When the user wants to add, fix, or validate schema markup (JSON-LD), or asks which type fits a page or whether some markup is allowed: product, review, recipe, FAQ, rich result eligibility (FAQ no longer earns Google rich results), Search Console errors. For broader SEO, see seo-audit. For AI search, see ai-seo.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'schema' ] || [ -L ~/.agents/skills/'schema' ]; then echo 'A skill folder named schema already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/coreyhaines31/marketingskills' "$d" && git -C "$d" checkout --quiet '1f837447b20bb6f0e72d87b80ece1c221c362c7d' -- 'skills/schema' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/schema' ~/.agents/skills/'schema' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'schema' ~/.claude/skills/'schema' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
