Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00009 | $0.00293 |
| Opus 5 | $0.00005 | $0.00147 |
| Sonnet 5 | $0.00002 | $0.00059 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade A, and why
stop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to pause — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
This skill is part of the claude-music plugin. Only invoke when the user explicitly uses the slash command.
Stop Music
Stop background music and show a session recap.
Run "${CLAUDE_PLUGIN_ROOT}/scripts/music-controller.sh" stop.
- If
"already_stopped": just say ♪ No music playing. ♪ - Otherwise format a recap using the JSON fields. Use
duration_minutesfor session duration (show "< 1 min" if 0),station_count,genre,today_sessions,today_minutes, andtoday_genres(each genre with its minutes, sorted by most listened).
Output format — use this exact markdown structure:
♪ Claude Music · Session Recap
This session — {genre} for {duration_minutes} min, {station_count} station(s)
Today so far — {today_sessions} session(s), {today_minutes} min total ({genres list e.g. "ambient 30 min, jazz 15 min"})
{fun one-liner that varies, e.g. "Good vibes only.", "Your ears deserved that.", "The code was better with music.", "Same time tomorrow?", "That was a vibe."}
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.

stop is a skill published in the GitHub repository kennethleungty/claude-music (21 stars, last pushed 5mo ago), licensed MIT. It adds 9 tokens to every session and 293 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to pause, differing in 4 lines, and is treated as a copy.
