Music

What it does

When your agent uses it

• Creating instrumental tracks
• Songs with lyrics
• Background music
• Any AI-generated music composition

Example prompts

• “/music”

Requirements

• Python 3
• A credential in ELEVENLABS_API_KEY
• Compatibility (from SKILL.md): Requires internet access and an ElevenLabs API key (ELEVENLABS_API_KEY).

What it can do on your machine

Read from SKILL.md and the folder at commit 452e950. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.elevenlabs.io

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • ELEVENLABS_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires internet access and an ElevenLabs API key (ELEVENLABS_API_KEY).

  From compatibility in the SKILL.md frontmatter.

Context cost

Music loads about 827 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 123 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~70

When it runs · the whole SKILL.md, loaded when a task matches

~827

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
