What bun-development does

bun-development is for tasks that use the Bun runtime. It covers starting JavaScript or TypeScript projects, moving an existing project from Node.js, working with Bun's built-in bundler and test runner, and investigating Bun-specific issues. It also addresses development-speed work inside this runtime.

Before execution, the skill requires reading references/detailed-guide.md, which contains the procedure, prerequisites, and validation requirements. Its scope is limited to tasks that clearly match Bun development, and its output does not replace environment validation, testing, or expert review. The risk: critical label is a reason to check changes separately before applying them.

What it helps with

  • start a new Bun project
  • move a JavaScript project from Node.js to Bun
  • use Bun's built-in bundler
  • run tests with Bun's test runner
  • troubleshoot a Bun-specific issue

Example prompts for the agent

  • Use the `bun-development` skill to create a TypeScript project with Bun.
  • Apply `bun-development` to plan a migration from Node.js to Bun.
  • Use `bun-development` to investigate a failure in Bun's tests or bundler.
