# Community Post as Proof — effect skill for quotes & reviews

> **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 real community post or comment card pops over the footage with its upvotes counting up.

## What it does

Built on [Reddit Post Card](https://github.com/heygen-com/hyperframes/tree/main/registry/blocks/reddit-post) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Reddit-style or YouTube-comment-style card, platform-faithful; the text types on, then the vote count rises.

**When:** Developer and consumer products where community chatter is more believable than a logo.

**Watch out:** Do not fake platform UI for posts that never existed; quote real ones and blur usernames if needed.

**Timing:** Card pop 0.3 s, typing 30–40 ms/char, count-up 0.8 s.

**Also called:** reddit post, forum thread proof, comment card

### In HyperFrames

```bash
npx hyperframes add reddit-post
```
Or `npx hyperframes add yt-comment-card` for comment-style proof over footage.

### In Remotion

```tsx
const chars = Math.floor(interpolate(frame,[6,6+text.length*1.1],[0,text.length],{extrapolateLeft:'clamp',extrapolateRight:'clamp'}));
<p>{text.slice(0,chars)}</p>
```

### In CapCut

Add the screenshot as Overlay, Animation In "Pop up"; place it in the upper third so captions stay clear.
