# True Focus — 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.

Corner brackets jump from word to word, sharpening the framed word while the rest stay blurred

## Prompt that renders it frame-exact

Use True Focus from React Bits (https://reactbits.dev/text-animations/true-focus, MIT + Commons Clause: OK in a video). Install with `npx shadcn@latest add @react-bits/TrueFocus-JS-CSS` and use it on a short claim where each word should land on a beat ('Fast. Private. Yours.'). Set sentence, blurAmount, borderColor and glowColor from the brand, focusStyle, animationDuration and pauseBetweenAnimations. It moves the focus on setInterval with Motion. Compute the focused index as floor(t / (animationDuration + pauseBetweenAnimations)) % words, with t = frame / fps, ease the bracket position from the time inside that step, and keep manualMode off.
