Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install json-schema-design

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 writes JSON Schemas for your APIs, configuration files and data exchanges, covering types, numeric constraints, $ref, allOf, oneOf and if/then/else. You get a documented schema, ready to validate your data.
