+
+:::info
+The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
+:::
+
+# 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 &lt;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.
