    interaction-design

    Apply interaction design (IxD) principles and frameworks to product and service design work. Use this skill when designing or evaluating interaction flows, micro-interactions, feedback mechanisms, affordances, mental models, component states, response time, animation and transitions, error recovery, input validation, task flows, or navigation patterns. Core audiences: product designers, UX designers, UI designers, service designers, and interaction designers working on digital products and services. Trigger on: interaction flow, micro-interaction, affordance, feedback design, state design (hover/focus/error/loading/empty), response time, transition, animation, mental model, task flow, user flow, navigation design, interaction spec, handoff annotation, gesture, input validation, error state, loading state, empty state, system feedback, signifier, design review, interaction audit, IxD principles.

Design System Patterns

Master design system architecture to create consistent, maintainable, and scalable UI foundations across web and mobile applications.

When to Use This Skill

  • Creating design tokens for colors, typography, spacing, and shadows
  • Implementing light/dark theme switching with CSS custom properties
  • Building multi-brand theming systems
  • Architecting component libraries with consistent APIs
  • Establishing design-to-code workflows with Figma tokens
  • Creating semantic token hierarchies (primitive, semantic, component)
  • Setting up design system documentation and guidelines

Core Capabilities

1. Design Tokens

  • Primitive tokens (raw values: colors, sizes, fonts)
  • Semantic tokens (contextual meaning: text-primary, surface-elevated)
  • Component tokens (specific usage: button-bg, card-border)
  • Token naming conventions and organization
  • Multi-platform token generation (CSS, iOS, Android)

2. Theming Infrastructure

  • CSS custom properties architecture
  • Theme context providers in React
  • Dynamic theme switching
  • System preference detection (prefers-color-scheme)
  • Persistent theme storage
  • Reduced motion and high contrast modes

3. Component Architecture

  • Compound component patterns
  • Polymorphic components (as prop)
  • Variant and size systems
  • Slot-based composition
  • Headless UI patterns
  • Style props and responsive variants

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
