is_playing: false
. Just report that to the user.
429 Too Many Requests
= rate limit. Wait and retry once. If it keeps happening, you're looping — stop.
401 Unauthorized
after a retry
— refresh token revoked. Tell the user to run
hermes auth spotify
again.

URI and ID formats

Spotify uses three interchangeable ID formats. The tools accept all three and normalize:
  • URI:
    spotify:track:0DiWol3AO6WpXZgp0goxAV
    (preferred)
  • URL:
    https://open.spotify.com/track/0DiWol3AO6WpXZgp0goxAV
  • Bare ID:
    0DiWol3AO6WpXZgp0goxAV
When in doubt, use full URIs. Search results return URIs in the
uri
field — pass those directly.
Entity types:
track
,
album
,
artist
,
playlist
,
show
,
episode
. Use the right type for the action —
spotify_playback.play
with a
context_uri
expects album/playlist/artist;
uris
expects an array of track URIs.

What NOT to do

  • Don't call
    get_state
    before every action.
    Spotify accepts play/pause/skip without preflight. Only inspect state when the user asked "what's playing" or you need to reason about device/track.
  • Don't describe search results unless asked. If the user said "play X", search, grab the top URI, play it. They'll hear it's wrong if it's wrong.
  • Don't retry on
    403 Premium required
    or
    403 No active device
    .
    Those are permanent until user action.
  • Don't use
    spotify_search
    to find a playlist by name
    — that searches the public Spotify catalog. User playlists come from
    spotify_playlists list
    .
  • Don't mix
    kind: "tracks"
    with album URIs
    in
    spotify_library
    (or vice versa). The tool normalizes IDs but the API endpoint differs.
