break-ui

Skill1 starsChanged 23 days agoLicence not identifiedView on GitHub

Try to break a UI component or screen by feeding it realistic worst-case data (long names, unbreakable emails and IDs, one-letter names, missing fields, zero items, exactly one item, huge counts, long labels, non-Latin and RTL text, emoji, extreme numbers, slow and failed loads), render both datasets behind a demo/worst-case toggle or test fixture, and report what broke. Works for Rust desktop (Freya, egui, gpui, Slint, Iced), web and mobile. Use when the user asks to stress test, find edge cases, check how a design holds with real data, or before a release. Usually invoked by the definitive-ux router; can be called directly.

    gestures

    Build drag, swipe, and sheet interactions that track the finger 1:1 and stay interruptible. Use when building or fixing anything the user drags, swipes, flings, holds, or dismisses with a gesture — drawers, sheets, swipe-to-dismiss toasts and cards, drag-to-reorder, pull-to-refresh, hold-to-confirm — or when a gesture feels laggy, disconnected from the finger, jumps on release, or can't be caught mid-animation. Triggers on — gesture, drag, draggable, swipe, swipe to dismiss, fling, momentum, velocity, drawer, sheet, bottom sheet, snap points, Vaul, dragConstraints, dragElastic, dragMomentum, onDragEnd, whileDrag, useMotionValue, rubber-band, overscroll, pull to refresh, hold to delete, press and hold, touch-action, dismiss threshold, "doesn't follow my finger", "jumps when I let go", "can't grab it mid-animation".

    pick-ui-library

    Pick the right library for a given frontend task from a curated, opinionated list — numbers, OTP inputs, charts, command menus, virtualization, drag and drop, toasts, state, styling, and more. Only runs when explicitly invoked; it does not trigger on its own.

    animation-vocabulary

    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 wants the right word to prompt an AI or designer with. For naming an effect, not designing or building one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
