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

vibe 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.

What it actually says

This skill is part of the claude-music plugin. Only invoke when the user explicitly uses the slash command.

Vibe

Auto-detect the right music based on what's happening in the current session. No user input needed — the DJ reads the room.

Instructions

You have the full conversation context. Pick the best music and play it in ONE step. Do NOT spawn an agent or delegate.

Step 1: Read the room and pick music

Read the genre metadata from sources.yml:

python3 -c "
import sys
try:
    import yaml
    with open('${CLAUDE_PLUGIN_ROOT}/config/sources.yml') as f:
        data = yaml.safe_load(f)
except ImportError:
    sys.exit(1)
for genre, info in data.items():
    print(f'{genre}:')
    for s in info.get('stations', []):
        tags = ', '.join(s.get('tags', []))
        print(f'  - {s[\"name\"]}: {s.get(\"description\", \"\")}')
        print(f'    tags: {tags}')
    print()
"

Using the tags and descriptions, match the session context to the best genre. Consider:

  • What the user has been working on (e.g. debugging, building a feature, reviewing code)
  • The general mood/pace of the session
  • Any explicit mood signals from the user

When in doubt, lean towards relaxing genres (lofi, ambient, classical). The user prefers a chill atmosphere. Only pick high-energy genres if the session strongly suggests it.

Step 2: Play it

Pick a specific station name from the matched genre, then:

"${CLAUDE_PLUGIN_ROOT}/scripts/music-controller.sh" play "<station name>"

Step 3: Respond

Return a message in EXACTLY this format:

♪ Now playing {genre} — {station name}. {one-liner reason tied to the session} ♪

  • If takeover is true in the JSON output: prefix with Switched over from another session —
  • If error about no audio player: run the install_command (if has_sudo is true) or nosudo_hint (if false) from the JSON, then retry play automatically.

Keep it to one line. Do not explain your reasoning.

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.
