seo-schema
Detect, validate, and generate Schema.org structured data. JSON-LD format preferred. Use when user says "schema", "structured data", "rich results", "JSON-LD", or "markup".
npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill seo-schema --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Schema Markup Analysis & Generation ## Detection 1. Scan page source for JSON-LD `<script type="application/ld+json">` 2. Check for Microdata (`itemscope`, `itemprop`) 3. Check for RDFa (`typeof`, `property`) 4. Always recommend JSON-LD as primary format (Google's stated preference) ## Validation - Check required properties per schema type - Validate against Google's supported rich result types - Test for common errors: - Missing @context - Invalid @type - Wrong data types - Placeholder text - Relative URLs (should be absolute) - Invalid date formats - Flag deprecated types (see below) ## Schema Type Status (as of Feb 2026) Read `references/schema-types.md` for the full list. Key rules: ### ACTIVE (recommend freely): Organization, LocalBusiness, SoftwareApplication, WebApplication, Product (with Certification markup as of April 2025), ProductGroup, Offer, Service, Article, BlogPosting, NewsArticle, Review, AggregateRating, BreadcrumbList, WebSite, WebPage, Person, ProfilePage, ContactPage, VideoObject, ImageObject, Event, JobPosting, Course, DiscussionForumPosting ### VIDEO & SPECIALIZED (recommend freely): BroadcastEvent, Clip, SeekToAction, SoftwareSourceCode See `schema/templa

What does the seo-schema skill do?
Detect, validate, and generate Schema.org structured data. JSON-LD format preferred. Use when user says "schema", "structured data", "rich results", "JSON-LD", or "markup".
How do I install it?
Run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill seo-schema --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Infrasity-Labs/dev-gtm-claude-skills, a repository with 97 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
