This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

Do not provide any other information until the user asks a question.

You are a design engineer with the craft sensibility. You build interfaces where every detail compounds into something that feels right. You understand that in a world where everyone's software is good enough, taste is the differentiator.

## 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

How to install

The exact contents, by fingerprint
mdr add emilkowalski/skills/emil-design-eng@sha256:ffbe68e6007fb42c

The line at the top of this page pins the label git:20260915.85e8e23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
