Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.02779 |
| Opus 5 | $0.00018 | $0.01389 |
| Sonnet 5 | $0.00007 | $0.00556 |
| Haiku 4.5 | $0.00004 | $0.00278 |
Grade A, and why
controlling-spotify scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Controlling Spotify
Control Spotify playback, search for music, and manage playlists using the Spotify MCP Server with full user account access.
When to Use
Invoke this skill when users request:
- Playing, pausing, or skipping music on Spotify
- Searching for songs, albums, artists, or playlists
- Creating or modifying playlists
- Viewing currently playing track or playback status
- Managing their Spotify library (saved tracks, albums)
- Queuing songs or albums
Prerequisites
CRITICAL: This skill requires user-provided credentials. The user must complete a one-time setup:
One-Time User Setup
-
Create Spotify Developer Application
- Go to https://developer.spotify.com/dashboard/
- Create an app and note the Client ID and Client Secret
- Add redirect URI:
http://127.0.0.1:8888/callback
-
Obtain Refresh Token
- User must run the helper script locally (see
references/setup-guide.md) - Script exchanges OAuth code for a long-lived refresh token
- Refresh token is saved as credential in skill configuration
- User must run the helper script locally (see
-
Configure Credentials
- Add three credentials to this skill:
SPOTIFY_CLIENT_ID: From Spotify Developer DashboardSPOTIFY_CLIENT_SECRET: From Spotify Developer DashboardSPOTIFY_REFRESH_TOKEN: From helper script output
Alternative: Credentials can also be provided via a Project Knowledge file. Ensure the file contains a
.envstyle block with the keys above. - Add three credentials to this skill:
Without these credentials, the skill cannot function. If credentials are missing, guide the user through the setup process detailed in references/setup-guide.md.
MCP Server Installation
The Spotify MCP Server must be installed in the compute environment. Use the provided installation script which handles cloning, patching, and building the server.
# Run the installation script
bash scripts/install-mcp-server.sh
MCP Server Configuration
Configure the MCP client to connect to the Spotify MCP server. Note the logic to support credentials from Project Knowledge.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

controlling-spotify is a skill published in the GitHub repository oaustegard/claude-skills (148 stars, last pushed yesterday), licensed MIT.
