Use when building JavaScript/TypeScript applications, running scripts, managing dependencies, bundling code, or testing. Bun is a drop-in replacement for Node.js with integrated package manager, bundler, and test runner.
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 ## Product summary Bun is an all-in-one JavaScript/TypeScript runtime and toolkit. It ships as a single executable (`bun`) and includes a fast runtime (4x faster startup than Node.js), package manager (30x faster installs), bundler, and test runner. Agents use Bun to execute TypeScript/JSX directly without configuration, manage dependencies, bundle applications, and run tests. Key files: `bunfig.toml` (configuration), `package.json` (scripts and dependencies), `bun.lock` (lockfile). Primary CLI commands: `bun run`, `bun install`, `bun build`, `bun test`. See https://bun.com/docs for complete documentation. ## When to use Reach for this skill when: - **Running code**: User asks to execute a TypeScript, JSX, or JavaScript file directly - **Managing dependencies**: Installing, adding, removing, or updating npm packages - **Building/bundling**: Creating optimized bundles for browsers or servers - **Testing**: Writing or running tests with Jest-like syntax - **Scripts**: Running package.json scripts or shell commands - **HTTP servers**: Building web servers with `Bun.serve()` - **File operations**: Reading/writing files with optimized APIs …

How to install
mdr add mweinbach/agent-coworker/bun@sha256:f1537adfc40e5395The 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.
