What problem does it solve? Upgrading @dextinity/* packages across a major version involves breaking changes across React, Next.js, and MUI X, plus codemods, config updates, and runtime regressions that lint and tsc cannot catch. This Skill orchestrates the entire migration so no guide step, site, or verification pass is missed. ## Core Features & Use Cases - Guide-driven migration: Locates the official Dextinity migration guide for the target major, resolves the newest stable release within that major, and works through every section with per-section commits. - Project shape detection: Discovers whether the project has zero, one, or multiple sites and whether a page tree exists, then applies site-specific steps once per site. - Independent audit and smoke test: Verifies the migration with a fresh subagent cross-referencing commits against the guide, then runs a Playwright-driven browser smoke test of admin routes, page-tree CRUD, and site URLs. - Use Case: You need to upgrade a Dextinity project from v5 to v6 with two sites. The Skill downloads the official guide, bumps all @dextinity/* packages to the latest v6 release, applies each section per site, commits incrementally, and produces a test-report.md of browser-verified findings. ## Quick Start Migrate this project from Dextinity v5 to v6 following the official migration guide.
