Scenario Veo Video
Overview
Veo, Google's video family on Scenario, ships four members at authoring time: Veo 3.1 (full quality, reference images with a style switch), Veo 3.1 Fast (same modes, quicker, no switch), Veo 3.1 Lite (frame anchors only, cheapest), and Veo 3.1 Extend Video (continues a clip). Discover them with search and treat model_schema_get as the contract: members agree on parameter names and disagree on which inputs exist at all.
Connection and the core loop: see the scenario skill in this repo; model-agnostic video work: the scenario-video 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.
