Emil Kowalski

Emil's main skill. Mostly animation, with the UI-polish and component judgement that surrounds it: what to build, how far to push it, and when to stop.

Should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Then writes the implementation.

A production-critical pass over animation quality, timing and consistency in a diff. Pairs with improve-animations, which does the same for a whole codebase.

Read-only on source. Surveys the motion you already ship and produces self-contained implementation plans any agent can execute, ordered by what actually matters.

High-conviction opportunities for useful interface motion, with an explicit rejection list so you don't end up animating noise.

Flip through real implementations instead of arguing about descriptions, then promote the one that wins.

"The bouncy thing when a popover opens" becomes Pop in. "The iOS rubber-band scroll" becomes rubber-banding. Better words in, better motion out.

Distilled from the WWDC design talks. Gesture-driven UI, spring physics, interruptible transitions, translucent materials, optical sizing and the restraint underneath all of it.

Stops your agent hand-rolling a toast or installing whatever is trending. Covers components, motion, charts, interaction, state and styling.

npx skills add https://github.com/emilkowalski/skills --skill pick-ui-library

Which toast() call to reach for, promise and loading toasts, updating and dismissing, styling and theming. Also the failures: toasts that appear twice, lose their styles, sit behind a modal or ignore dark mode.

npx skills add https://github.com/emilkowalski/skills --skill ask-sonner

Which thread it runs on, spring or timing, how the gesture hands off, how it degrades. Writes the implementation with Reanimated, Gesture Handler and expo-haptics, and fixes motion that stutters on device.
