Does it support both npm and yarn?

Absolutely. It provides standardized commands and best practices for both npm and yarn, including lockfile management and peer dependency resolution.

Can I use this for framework-level migrations like React 17 to 18?

Yes, it specifically includes strategies for major framework upgrades, including staged rollout plans and compatibility matrices to ensure all ecosystem plugins are ready.

How does this skill handle breaking changes during an upgrade?

The skill identifies breaking changes through changelog analysis and provides automated remediation patterns using codemods and custom migration scripts to update deprecated APIs.

What kind of testing does it recommend for upgrades?

It advocates for a comprehensive suite including unit tests for logic, integration tests for component interaction, visual regression for UI consistency, and E2E tests for critical user flows.

How do I prevent future dependency rot?

The skill includes configurations for automated tools like Renovate and Dependabot to help you stay current with minor and patch updates automatically.
