Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.00733 |
| Opus 5.5 | $0.00025 | $0.00293 |
| Sonnet 5.5 | $0.00012 | $0.00147 |
| Haiku 4.5 | $0.00006 | $0.00073 |
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 1mo 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spotify
Control Spotify playback via the Spotify Web API.
When to Use
✅ USE this skill when:
- "Play some jazz music"
- "Skip this song"
- "What's currently playing?"
- "Search for songs by The Beatles"
- "Pause the music"
- "Add this song to my queue"
When NOT to Use
❌ DON'T use this skill when:
- Downloading or saving music → Spotify API doesn't support downloads
- Apple Music or YouTube Music → different APIs/tools
- Playing local audio files → use system media player
- Music recognition → use specialised tools (Shazam, etc.)
Setup
- Create a Spotify app at https://developer.spotify.com/dashboard
- Set redirect URI to
http://localhost:8888/callback - Get your Client ID and Client Secret
- Configure in
pythonclaw.json:
"skills": {
"spotify": {
"clientId": "your-client-id",
"clientSecret": "your-client-secret"
}
}
- Run the auth flow once to get a refresh token:
python {skill_path}/spotify_ctl.py auth
Alternative: spotify-player CLI
If you have spotify_player installed (Rust-based TUI):
brew install spotify_player # macOS
Then use it directly:
spotify_player playback play
spotify_player playback pause
spotify_player search "query"
Commands
Current playback
python {skill_path}/spotify_ctl.py now-playing
Search
python {skill_path}/spotify_ctl.py search "The Beatles" --type track
python {skill_path}/spotify_ctl.py search "Chill Vibes" --type playlist
Playback control
python {skill_path}/spotify_ctl.py play
python {skill_path}/spotify_ctl.py pause
python {skill_path}/spotify_ctl.py next
python {skill_path}/spotify_ctl.py previous
Play a specific track or playlist
python {skill_path}/spotify_ctl.py play --uri spotify:track:4iV5W9uYEdYUVa79Axb7Rh
python {skill_path}/spotify_ctl.py play --uri spotify:playlist:37i9dQZF1DXcBWIGoYBM5M
Queue a track
python {skill_path}/spotify_ctl.py queue spotify:track:4iV5W9uYEdYUVa79Axb7Rh
What ships with it
1 file 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.
- 1mo ago First seen · 125 lines · 62 tokens per session scan A 8a99097a8bb1
spotify is a skill published in the GitHub repository ericwang915/PythonClaw (45 stars, last pushed 10d ago), licensed MIT. It adds 62 tokens to every session and 733 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
