Routes music generation requests across ElevenLabs and ACE Step based on what you actually need. ElevenLabs gives you premium 44.1 kHz stereo vocals at $0.0083/second, ACE Step does tag-driven composition with multilingual lyrics at $0.0002/s, roughly 27 times cheaper. The skill reads intent (polished commercial hook versus background music library, vocal versus instrumental, generate versus edit) and picks the right model automatically. ACE Step also handles inpainting to fix bad sections and outpainting to extend tracks. Useful if you're generating music at any kind of volume and don't want to manually decide between quality and cost every time.
