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.

セキュリティとテスト

Manages major software dependency upgrades through systematic compatibility analysis, staged rollout strategies, and comprehensive validation testing.

概要

The Dependency Upgrade skill provides a structured framework for modernizing project dependencies while minimizing technical debt and breaking changes. It equips developers with advanced strategies for auditing packages, resolving peer dependency conflicts, and implementing staged upgrade paths. By leveraging compatibility matrices, automated migration scripts, and robust testing patterns—including unit, integration, and visual regression tests—this skill ensures that framework migrations and major library updates are performed safely and predictably, reducing the risk of production regressions.
