code-upgrade

Safely upgrade dependencies or migrate framework versions.

Process

• If code changes are involved: run jj diff -s first to see changed files; then use jj diff -- path to restrict to specific files/directories

Step 1 - Identify Upgrade Type

Ask the user to clarify what they want to upgrade:

• Single dependency: Upgrade one package (e.g., react 18 -> 19)
• All dependencies: Update all packages to latest compatible versions
• Framework migration: Major version upgrade with breaking changes (e.g., Next.js 13 -> 15)
• Language version: Update runtime version (e.g., Python 3.11 -> 3.12)

Step 2 - Analyze Current State
