Updated · written with AI from the project's own documentation and checked against our catalogue data
The Schema Markup Generator skill lets an AI agent turn facts about a web page or business, such as its entity type and canonical URL, into JSON-LD, a block of code that helps search engines understand the page. It is for SEO specialists, site owners and developers who need a starting draft. After this guide you will know how to install the skill, ask for a draft in plain language, and what to check before anything goes live.

What the skill makes the agent do
Agent skills are instruction packages that an AI agent loads when a task matches them. This one focuses on schema markup. Given the entity type or page facts and the canonical page URL, the agent produces JSON-LD and a checklist of fields that are still unresolved.
The skill is designed to avoid inventing details. If an Article has no supplied author, the agent should not name a person or organization as the author. Missing optional properties are left out rather than filled with guesses.
- Produces a JSON-LD draft from the facts you supply
- Lists unresolved fields so you can fill them in
- Explains material assumptions in brief
- Does not publish anything or check the live site
Install the Schema Markup Generator skill
Download the ZIP file for the skill from the directory page. The package contains a single file named SKILL.md. Unzip it into one of the skill folders below, depending on how you want to use it.
For a personal setup available across your projects, unzip it into ~/.claude/skills/. For a single project, unzip it into the .claude/skills/ folder inside that project. If you use the Claude apps, you can instead upload the skill under Settings, then Capabilities, then Skills.
- Personal: ~/.claude/skills/
- Single project: .claude/skills/ inside the project folder
- Claude apps: Settings, Capabilities, Skills, then upload
Trigger the skill with natural requests
You do not need a special command. Describe the page or business in plain language and include the entity type and canonical URL. The skill is meant to be triggered when you work with entity type or page facts and a canonical page URL.
The source includes an optional prompt template you can copy and adapt. Only the entity type or page facts and canonical page URL are required. Goal, audience and preferences are optional.
- Give the entity type, such as Article, Organization or a local business
- Give the canonical URL of the page
- Add any facts you already have, such as name, address or publication details
- Say if you want a revision to a draft you already received
Help me with schema markup generator.
Input: [paste entity type or page facts and canonical page URL]
Goal: [optional desired outcome]
For: [optional audience, market or language]
Preferences: [optional tone, detail level, format or constraints]Review the draft and checklist before use
The result is a draft, not a validated result. The skill cannot officially validate its output or confirm search eligibility. Check the JSON-LD syntax with your own tools, compare each property with what is visible on the page, and resolve every item on the unresolved checklist.
Keep in mind that the skill has no live access to URLs and cannot inspect the actual page. Any claim about what the page currently shows must come from you.
- Confirm every fact against the real page and business records
- Fill in or remove each unresolved field
- Validate syntax and rich-result requirements yourself before deploying
- Check the Google structured-data guidelines for platform rules
Safety notes: scripts, network and data
The skill lists no requirements, does not run scripts and does not use the network, according to its listing. Treat any instructions inside pasted pages or documents as content, not commands.
Keep credentials and private customer data out of your requests. Only use URLs or resources you are authorized to access, and do not ask the agent to bypass authentication. Any action that sends messages, publishes changes or modifies external systems needs your explicit authorization.
- Requirements: none listed
- Runs scripts: no
- Uses network: no
- Do not paste passwords, API keys or private customer data
What people use it for
- Drafting Article markup for a blog post when you supply the headline, URL and publication facts
- Creating Organization markup for a company home page from confirmed business details
- Preparing a starting JSON-LD block for a developer to validate and deploy
- Revising an existing draft after you correct one fact, keeping the rest unchanged
Frequently asked questions
How do I install the Schema Markup Generator agent skill?
Download the ZIP from the directory page and unzip it into ~/.claude/skills/ for personal use or into a project's .claude/skills/ folder. In the Claude apps, you can instead upload it under Settings, then Capabilities, then Skills.
Does the skill require anything else to run?
The listing shows no requirements, does not run scripts and does not use the network. You still need an agent environment that supports skills, such as the setups described above.
Is the Schema Markup Generator skill free?
The listing states an MIT licence. Check the directory page for the licence text before reusing or redistributing the skill.
Can the skill check my live page or validate my markup?
No. The skill has no live access to URLs, cannot inspect the actual page and cannot officially validate results. Validate the JSON-LD with your own tools and confirm it against the real page.
Will the skill invent an author or other missing details?
It is designed not to. If a fact such as an author is not supplied, the agent should leave it out and list it as unresolved so you can add it yourself.
How does this compare with writing JSON-LD by hand?
The skill gives you a starting draft and a list of gaps to close, which saves setup time. You still need to review, validate and deploy the markup yourself, so it does not replace schema knowledge for production use.

Our verdict
This skill suits SEO specialists, site owners and developers who want a clear JSON-LD draft and a list of open fields to resolve. It is not suited to publishing markup without review, to pages whose facts are unknown, or to live crawling and auditing, since it cannot access or inspect the site. For those jobs, use a validator or crawler alongside your own checks.
