Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term ("the bouncy thing when a popover opens" → Pop in; "the iOS rubber-band scroll" → Rubber-banding). Use when the user asks "what's it called when…", or describes a motion effect without knowing its name and…

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading)…

Build, test, and end-to-end verify the Multiplex visionOS/iPadOS SSH-tmux terminal app. Use this whenever you need to compile the app, run its unit tests, regenerate the Xcode project after editing project.yml or adding/ removing source files, or confirm a change works in the real app on the visionOS or iPad…

This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.
Skill Claude CodeCodex
Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the…

Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.

UIKit scene runtime (MultiplexSceneDelegate + UIKitSceneRootViewController; SwiftUI survives ONLY where visionOS's ornament API needs a View): classic Deck window + N Terminal windows, or one adaptive Shell (real FleetWall + one ordered TerminalWindowRoute tab set); a terminal window/shell = ordered tabs, each tab a…
