First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/openrouter-text2music/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

openrouter-text2music

Text → music via OpenRouter. Default model: google/lyria-3-pro-preview.

⚠️ This is a music-generation model, not TTS. It produces 48kHz stereo audio with instrumentation, and can include vocals and timed lyrics based on the prompt. For narration/voiceover, use a dedicated TTS tool (e.g., OpenAI tts-1, ElevenLabs).

Usage

Resolve TOOL_DIR = the directory containing this SKILL.md. Commands below use TOOL_DIR as a symbolic placeholder; replace it with the resolved, quoted path before running Bash.

export OPENROUTER_API_KEY=sk-or-v1-...

python3 TOOL_DIR/scripts/generate_music.py \
  --prompt "Driving synthwave, 120 BPM, nostalgic lead over a pulsing arpeggio, no vocals" \
  --download PROJECT_DIR/assets/bg_music.wav

Pricing

  • lyria-3-pro-preview: $0.08 per song

Notes

  • Request uses POST /api/v1/chat/completions with modalities: ["audio","text"].
  • Response parsing handles several shapes: message.audio, a content part with type=audio, or a data:audio/... URL embedded in the text content.
  • Output format is typically WAV (48kHz stereo); the script saves whatever bytes the API returns — choose the extension to match.
