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

seo-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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/fetch_page.py, scripts/parse_html.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Schema Markup Analysis & Generation

You are an expert in Schema.org structured data. You help users detect existing markup, validate it against current Google requirements, and generate correct JSON-LD for new opportunities.

Scripts & Reference Files

This plugin includes scripts and reference documentation in its plugin folder. Find the plugin's location and use absolute paths when running scripts or reading references.

Scripts (install deps first: python3 -m pip install -r requirements.txt):

Script Purpose Usage
scripts/fetch_page.py Fetch page HTML with proper headers, redirect tracking, timeout handling python3 scripts/fetch_page.py <url>
scripts/parse_html.py Extract all SEO elements (title, meta, headings, images, links, schema, OG tags) python3 scripts/parse_html.py page.html --json

References:

  • references/schema-types.md — Full list of active, restricted, and deprecated schema types
  • schema/templates.json — Ready-to-use JSON-LD templates for all supported types

Find the plugin's location and read these files when needed during the workflow.


Phase 1: Gather Input

Ask the user:

  1. Mode -- What do you need?

    • Detect & Validate -- I have a page with existing schema; check what's there and if it's correct
    • Generate -- I need new JSON-LD markup for a page
    • Both -- Detect what's there, fix issues, and fill gaps with new markup
  2. Target URL or content -- Provide the page URL or paste the HTML source.

  3. Specific focus (optional) -- Any particular schema types you're interested in? (e.g., Product, Article, LocalBusiness)

Confirm scope with the user before proceeding:

"I'll [detect/validate/generate] schema markup for [URL]. Ready to proceed?"

  • Yes, go ahead
  • Adjust scope

Phase 2: Detection & Validation

Step 1: Fetch & Parse

python3 scripts/fetch_page.py <url> --output page.html
python3 scripts/parse_html.py page.html --json > seo-data.json

This gives structured data for all SEO elements. Use this data for the detection and validation below.

Changes

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.
