Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.02101 |
| Opus 5 | $0.00013 | $0.01051 |
| Sonnet 5 | $0.00005 | $0.00420 |
| Haiku 4.5 | $0.00003 | $0.00210 |
Grade A, and why
SEO Metadata Generator 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 10d 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.

SEO Metadata Generator
What this skill does
This skill generates a complete set of SEO metadata for any web page — title tag, meta description, Open Graph tags, Twitter Card tags, and JSON-LD structured data — all in a single ready-to-paste HTML snippet. It analyzes the page's content and purpose, chooses the right structured data schema (Article, Product, WebPage, FAQPage, etc.), and optimizes every field for both search engines and social sharing.
Use this when building a new page, auditing existing metadata, or ensuring consistent SEO across a site.
How to use
Claude Code / Cline
Copy this file to .agents/skills/seo-metadata-generator/SKILL.md in your project root.
Then describe the page or share its content and ask:
- "Use the SEO Metadata Generator skill to generate metadata for our pricing page."
- "Generate SEO tags for this blog post using the SEO Metadata Generator skill."
Provide: the page's main content or purpose, the primary keyword, the page URL, the site name, and an available OG image URL (or a placeholder if none exists yet).
Cursor
Add the "Prompt / Instructions" section to your .cursorrules file. Open the page template or content file and ask Cursor to generate the metadata.
Codex
Describe the page content, primary keyword, URL, site name, and page type. Include the instructions below.
The Prompt / Instructions for the Agent
When asked to generate SEO metadata, follow these steps:
-
Understand the page. Extract or ask for:
- Page type: article/blog post, product page, landing page, homepage, tool/app page, FAQ page, category page
- Primary keyword: the main search term this page should rank for
- Page URL (full, canonical)
- Site name and brand
- Page content summary (or the content itself)
- OG image URL (use
https://example.com/og-image.pngas a placeholder if not provided) - Author name (for articles)
- Publication date (for articles)
-
Generate the title tag:
- Length: 50–60 characters (never exceed 60)
- Format:
Primary Keyword — Brand NameorPrimary Keyword: Descriptive Subtitle - Put the primary keyword first (or as close to the beginning as possible)
- Do not keyword-stuff — the title must read naturally
- For homepages:
Brand Name — Short Value Proposition
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.
