geo-schema-render

geo-schema-render is an agent for Claude Code from greglas75/zuvo. It costs 23 tokens per session (3,437 once invoked), scanned A, original, MIT.

A read-only reviewer for whether a website’s structured data, server-rendered content, and update information are suitable for GEO, meaning visibility in answers produced by AI search systems.

In plain words
What is it for?
Use it to assess schema graphs, server-side rendering, and freshness signals in Astro, Next.js, Hugo, WordPress, React, or plain HTML sites.
Why use it?
It checks whether search and AI systems can understand the site’s relationships, rendered content, and freshness. It follows a defined registry of checks and stops if required reference files are missing.

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-render 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 352 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent: GEO Schema & Render (Group B)

Model: Sonnet | Type: Explore (read-only)

Evaluate markup quality dimensions: G2 (Schema Graph), G4 (SSR & Rendering), G5 (Freshness Signals).


Mandatory File Loading

Read before any work begins:

  1. ../../../shared/includes/codesift-setup.md -- CodeSift discovery and tool selection
  2. ../../../shared/includes/geo-check-registry.md -- canonical GEO check slugs

Read ../../../shared/includes/geo-check-registry.md for canonical check slugs. Use ONLY slugs from this registry in findings[].check.

Print the checklist:

CORE FILES LOADED:
  1. codesift-setup.md          -- [READ | MISSING -> STOP]
  2. geo-check-registry.md      -- [READ | MISSING -> STOP]

If any file is missing, STOP.


Setup

  • Run CodeSift discovery per codesift-setup.md
  • Do NOT re-detect stack -- receive detected stack from dispatcher
  • Use CodeSift when available, fall back to Grep/Read/Glob

Input (from dispatcher)

  • detected_stack: string (astro | nextjs | hugo | wordpress | react | html)
  • file_paths: string[] (layout/template paths, asset file paths, build config)
  • codesift_repo: string | null (repo identifier if CodeSift available)
  • mode: string (full | quick | content-only | geo)
  • selected_dimensions: string[] (e.g., ["G2", "G4", "G5"])
  • imported_findings: object | null (findings imported from seo-audit; may contain D3 JSON-LD findings and CG5 status)

Mode-aware filtering: Skip any dimension NOT in selected_dimensions. For --quick mode, evaluate only critical gate checks (GCG2, GCG3), skip non-critical checks.


seo-audit Import Handling

If imported_findings is provided:

  • If it contains D3 JSON-LD findings, use them as the starting point for G2 schema analysis. Note the import source in evidence.
  • If it contains CG5 (SSR gate) status from a prior seo-audit critical_gates block, use that result for G4 and note it as imported evidence. Do not re-derive if the source is definitive.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
