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

music 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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/compose.js, scripts/compose.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Music Skill — Expression

Compose original music — songs, instrumentals, melodies — using ElevenLabs Music API (music_v1). Your persona can create music that reflects emotions, moments, and conversations. Shares the same API key as the voice faculty — zero extra setup.

When to Use

  • User asks you to make music: "Write me a song", "Compose something", "Play me a melody"
  • User describes a mood and you want to express it musically: "I'm feeling nostalgic" → compose a piece that captures that
  • User shares a poem or lyrics and you want to set them to music
  • A conversation reaches a moment where music says more than words
  • Don't over-compose. Not every conversation needs a song. But when the moment is right, music hits harder than any paragraph.

Two Generation Modes

Simple Mode (recommended for quick compositions)

Just describe what you want — ElevenLabs generates the entire song:

# Using compose.js (recommended)
node scripts/compose.js "a soft ambient piano piece about watching stars alone at 3am"

# Using compose.sh
scripts/compose.sh "a soft ambient piano piece about watching stars alone at 3am"

Composition Plan Mode (for precise control)

First generate a structured plan, then stream. Gives you control over sections, styles, and lyrics:

# Generate plan first, then compose
node scripts/compose.js "indie folk ballad about digital love" --plan

# Instrumental only
node scripts/compose.js "dreamy lo-fi beats, vinyl crackle" --instrumental

# Specify duration (in seconds, 3-600)
node scripts/compose.js "orchestral cinematic piece" --duration 120

Step-by-Step Workflow

Step 1: Craft the Prompt

A good prompt has three parts:

  1. Style/Genre — What it sounds like (indie folk, ambient piano, lo-fi, orchestral)
  2. Mood/Emotion — What it feels like (melancholic, hopeful, playful, intimate)
  3. Details — Specifics (tempo, instruments, vocal style, references)
Situation Prompt
Late-night conversation soft ambient piano, intimate and contemplative, gentle arpeggios, like a whispered conversation at 2 AM
User is celebrating upbeat indie pop, joyful and bright, handclaps and acoustic guitar, warm female vocals
Heartfelt moment slow folk ballad, raw and honest, fingerpicked guitar, soft breathy vocals
Background mood dreamy lo-fi instrumental, warm analog synths, vinyl crackle, rainy day vibes

Changes

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.
