Use to plan a mobile design system — tokens, spacing, typography scale, color palette, and reusable component primitives — before building screens. Establishes consistency; coordinates with theme, fonts, and accessibility.

Mobile Design System
Purpose
Establish a consistent visual foundation: design tokens, spacing/typography scales, color palette, and reusable primitives (buttons, inputs, cards) that screens compose from.
When to Use
- Before building multiple screens, to avoid ad-hoc styling.
- When UI is inconsistent across screens.
- Not for a single throwaway screen.
Inputs
- Brand/design guidance or Figma (if any).
- Accessibility and platform constraints.
Discovery Questions
- Is there a design source (Figma/brand) to derive tokens from?
- What are the spacing, typography, and color scales?
- Which primitive components recur across screens?
- What accessibility contrast/sizing constraints apply?
Responsibilities
- Define design tokens (spacing, radius, color, typography).
- Define typography and spacing scales.
- Design reusable primitives (buttons, inputs, cards, layout).
- Coordinate theming (
mobile-theme), fonts (mobile-fonts), icons (mobile-vector-icons), and accessibility (mobile-accessibility).
Required Workflow
- Derive tokens from the design source (or define a sane default set).
- Set typography + spacing scales.
- Build primitive components from tokens.
- Wire theme + fonts + accessibility.
- Record the design system.
Decision Rules
- Tokens are the single source of visual truth; components consume tokens, not hard-coded values.
- Prefer a small set of composable primitives over many one-off styled components.
- Meet accessibility contrast/target-size minimums from the start.
- Match platform conventions where users expect them.
Rules
- No hard-coded style values in screens — use tokens.
- Coordinate with theme/fonts/accessibility rather than duplicating them.
- Keep the primitive set small and composable.
Anti-Patterns
- Ad-hoc inline styles diverging per screen.
- A sprawling component library before screens need it.
- Ignoring contrast/target-size accessibility.
- Hard-coded colors/spacing bypassing tokens.
Validation Checklist
- Tokens defined.
- Typography + spacing scales set.
- Reusable primitives designed from tokens.
- Theme/fonts/icons/accessibility coordinated.
- No hard-coded style values in screens.
Definition of Done
A recorded design system: tokens, scales, and a small set of reusable primitives consumed via tokens — coordinated with theme, fonts, icons, and accessibility.

Context Loading Guidance
- Requires: design source (if any), accessibility constraints, recurring UI.
- Does not require: the whole app source, unrelated references, every mobile skill.
- May load:
mobile-theme,mobile-fonts,mobile-accessibility. - Stop when: the design system is recorded.
Token Efficiency Guidance
Derive tokens once; reference them. Keep the primitive list concise; link screen references instead of pasting UI.
