Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install seo-codebase-audit

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 inspects the site, finds the indexable pages, then directly fixes titles, descriptions, canonicals, sitemap, robots.txt and JSON-LD. It also builds 1200×630 social images and ends with a summary of changes and the decisions still open.
