# 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
```
