Code Left, Live UI Right — effect skill for code & terminal

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 how-to page 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 how-to page.

Code types on the left and the UI on the right snaps to match after each change.

What it does

Built on Live Code Compilation by Kapish Dima (remocn), MIT. The write-up and recipes below are varg's.

Two panes: editor and preview. Each typed edit triggers a quick flash/update on the preview side.

When: Frameworks, UI libraries, design-to-code and AI coding tools.

Watch out: Do not let the preview lag; the update should land within 0.2 s of the edit finishing.

Timing: Per edit: typing 0.8–1.5 s, preview update 0.2–0.3 s.

Also called: live preview, split code and result, HMR demo

In HyperFrames

npx hyperframes add code-typing

Two clips side by side; fire a 0.25 s tl.fromTo(preview,{opacity:0.4},{opacity:1}) and swap the preview image at each edit's end time.

In Remotion

// npx shadcn@latest add @remocn/live-code-compilation
// or @remocn/chat-to-preview-layout for chat on the left

In CapCut

Split screen: two clips side by side (Basic → Position); cut the preview clip at each edit point.

Ready-made components

• Live Code Compilation (remocn): npx shadcn@latest add @remocn/live-code-compilation
• Chat to Preview Layout (remocn): npx shadcn@latest add @remocn/chat-to-preview-layout
• Code Typing (hyperframes): npx hyperframes add code-typing

Where this comes from

• Cursor 3 Design Mode and its launch video
• Bohdan Motion: breakdown of the Grok Build Mode launch video

Use when

• Frameworks, UI libraries, design-to-code and AI coding tools.

Not for

• Do not let the preview lag; the update should land within 0.2 s of the edit finishing.

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

More code & terminal skills

• Editor Types the Code: Syntax-highlighted code types into an editor window with a caret riding the frontier.
• Red/Green Diff Collapse: Removed lines flash red and collapse away while added lines expand in green.
• Spotlight One Line of Code: A highlight band sweeps onto the one line that matters while the rest of the file dims.
• Code Morphs Between Versions: One snippet transforms into the next: shared tokens glide to new positions, removed ones fade, new ones fade in.
• Terminal Session Run: A terminal types a command, then streams real-looking log output with green checks.
• One-Line Install Card: A single install command types into a small terminal card, prints a success check, and holds.

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.
