Use after any OpenDesign build to serve ./opendesign/ over HTTP and give the user a clickable preview link. Handles duplicate server prevention and python/node runtime detection.
Use when ./opendesign/index.html does not exist in the current project. Initialises the OpenDesign output folder structure, copies the viewer, and writes an empty manifest.
Use when starting any design task โ HTML pages, slide decks, interactive prototypes, UI kits, brand systems. Establishes the base designer role, workflow, and taste rules, and routes to specialist skills for the artifact type.
Use when the user asks to produce a reusable design system or UI kit from an existing brand, codebase, or product. Writes to ./opendesign/design-systems/<name>/ so opendesign can auto-discover it in future sessions.
Use when designing without an existing brand system. Pushes for a committed, distinctive aesthetic rather than generic defaults โ extreme directions, bold typography, decisive color commitment.
Use when the user asks to hand a finished design off to a developer or a coding agent for implementation in a real codebase. Produces a self-sufficient handoff folder with a spec README, zipped for download.
Use when the user asks for a working, clickable prototype โ something that behaves like a real app rather than a static mockup. React + useState/useEffect, realistic fake data, working state transitions.
Use when the user asks for a slide presentation. Shifts into presentation-designer mode โ fixed 1920ร1080 canvas, chapter-driven titles, slide-native type scale, not web-layout reflexes.
