livecodes/import-export

Import and export support for LiveCodes, an online code playground. It can load code from GitHub, GitLab, URLs, web-page elements, and local files, then export projects in formats such as HTML, JSON, or ZIP.

In plain words
What is it for?
Use it to import files, folders, repositories, or gists and export project state or shareable project files.
Why use it?
It avoids copying project files manually when moving code into or out of a LiveCodes project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

livecodes/import-export scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

LiveCodes — Import and Export Code

LiveCodes imports code from external sources and exports projects in multiple formats.

Setup

import { createPlayground, getPlaygroundUrl } from 'livecodes';

// Import from URL
const playground = await createPlayground('#container', {
  import: 'https://github.com/user/repo/blob/main/src/index.js',
});

// Import from URL via query param
// https://livecodes.io/?x=https://github.com/user/repo

// Export to shareable URL
const shareUrl = await playground.getShareUrl();
const shortUrl = await playground.getShareUrl(true);

Core Patterns

Import from GitHub

// GitHub file
createPlayground('#container', {
  import: 'https://github.com/lodash/lodash/blob/master/isObject.js',
});

// GitHub directory
createPlayground('#container', {
  import: 'https://github.com/user/repo/tree/main/src',
});

// GitHub gist
createPlayground('#container', {
  import: 'https://gist.github.com/abc123',
});

// Specify files from multi-file source
createPlayground('#container', {
  import: 'https://github.com/user/repo/tree/main/src',
  params: { files: 'App.tsx,styles.css,index.html' },
});

Import from GitLab

// GitLab snippet
createPlayground('#container', {
  import: 'https://gitlab.com/-/snippets/12345',
});

// GitLab file
createPlayground('#container', {
  import: 'https://gitlab.com/user/repo/-/blob/main/src/index.js',
});

Import from URL

// Raw code URL
createPlayground('#container', {
  import: 'https://example.com/code.js',
});

// URL with language specified
createPlayground('#container', {
  params: {
    x: 'https://example.com/code',
    lang: 'typescript', // Force language
  },
});

// Import from Vue/TypeScript playgrounds
createPlayground('#container', {
  import: 'https://play.vuejs.org/#...',
});

Import from shared project

// Short URL
createPlayground('#container', {
  import: 'id/abc123', // Shared project ID
});

// Compressed config
createPlayground('#container', {
  import: 'code/...', // Compressed base64 config
});

// Via URL
// https://livecodes.io/?x=id/abc123
// https://livecodes.io/?x=code/...

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

livecodes/import-export is a skill published in the GitHub repository live-codes/livecodes (1,488 stars, last pushed 4d ago), licensed MIT. It adds 54 tokens to every session and 1,487 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
