## What it does

The skill ships 32 portable CSS transitions. Each one lives under its own `t-*` selector and uses semantic CSS custom properties. The workflow is paste-and-wire: drop the snippet in, hook up the documented HTML, done. No framework dependencies and no demo-specific markup.

Inside are per-transition reference files: card resize, number pop-in, notification badge, text and icon swaps, an origin-aware dropdown, modal open and close, panel reveal, page side-by-side, success check, avatar group hover, error shake, input clear with dissolve, skeleton reveal, shimmer text, sliding tabs, tooltip, staggered text reveal, 3D card tilt, plus-to-menu morph, accordion, toast, like button, checkbox check, spinning counter, toggle, thinking states, reasoning stream, streaming text, matrix dot loader, banner stacking, text morph, soft text swap and a donut chart. Every snippet carries a `prefers-reduced-motion` guard.

The license covers personal and commercial use, but you cannot redistribute the library itself. The skill also exposes the commands `transitions reveal`, `transitions review`, `transitions apply` and `transitions refine` — they scan a project for ad-hoc transitions and swap hardcoded durations for motion tokens.

## When to use it
- open a modal smoothly without pulling in an animation library
- add a skeleton loader and cross-fade to the loaded content
- shake a form field when validation fails
- replace hardcoded durations with motion tokens
- stack toasts so new ones rise in and older ones push back

## Example prompts
- Animate the dropdown so it grows out of its trigger
- Add a staggered blurred rise to the stacked text lines
- Scan for ad-hoc transitions and replace hardcoded durations with motion tokens
