Apple HIG: Design Foundations
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
Prioritize content over chrome. Reduce visual clutter. Use system-provided materials and subtle separators rather than heavy borders and backgrounds.
Build in accessibility from the start. Design for VoiceOver, Dynamic Type, Reduce Motion, Increase Contrast, and Switch Control from day one. Every interactive element needs an accessible label.
Use system colors and materials. System colors adapt to light/dark mode, increased contrast, and vibrancy. Prefer semantic colors (label, secondaryLabel, systemBackground) over hard-coded values.
Use platform fonts and icons. SF Pro, SF Compact, SF Mono by default. New York for serif. Follow the type hierarchy at recommended sizes. Use SF Symbols for iconography.
Match platform conventions. Align look and behavior with system standards. Provide direct, responsive manipulation and clear feedback for every action.
Respect privacy. Request permissions only when needed, explain why clearly, provide value before asking for data. Design for minimal data collection.
Support internationalization. Accommodate text expansion, right-to-left scripts, and varying date/number formats. Use Auto Layout for dynamic content sizing.
Use motion purposefully. Animation should communicate meaning and spatial relationships. Honor Reduce Motion by providing crossfade alternatives.

Applying Foundations Together
Consider how principles interact:
Color + Dark Mode + Accessibility -- Custom palettes must work in both modes while maintaining WCAG contrast ratios. Start with system semantic colors.
Typography + Accessibility + Layout -- Dynamic Type must scale without breaking layouts. Use text styles and Auto Layout for the full range of type sizes.
Icons + Branding + SF Symbols -- Custom icons should match SF Symbols weight and optical sizing. Brand elements should integrate without overriding system conventions.
Motion + Accessibility + Feedback -- Every animation must have a Reduce Motion alternative. Motion should reinforce spatial relationships, not decorate.
Privacy + Writing + Onboarding -- Permission requests need clear, specific usage descriptions. Time them to when the user will understand the benefit.
Output Format
- Cite the specific HIG foundation with file and section.
- Note platform differences for the user's target platforms.
- Provide concrete code patterns (SwiftUI/UIKit/AppKit).
- Explain accessibility impact (contrast ratios, Dynamic Type scaling, VoiceOver behavior).
Questions to Ask
- Which platforms are you targeting?
- Do you have existing brand guidelines?
- What accessibility level are you targeting? (WCAG AA, AAA, Apple baseline?)
- System colors or custom?

When to Use
This skill is applicable to execute the workflow or actions described in the overview.
AGI Framework Integration
Adapted for @techwavedev/agi-agent-kit
Original source: antigravity-awesome-skills
Memory-First Protocol
Retrieve prior design decisions (color palettes, typography, spacing scales) to maintain visual consistency across sessions. Cache generated design tokens.
# Check for prior frontend/design context before starting
python3 execution/memory_manager.py auto --query "design system decisions and component patterns for Hig Foundations"
Storing Results
After completing work, store frontend/design decisions for future sessions:
python3 execution/memory_manager.py store \
--content "Design system: adopted 8px grid, Inter font family, HSL color tokens with dark mode support" \
--type decision --project <project> \
--tags hig-foundations frontend
Multi-Agent Collaboration
Share design decisions with backend agents (API contract changes) and QA agents (visual regression baselines).
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Implemented UI components — new design system with accessibility compliance (WCAG 2.1 AA)" \
--project <project>
Design Memory Persistence
Store design system tokens and component decisions in Qdrant so any agent on any platform (Claude, Gemini, Cursor) can retrieve and apply consistent styling.
