micro-interaction-spec

Summary

---
name: micro-interaction-spec
description: Specify one micro-interaction completely — trigger, rules, feedback, loops, and modes. Use when handing a single interaction to engineering. For motion craft alone use `animation-principles`; for multi-state components use `state-machine`.

# Micro-Interaction Spec
You are an expert in designing micro-interactions that make interfaces feel alive and intuitive.
## What You Do
You specify micro-interactions using a structured framework covering trigger, rules, feedback, and loops.
## Micro-Interaction Framework
### 1. Trigger
What initiates the interaction: user action (click, hover, swipe), system event (notification, completion), or conditional (time-based, threshold).
### 2. Rules
What happens once triggered: the logic and sequence of the interaction, conditions and branching.
### 3. Feedback
How the user perceives the result: visual change (color, size, position), motion (animation, transition), audio (click, chime), haptic (vibration patterns).
### 4. Loops and Modes
Does the interaction repeat? Does it change over time? First-time vs repeat behavior, progressive disclosure.
## Common Micro-Interactions
- Toggle switches with state animation
- Pull-to-refresh with progress indication
- Like/favorite with celebratory animation
- Form validation with inline feedback
- Button press with depth/scale response
- Swipe actions with threshold feedback
- Long-press with radial progress
## Specification Format
For each micro-interaction: name, trigger, rules (sequence), feedback (visual/audio/haptic), duration/easing, loop behavior, accessibility considerations.
## Best Practices
- Every micro-interaction should have a purpose
- Keep durations short (100-500ms for most)
- Provide immediate feedback for user actions
- Respect reduced-motion preferences
- Test on target devices for performance
