Agent skills by Emil Kowalski that give coding agents design-engineering taste in animation easing, timing, and polish.

Emil Kowalski argues great AI-produced UI comes from taste, not secret prompts: people who know what a good interface looks like steer AI to it, and the quality bar rises as the work speeds up.
Emil Kowalski shipped an agent skill for animating React Native and Expo apps, covering gestures, sheets, haptics and screen transitions, built in collaboration with the Expo team.
Emil Kowalski's trick: point Fable at someone's publicly shared writing and have it distill their expertise into a reusable skill to consult before doing that kind of work.
Emil Kowalski on having a coding agent build several variants of a feature behind a switcher, with the chosen variant saved as a query parameter for easy sharing.
An argument for treating AI-generated open source libraries with suspicion: what made a dependency worth adopting was a person who shaped the API, wrote the docs, and knew why every line existed. Prompt-built libraries with generated READMEs now arrive daily and carry none of that signal.
Emil Kowalski on a practical inversion of agent prompting: for outputs an LLM cannot reproduce exactly, such as a dithered logo or a ripped punched-card texture, have the agent build a slider-driven generator and pick the result yourself. Control stays with the human, iteration gets faster.
