## What it does

The skill picks the right schema type from the page content and returns ready JSON-LD. It ships templates for Article, BlogPosting, NewsArticle, Product, FAQPage and HowTo, each with Google's rich result requirements attached.

Article needs `headline` under 110 characters, `image` in three aspect ratios (16:9, 4:3, 1:1, each wider than 696px), `datePublished` in ISO 8601 and an author name. Product needs at least one of `offers`, `review` or `aggregateRating`, and price plus currency once `offers` is there. Google only shows FAQPage markup when the questions are visible on the page rather than hidden behind tabs, so check your markup before pasting the code in.

Install runs through `npx skills add` for Claude, Codex, Cursor, Gemini CLI and OpenCode. GitHub Copilot uses `gh skill install` instead. The skill file lands at a path like `.cursor/skills/schema-markup/SKILL.md` or `~/.claude/skills/schema-markup/SKILL.md`, so you can edit the templates for your own project.
