Scenario ACE-Step Music
Overview
ACE-Step 1.5, a music production family on Scenario, splits every mode into its own model: Text to Music, Cover, and Repaint each in a Turbo and a Quality lane, plus a full-quality edit trio (Add Layer, Complete Track, Stem Extract), nine members at authoring time. Discover them with search, pick the member by mode name, and treat model_schema_get as the contract.
Connection and the core loop: see the scenario skill in this repo; model-agnostic audio work: the scenario-audio skill. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.
