# One-Line Install Card — effect skill for code & terminal

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

A single install command types into a small terminal card, prints a success check, and holds.

## What it does

Built on [Terminal](https://github.com/magicuidesign/magicui/blob/main/apps/www/registry/magicui/terminal.tsx) by magic-ui, MIT. The write-up and recipes below are varg's.

Compact terminal (or pill) with `npx … add` typing, a green ✓ line, and a copy icon; centered with lots of air.

**When:** End of a developer video, right before or as the CTA.

**Watch out:** Do not show a multi-step install; one copyable line or link to docs.

**Timing:** Typing 60–80 ms/char, ✓ line after 0.4 s, hold 2–3 s.

**Also called:** install command, npx line, get started command

### In FFmpeg

```bash
-vf "drawtext=fontfile=JetBrainsMono.ttf:text='$ npx skills add varg-ai':x=(w-tw)/2:y=h/2:fontsize=48:fontcolor=white:box=1:boxcolor=0x111111@0.9:boxborderw=28"
```

### In HyperFrames

```bash
npx hyperframes add code-snippet-apple-terminal-pro
```
Set the command text in the block variables; keep it on one line.

### In Remotion

```tsx
// npx shadcn@latest add @magicui/terminal  (drive typing from frame, not timers)
const n = Math.floor(interpolate(frame,[0,cmd.length*2],[0,cmd.length],{extrapolateRight:'clamp'}));
```

### In CapCut

Text → monospace font on a dark rounded shape; Animation In "Typewriter" 1–1.5 s; add a ✓ text line 0.4 s later.
