# Before → After Metric — effect skill for numbers & charts > **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q="` 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. The old number shows, gets crossed or rolls, and the new better number takes its place. - **Type:** [Effect](https://varg.ai/how-to/effects.md) · [Numbers & charts](https://varg.ai/how-to/browse/skills/numbers.md) - **Slug:** `before-after-metric` - **Status:** live - **Publisher:** Kapish Dima · remocn (community) - **License:** MIT - **Source:** https://remocn.dev/r/value-swap.json - **Works in:** Claude Code, Claude.ai, Codex, Cursor, OpenClaw, Gemini CLI, Any MCP client, varg Studio - **Requires:** HyperFrames (npx hyperframes), Remotion, CapCut (by hand) - **Cost:** Free — the take renders locally; generated footage, if any, bills by the model ## What it does Built on [Value Swap](https://remocn.dev/r/value-swap.json) by Kapish Dima (remocn), MIT. The write-up and recipes below are varg's. "12 months" in grey slides up and out; "2 weeks" rolls in bold accent; an arrow or delta chip ("−83%") pops beside it. **When:** Outcome claims: time saved, cost cut, conversion lifted. **Watch out:** Do not show the delta before the viewer has read the old value; give it ~1 s. **Timing:** Old hold 0.8–1.2 s, swap 0.4–0.6 s, delta chip pop 0.2 s, hold 1.5 s. **Also called:** value swap, metric change, from-to number ### In HyperFrames ```bash npx hyperframes add slot-machine-roll ``` Or `strikethrough-replace` when the old value should be crossed out. ### In Remotion ```tsx // npx shadcn@latest add @remocn/value-swap ``` ### In CapCut Two Text layers; old one Animation Out "Slide up", new one In "Slide up" at the same frame; add a delta chip sticker. ### Ready-made components - [Value Swap](https://skills.varg.ai/component/remocn.value-swap/) (remocn): npx shadcn@latest add @remocn/value-swap - [Slot Machine Roll](https://skills.varg.ai/component/hf.slot-machine-roll/) (hyperframes): npx hyperframes add slot-machine-roll - [Strikethrough Replace](https://skills.varg.ai/component/hf.strikethrough-replace/) (hyperframes): npx hyperframes add strikethrough-replace ### Where this comes from - [Bohdan Motion: Secureframe launch video, one pain per scene](https://x.com/bohdanmotion/status/2069369111231049803) ## Use when - Outcome claims: time saved, cost cut, conversion lifted. ## Not for - Do not show the delta before the viewer has read the old value; give it ~1 s. ## Install - Claude Code: `claude plugin marketplace add vargHQ/skills && claude plugin install varg@varg` - Codex: `npx skills add vargHQ/skills --skill varg-video-edit-library -a codex -y` - Cursor: `npx skills add vargHQ/skills --skill varg-video-edit-library -a cursor -y` ## Example output https://s3.varg.ai/how-to/previews/4c97906d2cb8/take-before-after-metric.mp4 — The Slot Machine Roll component used as its header comment describes, with demo copy (credit: Rendered by varg · HyperFrames Slot Machine Roll, https://hyperframes.heygen.com/catalog/components/slot-machine-roll) ## More numbers & charts skills - [Big Stat Count-Up](https://varg.ai/how-to/skills/big-stat-count-up.md): One huge number counts from zero to its value and lands, with a short label under it. - [Odometer Digit Roll](https://varg.ai/how-to/skills/odometer-digit-roll.md): Each digit rolls on its own wheel to the target, places settling right to left like an odometer. - [Bars Grow with Value Labels](https://varg.ai/how-to/skills/bars-grow-with-labels.md): Bars rise from the baseline in a staggered cascade with values riding their tops. - [Line Draws with Riding Label](https://varg.ai/how-to/skills/line-draws-riding-label.md): A line draws itself left to right while the current value rides the pen tip, ending on a dot and big label. - [Ranked Bar Race](https://varg.ai/how-to/skills/ranked-bar-race.md): Ranked bars grow and overtake each other over time while the axis rescales and a year/date ticks. - [Progress Ring Fills](https://varg.ai/how-to/skills/progress-ring-fills.md): A thin ring draws on to a percentage while the number in its center counts up in sync. ## Run the generation on varg varg is one API key for the models these skills drive — Seedance 2.5, Kling 4, Veo 3.1, Wan 3, Nano Banana 2.1, GPT Image 2.5, ElevenLabs v4 and 200+ more — billed in credits, with a cost estimate before anything runs. - Claude Code: `claude plugin marketplace add vargHQ/skills && claude plugin install varg@varg` (skill + hosted MCP) - Codex, Cursor, Gemini CLI, OpenClaw: `npx skills add vargHQ/skills --skill varg-ai -a -y` - Grok and any agent that reads SKILL.md: `npx skills add vargHQ/skills --skill varg-ai`, or point it at the skill's SKILL.md - Claude.ai, ChatGPT, any MCP client: connect `https://mcp.varg.ai/mcp` - API key: https://varg.ai/dashboard/api · Model specs: https://varg.ai/models/llms.txt
