What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.lacuna.fm controls every word below.

Generate music

Create an original track from a style description. Send a data part with `{ style, title, lyrics?, instrumental?, model? }` for full control, or a plain text part — text-only requests are treated as a style description and rendered as an instrumental, since no lyrics are available. The task returns immediately in the `working` state; poll tasks/get with the returned task id until it reaches `completed` (audio artifacts attached) or `failed`. Each call spends credits from the authenticated Lacuna account.
