Does this skill automatically update my code?

It provides specific instructions, code snippets, and search commands to help you identify and fix issues manually or with Claude's assistance.

Why does the Tailwind 4 upgrade tool fail for me?

One common reason identified by this skill is uncommitted Git changes; the @tailwindcss/upgrade tool requires a clean working directory to run successfully.

Which versions of Zod and Vitest are covered?

The skill specifically addresses the transition from Zod 3 to 4 and Vitest 2 to 4, covering the most common edge cases found in real-world projects.

How does this differ from official migration guides?

Official guides cover documented API changes; this skill focuses on non-obvious runtime 'gotchas' and silent failures that official documentation often misses.

Identifies and resolves non-obvious runtime errors encountered during major library upgrades for Zod, Vitest, and Tailwind CSS.

2026 Migration Patterns provides critical technical guidance for upgrading core development libraries to their latest standards, specifically focusing on Zod 4, Vitest 4, and Tailwind CSS 4. Unlike official migration guides that cover documented API changes, this skill targets 'silent' runtime failures, such as Zod enum key requirements and Vitest arrow function constructor limitations. It provides developers with ready-to-use Ripgrep commands to scan repositories for affected patterns and offers copy-pasteable boilerplate for robust test environment setups, ensuring a smooth transition across the modern web stack.
