Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install html-markdown-to-portable-text

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 picks the right conversion: markdownToPortableText for Markdown, htmlToBlocks for HTML from a legacy CMS, or manual construction from an API or database. It relies on the Portable Text specification and custom deserializers. You get Portable Text documents ready to import.
