dependency-upgrade

Quick Review

This is a high-quality, comprehensive skill for managing dependency upgrades. The description clearly conveys when to use it (major upgrades, security updates, breaking changes). The skill provides excellent task knowledge with concrete commands, code examples, and multi-phase strategies covering analysis, staged rollouts, testing, automation, and rollback. Structure is good with logical sections and a helpful checklist, though some referenced files (semver.md, compatibility-matrix.md, etc.) would ideally contain the detailed content to keep SKILL.md concise. Novelty is moderate-to-good: while dependency upgrades are common, the comprehensive approach with compatibility matrices, codemods, visual regression testing, and staged strategies goes beyond what a CLI agent could easily orchestrate in a single session, providing meaningful token savings and workflow orchestration.
