Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install json-ld-validation

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 reads the markup you supply (JSON-LD, Microdata or RDFa), checks it against the official reference and lists the errors to fix. The deliverable follows the format the skill defines.
