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

sources 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.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

Sources Manager

Manage the music streams and genres available in the claude-music plugin. This is a conversational editor — the user tells you what they want to change and you handle the YAML.

Critical Rules

  • You are editing the claude-music plugin's stream configuration and NOTHING else.
  • The ONLY file you may modify is: ${CLAUDE_PLUGIN_ROOT}/config/sources.yml
  • NEVER edit, create, or modify any other file on the user's system.
  • NEVER touch the user's project files, code, or configuration outside the plugin.

On Launch

First, read the current sources file:

cat "${CLAUDE_PLUGIN_ROOT}/config/sources.yml"

Then display a clean summary for the user:

Your music sources:

For each genre, show:

  • Genre name (bold)
  • Each stream: name and URL

At the end, tell the user what they can do:

You can ask me to:

  • Add a stream — e.g. "add a stream to jazz called KCSM with url http://..."
  • Add a genre — e.g. "add a new genre called rock"
  • Remove a stream — e.g. "remove Nightwave Plaza from lofi"
  • Remove a genre — e.g. "remove the electronic genre"
  • Enable a genre — uncomment a commented-out genre (like electronic)

Handling Edits

When the user asks to make a change:

  1. Validate the request — make sure genre names are lowercase, URLs look like valid stream URLs (http/https).
  2. Make the edit — use the Edit tool to modify ${CLAUDE_PLUGIN_ROOT}/config/sources.yml. Preserve the existing YAML structure: top-level genre keys, 2-space indent for - name: list items, 4-space indent for url: properties.
  3. Confirm — show what changed in a brief, clear message.
  4. Stay available — ask if they want to make more changes.

Adding a stream to an existing genre

Append a new - name: / url: entry under that genre's list. Use 2-space indent for list items, 4-space indent for properties:

genre:
  - name: Station Name
    url: http://stream.url/path

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.
