Shimmering Text — primitive for text reveals (react)

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

A glint of light running letter by letter across grey text, each letter brightening as it passes

Prompt that renders it frame-exact

Use Animate UI's Shimmering Text (https://animate-ui.com/docs/primitives/animate-ui/shimmering-text, MIT + Commons Clause) for an AI "thinking…" line or a subtle caption. npm install @animate-ui/react motion and render <ShimmeringText text="…" />. Each letter pulses from color to shimmeringColor and back over duration, staggered by duration / letters, on Motion's clock. To render it frame-exact, compute each letter's colour mix from the frame: phase = (frame / fps − i × duration / n) mod (duration + 0.05 × n), mapped through an ease-in-out (Remotion: interpolateColors; HyperFrames: a paused GSAP stagger on the letter spans). Set color and shimmeringColor; wave adds a small lift and turn as the glint passes.
