Emil Kowalski Skills — Setup Guide

Source: skills.sh (694.4K combined installs) GitHub: emilkowalski/skills Category: Design Engineering First Seen: August 13, 2026 sweep Quality Tier: 🟢 Production

Emil Kowalski is the creator of Sonner (the toast library) and vaul, and one of the most-copied voices in agent UI quality. His skill pack is the highest-signal design-quality layer on skills.sh: it teaches agents to recognize bad AI-generated UI, audit motion instead of sprinkling it, and pick the right library before writing a component. emil-design-eng is the flagship at 204.4K installs.


Installation

npx skills add emilkowalski/skills

Installs all 10 skills. Hermes: place the SKILL.md files under your agent's skills directory, or run inside any skills.sh-compatible agent (Claude Code, Codex, Cursor, Hermes, OpenClaw, Nous Research).

Core Skills

Skill Installs Use For
emil-design-eng 204.4K Fluid, tactile interface design — the core design-engineering doctrine
review-animations 97.6K Adversarial review of animation/motion code against craft bars
animation-vocabulary 85.1K Reverse-lookup glossary: vague descriptions → named motion primitives
apple-design 77.0K Apple's HIG-informed approach to fluid, physical interfaces
improve-animations 70.1K Senior-engineer pass over a codebase's animation and motion code
find-animation-opportunities 58.7K Scan a UI for places that should animate but don't
pick-ui-library 44.8K Choose the right frontend library for the task before building
prototype 34.0K Build multiple genuinely different UI versions of a piece
animate 16.8K Build an animation from scratch, making the decisions
ask-sonner 5.9K Sonner-specific component guidance

Prerequisites

  • A frontend project (React-based for most skills; ask-sonner requires Sonner)
  • Access to motion libraries (Framer Motion / Motion One) for animation skills

CorpusIQ Use Cases

  • UI quality gate for agent-built dashboards — run review-animations + improve-animations before shipping any agent-generated frontend, the same way anti-ui-slop gates visual design
  • Docs site polishfind-animation-opportunities on docs.corpusiq.io surfaces motion gaps in landing and onboarding flows
  • Design-vocabulary alignmentanimation-vocabulary gives team prompts shared language when briefing video/graphics work (pairs with the HyperFrames pipeline)

Limitations / Verification

  • Quality-tier judgement is subjective — the skills encode opinions, not measurements; treat verdicts as review feedback, not tests
  • Verify installation with ls ~/.claude/skills/ | grep -i emil or your agent's equivalent skills directory listing
