🧑‍💻 Hey Claude, can do that same refactor on these 62 files, so I can focus on other things?

🤖 Of course!



🤖 Given the complexity, let me create a script…
🤖 Wait, that's strange. Let me check more carefully…
🤖 I see, they are similar. Let me update in batch…
🤖 I see the issue now…
🤖 Wait…

If you are still on Zod 3 and plan to migrate to Zod 4, I've created a codemod to help you do so: www.npmjs.com/package/zod-...

Steps:
1. Upgrade your dependency to Zod 4
2. Run `npx zod-v3-to-v4`

That should cover most scenarios

Let me know if you have any trouble with it 👐
