What problem does it solve? Creating new screen designs often scatters work across temporary notes, ad-hoc Notion pages, and unversioned documents, making it impossible to trace which design is current or approved. This Skill establishes a governed workflow that keeps exploration temporary, synchronizes approved content through an explicit transport, and promotes durable design docs with full provenance. ## Core Features & Use Cases - Responsive design contracts: Captures layout, responsive behavior, interaction states, accessibility, and handoff notes per screen across web and mobile platforms. - Governed Notion synchronization: Pushes approved bodies through an explicitly selected body-author capability and transport profile, then verification-pulls the canonical ref before advancing local metadata. - Durable promotion with provenance: Promotes stable designs to versioned docs with Notion ids, source revisions, decision links, and supersession metadata. - Use Case: A product team needs a new checkout flow designed for web and mobile. The Skill materializes the spec context, drafts the screen contract with alternatives, obtains approval, creates the Notion page via the caller-selected body author, and promotes the durable design doc linked to its decisions. ## Quick Start Ask the agent to create a screen design for your product's checkout and settings screens, providing the work id, Notion template and parent refs, transport profile, and body-author selector.
