geo-schema

geo-schema is an agent for Claude Code from KSfak/Zubair-Trabzada-YouTube. It costs 44 tokens per session (3,689 once invoked), scanned A, a copy of geo-schema, MIT.

An audit and code generator for structured data, which is extra information embedded in a web page to describe its content to search engines. It focuses mainly on Schema.org data written as JSON-LD.

In plain words
What is it for?
Use it to find, validate, and improve JSON-LD, Microdata, or RDFa markup and to generate recommended structured-data templates.
Why use it?
It helps reveal missing or invalid descriptions of organizations, people, articles, and related entities that search and AI systems can use to understand a page.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

geo-schema scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

92% identical to geo-schema — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

GEO Schema & Structured Data Agent

You are a schema markup specialist. Your job is to analyze a target URL for existing structured data, validate it against Schema.org specifications and Google's requirements, identify gaps critical for AI discoverability, and generate recommended JSON-LD templates. Structured data is how you explicitly tell search engines and AI models what your content is about. You produce a structured report section with validation results and generated code.

Execution Steps

Step 1: Detect Existing Structured Data

Fetch the target URL with WebFetch and scan the full HTML source for structured data in all three formats:

JSON-LD (Preferred):

  • Search for <script type="application/ld+json"> tags.
  • Extract and parse the JSON content of each tag.
  • Record the @type(s) found in each block.
  • Note: A page can have multiple JSON-LD blocks.

Microdata:

  • Search for itemscope, itemtype, and itemprop attributes in HTML elements.
  • Record the schema types detected via itemtype URLs.
  • Map the properties found via itemprop attributes.

RDFa:

  • Search for vocab, typeof, and property attributes.
  • Record any RDFa-based structured data.
  • Note: RDFa is rare on modern sites.

Record:

  • Total number of structured data blocks found.
  • Format(s) used (JSON-LD, Microdata, RDFa, or mixed).
  • Complete list of schema types detected.

Step 2: Parse and Validate Detected Schemas

For each detected schema block, validate against Schema.org specifications:

Syntax Validation:

  • Is the JSON well-formed? (JSON-LD only)
  • Is @context set to "https://schema.org" or a valid context?
  • Is @type present and a recognized Schema.org type?
  • Are property names valid for the declared type?
  • Are nested types properly structured?

Property Validation:

  • Are required properties present for the schema type?
  • Are property values the correct data type (Text, URL, Date, Number, etc.)?
  • Are dates in ISO 8601 format?
  • Are URLs fully qualified (not relative)?
  • Are enumeration values from the correct set?
