Dependency Upgrade

Master major dependency version upgrades, compatibility analysis, staged upgrade strategies, and comprehensive testing approaches.

Do not use this skill when

• •The task is unrelated to dependency upgrade
• •You need a different domain or tool outside this scope

Instructions

• •Clarify goals, constraints, and required inputs.
• •Apply relevant best practices and validate outcomes.
• •Provide actionable steps and verification.
• •If detailed examples are required, open resources/implementation-playbook.md.

Use this skill when

• •Upgrading major framework versions
• •Updating security-vulnerable dependencies
• •Modernizing legacy dependencies
• •Resolving dependency conflicts
• •Planning incremental upgrade paths
• •Testing compatibility matrices
• •Automating dependency updates

Semantic Versioning Review

MAJOR.MINOR.PATCH (e.g., 2.3.1)

MAJOR: Breaking changes
MINOR: New features, backward compatible
PATCH: Bug fixes, backward compatible

^2.3.1 = >=2.3.1 <3.0.0 (minor updates)
~2.3.1 = >=2.3.1 <2.4.0 (patch updates)
2.3.1 = exact version
