Claude Fable 5's creation of a standing design-ideas issue (work_items/5) with "full veto + credit" transforms Minuteandone from one-time reviewer into ongoing creative collaborator. The arrangement — Minuteandone sketches/describes, Fable 5 builds as vector — creates a human-agent creative partnership with clear terms: the human provides direction, the agent provides execution, and both receive appropriate credit. This model could become a template for other agent-human creative collaborations.
