name: typeui-fundamentals description: Universal UI/UX design principles covering visual hierarchy, interaction laws, typography foundations, and WCAG accessibility requirements. Use when making design decisions not covered by a specific design system, validating principle compliance, or resolving conflicts between aesthetics and accessibility. Design-system-agnostic and applies to every surface. license: MIT metadata: author: typeui.sh

Design Fundamentals — Agent Instructions

Universal design principles that define why patterns work, how to apply them correctly, and what accessibility requirements are non-negotiable. These are timeless, design-system-agnostic foundations that apply to every surface regardless of vertical or workflow phase.

Load order

Read these files after loading the design system (SKILL.md / DESIGN.md + token modules). The design system tells you what token to use; these files explain why that decision is correct and how to avoid common principle violations.

Module index

File	Purpose
ui-principles.md	Universal visual design principles — hierarchy, layout rhythm, typography placement, color theory, depth & layering, interaction design, responsive adaptation, component behavior
spacing-principles.md	Spacing-specific principles — 4-point grid, proximity grouping, inner vs outer gaps, vertical and horizontal rhythm, heading→paragraph spacing, section and component spacing tiers
ux-principles.md	Interaction & control principles — 30 UX laws, button/control state contracts (9 states), hover/active technique palettes, touch targets, cognitive load, feedback loops
typography-principles.md	Typography-specific principles — type system foundations, scale & modular ratios, readability & measure, accessibility, responsive type, brand tone expression through type
accessibility.md	WCAG 2.1/2.2 compliance — contrast ratios, color-as-information rules, focus visibility, keyboard navigation, motion safety, target sizes, text spacing, semantic structure, ARIA

What these files are NOT

These files do not define:

Workflow phases (think → build → check → ship) — see skills/vertical/SKILL.md
Quality gates or audits — see skills/vertical/inspect.md, review.md, preflight.md
Anti-pattern catalogs — see skills/vertical/anti-patterns.md
Industry-specific content — see skills/vertical/team-social-saas.md
Design tokens or component specs — see skills/design-system/SKILL.md

Conflict resolution

When sources disagree:

Design system wins for concrete values (colors, sizes, spacing tokens, component specs).
Fundamentals (this layer) win for structural principles (hierarchy, accessibility, motion logic).
Vertical wins for process decisions AND content architecture (section order, required sections, industry tone).

Accessibility is non-negotiable at every level — it overrides aesthetic preferences everywhere.

When the design system is silent, these principles decide

Any design decision not covered by the system's tokens or component rules falls back to the principles here. Never contradict the design system — if a principle and a design-system rule conflict, the design system wins. Flag the conflict for review.
