This handles the tedious work of upgrading assistant-ui and AI SDK packages when breaking changes are involved. It detects your current versions from npm, figures out which migrations you need (like the AI SDK v4/v5 to v6 jump or assistant-ui's runtime API changes), then walks you through them in the right order. The skill includes reference docs for specific version migrations and a troubleshooting section for peer dependency conflicts. Honestly most useful when you've been putting off an upgrade because you don't want to dig through changelogs to figure out what broke.
