Why does it check for native modules?

Certain Node.js native modules may have compatibility issues or require specific configurations to run under Bun; identifying these early prevents runtime failures after migration.

How are the audit findings prioritized?

Findings are ranked from P0 (immediate blockers that stop migration) to P3 (nice-to-have optimization opportunities), helping you focus on the most critical tasks first.

What does the check-bun skill actually do?

It performs a read-only audit of your project to see if it is compatible with the Bun runtime and identifies any issues that would prevent a successful migration.

Can it detect platform-specific blockers like Expo?

Yes, it specifically checks for deployment targets like Expo/EAS where the Bun runtime is currently not supported, marking them as P0 blockers.

Does this skill automatically change my project files?

No, check-bun is a primitive that only reports findings. To apply specific fixes or perform the migration, you should use the related /fix-bun or /bun skills.

デプロイメントとDevOps

Analyzes projects to determine Bun runtime compatibility and identifies migration opportunities or blockers.

The check-bun skill provides a comprehensive audit for developers looking to migrate from Node.js, npm, yarn, or pnpm to the Bun runtime. It systematically scans your project for lockfile conflicts, deployment platform limitations (such as Expo or Vercel), incompatible native modules, and CI/CD configurations. By generating a structured, prioritized report of blockers and optimization opportunities, it allows you to make an informed decision on whether to proceed with a full migration, adopt a hybrid setup, or maintain your current environment.
