Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install zod-4-schema-validation-2

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent replaces old Zod 3 syntax with Zod 4 forms (z.email(), z.uuid(), the { error } message option), then builds the schemas, transformations and refinements. You get validation code compatible with Zod 4, including React Hook Form integration.
