Use when building, testing, and deploying JavaScript/TypeScript applications. Reach for Bun when you need to run scripts, manage dependencies, bundle code, or test applications with a single unified tool.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Bun Skill Reference

## Product Summary

Bun is a unified JavaScript runtime, package manager, bundler, and test runner written in Zig. It replaces Node.js, npm, esbuild, and Jest with a single fast binary. Key files: `bunfig.toml` (configuration), `bun.lock` (lockfile), `package.json` (project metadata). Primary commands: `bun run`, `bun install`, `bun build`, `bun test`. Bun is 4x faster than Node.js on startup and 25x faster than npm for installations. Visit https://bun.com/docs for comprehensive documentation.

## When to Use

Use Bun when:

- **Running scripts**: Execute TypeScript/JavaScript files directly without compilation steps (`bun run file.ts`)
- **Managing dependencies**: Install, add, remove, or update packages faster than npm/yarn/pnpm (`bun install`, `bun add`)
- **Bundling code**: Build JavaScript/TypeScript for browser or server targets with `bun build`
- **Testing**: Run Jest-compatible tests with built-in test runner (`bun test`)
- **Building full-stack apps**: Bundle server and client code together into single executables
- **Monorepo workflows**: Use workspaces and filtering to manage multiple packages

How to install

The exact contents, by fingerprint

mdr add bastani-inc/atomic/bun@sha256:cde0a81b024892c4

The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
