The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    NO copyrighted references: Never name specific compositions, artists, or songs — the API will block with PROHIBITED_CONTENT.

    line 64

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Music Generator (Google Lyria 3)

Generate music using Google Lyria 3 Pro / Clip (DeepMind) via Gemini API, save to CC Pages, and share.

Two models:

  • Lyria 3 Clip (lyria-3-clip-preview) — 30-second clips, fast iteration
  • Lyria 3 Pro (lyria-3-pro-preview) — full-length songs (1-3 minutes)

Usage

~/.claude/skills/music-generator/scripts/music-generate.sh "your music prompt"

Options

# Quick 30s clip (default)
~/.claude/skills/music-generator/scripts/music-generate.sh "a dramatic solo piano piece in C minor"

# Full-length song (1-3 min)
~/.claude/skills/music-generator/scripts/music-generate.sh "epic orchestral film score" --duration full

# Specify style, key, tempo
~/.claude/skills/music-generator/scripts/music-generate.sh "jazz trio" --style jazz --key "Bb major" --tempo 140

# Allow vocals (default: instrumental only)
~/.claude/skills/music-generator/scripts/music-generate.sh "pop ballad with singing" --vocal

# Custom output filename
~/.claude/skills/music-generator/scripts/music-generate.sh "ambient soundscape" --output my-ambient

# Combine options
~/.claude/skills/music-generator/scripts/music-generate.sh \
  "virtuoso solo piano, Late Romantic style, dramatic arpeggios and singing melody" \
  --duration full --key "C# minor" --tempo 72 --output concert-piece

Output

  • Audio saved to $CC_PAGES_WEB_ROOT/assets/music/ as MP3
  • Returns the public URL: $CC_PAGES_URL_PREFIX/assets/music/{filename}.mp3

Workflow

# 1. Generate music
URL=$(~/.claude/skills/music-generator/scripts/music-generate.sh "solo piano nocturne" --duration full)

# 2. Share URL or embed in HTML
echo "Listen: $URL"

Prompt Engineering Tips

  1. Use timestamps for structure: [0:00-0:25] slow intro, [0:25-1:00] build intensity, [1:00-1:30] climax
  2. Use Italian musical terms: Allegro, Pianissimo, Rubato, Con fuoco, Crescendo, Sforzando
  3. Specify instrumentation explicitly: "solo piano", "string quartet", "jazz trio with piano, upright bass, and brushed drums"
  4. NO copyrighted references: Never name specific compositions, artists, or songs — the API will block with PROHIBITED_CONTENT. Use generic style descriptions instead ("Late Romantic virtuoso piano", "bebop jazz")
  5. Repeat "NO vocals" for instrumental: Say "Instrumental only. NO vocals. NO singing." at least twice if you want pure instrumental
  6. Describe dynamics and emotion: "haunting and melancholic opening, building to a passionate fortissimo climax, then resolving with gentle pianissimo"

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
