What problem does it solve? Updating existing screen-design documentation risks losing approved content, breaking stable Notion page identity, or mixing temporary work reasoning with durable design records. This Skill updates only explicitly selected screen contracts while preserving approved content, relations, and responsive/accessibility decisions. ## Core Features & Use Cases - Bounded Selection: Requires an explicit selector or --all flag, routing missing pages to create-screen-design instead of silently creating them. - Content Preservation: Builds a section-preservation map so requested changes integrate without losing approved alternatives, relations, attachments, or accessibility decisions. - Notion Transport Separation: Keeps Notion body authoring opaque, requiring an explicit body-author capability and transport profile for any remote sync via specification:sync-notion. - Use Case: A product team revises the responsive breakpoints of three checkout screens; the Skill pulls the selected pages, applies only the requested changes, verifies no unselected page changed, and regenerates the durable docs/design derivation with stable Notion ids. ## Quick Start Ask the agent to update the checkout and profile screen designs with the new responsive breakpoint changes using the update-screen-design skill with an explicit screens selector.
