Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00095 | $0.01776 |
| Opus 5 | $0.00048 | $0.00888 |
| Sonnet 5 | $0.00019 | $0.00355 |
| Haiku 4.5 | $0.00010 | $0.00178 |
Grade A, and why
lyria 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 7d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lyria Music Generation Skill
Generate high-fidelity 44.1 kHz stereo audio, full songs with structured lyrics, instrumental soundtracks, and thematic compositions from text prompts or visual reference images using Google's Lyria 3 foundation models (lyria-3-clip-preview and lyria-3-pro-preview).
Available scripts
scripts/lyria.py: CLI tool for text-to-music and image-to-music generation, lyric export, and audio format conversion.scripts/test_lyria.py: Test suite verifying Lyria argument parsing and multimodal input limit enforcement.
Trigger Conditions
Activate this skill whenever the user asks to:
- Generate music, songs, soundtracks, game audio beds, or background music.
- Compose musical themes inspired by artwork, concept photos, or screenshots.
- Create 30-second audio loops or multi-minute structured songs with verses, choruses, and custom lyrics.
- Synthesize instrumental audio tracks (
"Instrumental only, no vocals").
Model Selection & Comparison Matrix
| Model | Model ID | CLI Name | Primary Use Case | Duration | Audio Format | Reference Guide |
|---|---|---|---|---|---|---|
| Lyria 3 Clip | lyria-3-clip-preview |
clip |
Short clips, loops, previews, rapid style testing | Exactly 30s | MP3, WAV | lyria-3-clip.md |
| Lyria 3 Pro | lyria-3-pro-preview |
pro |
Full songs, multi-section arrangements, film scoring | Up to 184s | MP3, WAV | lyria-3-pro.md |
Model Selection Guide
- Rapid Prototyping: Start with Lyria 3 Clip (
clip) to iterate quickly on genre combinations, tempos, and instrumentation. - Full Song Production: Select Lyria 3 Pro (
pro) when requiring timestamped transitions ([0:00 - 0:15] Intro...), multi-verse vocal delivery, or multi-minute thematic development.

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
