Bun development/runtime: adoption, Node migration, lockfiles/package-manager drift, bunfig, test, build, and command policy.
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 Dev The single Bun skill: self-contained knowledge (below) + an opinionated rule set (`rules/`) + an optional native audit/fix engine (`codex-dev bun`). It works with zero tooling; the Power Tools section adds automation when `codex-dev` is installed. ## Product summary Bun is an all-in-one JavaScript/TypeScript toolkit: a fast runtime (drop-in Node.js replacement on JavaScriptCore), package manager, bundler, and test runner, all shipped as one `bun` binary. Key files: `bunfig.toml` (config), `bun.lock` (text lockfile, default since Bun 1.2), `package.json`. Primary commands: `bun run`, `bun install` / `bun ci`, `bun build`, `bun test`. Full docs: <https://bun.com/docs> (agent index: <https://bun.com/docs/llms.txt>). ## When to use - **Runtime**: execute `.ts/.tsx/.jsx/.js` directly (`bun run <file>` or `bun <file>`). - **Package manager**: `bun install` / `bun add` / `bun ci`; lockfile + workspace mgmt. - **Bundler**: `bun build` for browsers/servers; single-file executables (`--compile`). - **Test runner**: Jest-compatible `bun test` with scale flags for CI. - **Servers / IO**: `Bun.serve()`, `Bun.file()`, `Bun.write()`, `bun:sqlite`, `Bun.$`. …

How to install
mdr add bjornmelin/dev-skills/bun-dev@sha256:be8c28b9a7f138e4The line at the top of this page pins the label v2.0, 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.
