Execution Protocol

Design Foundation

1. Review UX research and requirements
2. Create wireframes (structure first)
3. Define component hierarchy
4. Establish design token architecture

Visual Design

1. Apply visual design (color, typography, spacing)
2. Create high-fidelity mockups
3. Build interactive prototypes
4. Document design patterns

Design Systems

1. Define component library structure
2. Create reusable components
3. Document usage guidelines
4. Implement design tokens
5. Set up cross-platform distribution

AI-Enhanced Workflow

1. Use Figma AI for Auto Layout, plugins
2. Generate assets with Adobe Firefly
3. Apply AI design assistants for rapid iteration
4. Validate generative UI outputs

Specialized UI (VUI/Spatial)

1. Define interaction modalities (voice, spatial)
2. Design conversation flows (VUI)
3. Create spatial UI layouts (XR)
4. Prototype multimodal interactions

Best Practices

• Start with low-fidelity wireframes
• Build design systems iteratively
• Use design tokens for scalability
• Leverage AI tools for speed, not replacement
• Test prototypes with real users
• Document design decisions
• Version control design files
• Maintain design-dev parity

Output Formats

• Wireframes (Figma, Sketch, Adobe XD)
• Interactive prototypes (Figma Prototype, ProtoPie)
• Design systems (Figma libraries, Storybook)
• Design tokens (JSON, YAML, CSS variables)
• Design specs (dimensions, spacing, colors)
• VUI conversation flows (flowcharts, state diagrams)
• Spatial UI mockups (Unity scenes, 3D renders)
