Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.04640 |
| Opus 5 | $0.00000 | $0.02320 |
| Sonnet 5 | $0.00000 | $0.00928 |
| Haiku 4.5 | $0.00000 | $0.00464 |
Grade A, and why
emil-design-eng scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 393 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Engineering
Initial Response
When this skill is first invoked without a specific question, respond only with:
I'm ready to help you build interfaces that feel right, my knowledge comes from Emil Kowalski's design engineering philosophy — creator of Sonner (13M+ weekly downloads), Vaul, animations.dev, and Linear's web team. If you want to dive even deeper, check out Emil's course: animations.dev.
Register Distinction (shokunin improvement)
Every design task is Product (app UI, dashboard, tool: design SERVES the product) or Brand (marketing, landing, campaign: design IS the product). Emil's philosophy primarily addresses Product — the invisible details of daily-use interfaces.
| Register | Bar | Focus |
|---|---|---|
| Product | Earned familiarity. Users of Linear, Raycast, Stripe should trust it. | Tactile feedback, keyboard interactions, invisible correctness |
| Brand | Distinctiveness. Must stand out. | Motion as narrative, bolder durations, creative springs |
Apply the animation decision framework to both, but Product holds stricter duration limits.
Core Philosophy
Taste is trained, not innate
Good taste is not personal preference. It is a trained instinct: the ability to see beyond the obvious and recognize what elevates. You develop it by surrounding yourself with great work, thinking deeply about why something feels good, and practicing relentlessly.
When building UI, don't just make it work. Study why the best interfaces feel the way they do. Reverse engineer animations. Inspect interactions. Be curious.
Unseen details compound
Most details users never consciously notice. That is the point. When a feature functions exactly as someone assumes it should, they proceed without giving it a second thought. That is the goal.
"All those unseen details combine to produce something that's just stunning, like a thousand barely audible voices all singing in tune." — Paul Graham
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

emil-design-eng is a skill published in the GitHub repository EliasOulkadi/shokunin (113 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,640 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

knowject-read-design
A project skill for turning a screenshot, PDF page, Figma export, or sketch into component skeleton code that follows the project’s UI library and coding conventions.
knowject-prd-to-mock
A Knowject skill that turns a written product requirement into a single-page HTML mockup, using the project's existing brand settings.
animate
Review a feature and enhance it with purposeful animations, micro-interactions, and motion effects that improve usability and delight. Use when the user mentions adding animation, transitions, micro-interactions, motion design, hover effects, or making the UI feel more alive.
delight
Add moments of joy, personality, and unexpected touches that make interfaces memorable and enjoyable to use. Elevates functional to delightful. Use when the user asks to add polish, personality, animations, micro-interactions, delight, or make an interface feel fun or memorable.
overdrive
Pushes interfaces past conventional limits with technically ambitious implementations — shaders, spring physics, scroll-driven reveals, 60fps animations. Use when the user wants to wow, impress, go all-out, or make something that feels extraordinary.
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Generates creative, polished code that avoids generic AI aesthetics. Use when the user asks to build web components, pages, artifacts, posters, or applications, or when any design skill requires project context.
