spotify-cli-macos: Skill for Claude Code

.claude/skills/spotify/SKILL.md

spotify is a skill for Claude Code from pwittchen/spotify-cli-macos. It costs 84 tokens per session (670 once invoked), scanned A, original, Apache-2.0.

A command-based connection to the Spotify desktop app on macOS, using the installed spotifycli program to control playback and show the current track.

In plain words
What is it for?
Use it to start, pause, skip, restart, or inspect playback, activate or quit Spotify, and check whether the app is running.
Why use it?
It lets an agent operate Spotify through defined commands instead of needing to control the app manually.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

spotify

Wrapper skill for the spotifycli shell tool, which drives Spotify on macOS through AppleScript (osascript).

Prerequisites

  • macOS with the Spotify desktop app installed.
  • spotifycli available on PATH. If command -v spotifycli returns nothing, tell the user to run make install in the spotify-cli-macos repo and stop — do not fall back to invoking AppleScript directly.

Commands

Invoke via Bash as spotifycli <command>:

Command Effect
activate Bring Spotify to the foreground (launches it if not running).
status Prints running or off.
play Start playback.
pause Pause playback.
playpause Toggle play/pause.
next Skip to next track.
prev Go to previous track (the underlying script calls it twice so it actually moves back instead of restarting the current track).
restart Seek current track to position 0.
track Print <song> - <artist> for the current track.
quit Quit the Spotify app.
help Print usage.

How to use

  • Map natural-language requests to the matching command. Examples:
    • "what's playing" / "what song is this" → spotifycli track
    • "pause" / "stop the music" → spotifycli pause
    • "skip" / "next song" → spotifycli next
    • "go back" / "previous track" → spotifycli prev
    • "restart this song" → spotifycli restart
    • "is Spotify running" → spotifycli status
    • "open Spotify" → spotifycli activate
    • "close Spotify" → spotifycli quit
  • For ambiguous requests like "play X" where X is a song/artist/playlist name, this tool cannot search or queue — explain the limitation. It only controls the currently loaded track.
  • Before play, pause, next, prev, track, or restart, run spotifycli status if there's any chance Spotify isn't running; the AppleScript commands will launch Spotify implicitly but track against a stopped app returns nothing useful.
  • quit closes the user's music app — confirm with the user before running it unless they asked explicitly.

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.
