Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: proxy.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned itechmeat/llm-code at 7ae8a00524.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

Bun is an all-in-one JavaScript/TypeScript toolkit that functions as a runtime, package manager, test runner, and bundler. It aims to provide a faster and more streamlined development experience compared to traditional tools like Node.js. Bun enables AI agents to execute TypeScript/JSX code directly without requiring a separate build step, manage project dependencies quickly, and leverage built-in features for tasks such as HTTP server creation, SQLite database interaction, and WebSocket communication.

When to use it

  • Running TypeScript or JSX projects without needing a tsconfig file.
  • Creating fast HTTP servers with native routing capabilities.
  • Working with embedded SQLite databases (without external dependencies).
  • Building WebSocket-based applications for real-time functionality.
  • Interacting with S3-compatible storage services like AWS, R2, or MinIO.

Key capabilities

  • JavaScript/TypeScript runtime environment
  • Package manager (faster than npm)
  • Test runner
  • Bundler
  • Native TypeScript/JSX support (no tsconfig needed)
  • Built-in HTTP server with routing
  • SQLite database integration
  • WebSocket server/client functionality
  • S3-compatible storage access
  • Redis caching and pub-sub capabilities
  • Shell script execution

Example prompts

  • "Run the TypeScript file index.ts using Bun."
  • "Install the 'express' package using Bun."
  • "Create a simple HTTP server with Bun that responds to requests on /api/data."

Tips & gotchas

  • Bun offers built-in support for .env files, eliminating the need for packages like dotenv.
  • When replacing Node.js functionality, use Bun's equivalents (e.g., Bun.serve() instead of http.createServer()).
  • Starting with version 1.3.8+, you can generate bundle analysis reports in Markdown format using bun build ./index.ts --metafile-md.
