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 passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • 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 undeclared network calls: passed

    Makes no network calls.

    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.

  • 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 oven-sh/bun at ad60a9b7bb.

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

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to automatically generate comprehensive test suites specifically tailored for bundler configurations. It ensures that build pipelines remain robust by validating changes against various bundling scenarios without manual intervention.

When to use it

  • Automating regression testing when modifying Webpack, Vite, or Rollup configuration files.
  • Validating that new dependencies do not break the existing module resolution strategy.
  • Ensuring consistent output across different environments during continuous integration pipelines.
  • Rapidly prototyping bundler setups while maintaining immediate feedback on build failures.

Key capabilities

  • Generates executable test cases for complex bundler logic.
  • Covers edge cases in dependency injection and tree-shaking behaviors.
  • Adapts to multiple popular bundlers including Webpack, Vite, and esbuild.
  • Produces runnable scripts that can be integrated directly into CI/CD workflows.

Example prompts

  • "Create a test suite for my Webpack configuration to verify code splitting works correctly."
  • "Generate tests that check if my Vite setup handles dynamic imports without errors."
  • "Write automated checks to ensure my bundler output meets specific performance benchmarks."

Tips & gotchas

Ensure your project has an existing bundler configuration before running this skill, as it relies on analyzing current settings. While effective for standard setups, highly custom or experimental bundler plugins may require manual review of generated tests.
