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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.01123 |
| Opus 5 | $0.00044 | $0.00562 |
| Sonnet 5 | $0.00018 | $0.00225 |
| Haiku 4.5 | $0.00009 | $0.00112 |
Grade A, and why
open-graph 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 9d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SEO On-Page: Open Graph
Guides implementation of Open Graph meta tags for social media previews (Facebook, LinkedIn, Slack, Discord, etc.). Pages with proper OG tags get 2–3× more clicks than bare URL links.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope (Social Sharing)
- Open Graph: Facebook-originated protocol; controls preview card when links are shared on social platforms
The 4 Essential Tags
Every shareable page requires these minimum tags:
<meta property="og:title" content="Your Page Title">
<meta property="og:description" content="Your description">
<meta property="og:image" content="https://yourdomain.com/image.png">
<meta property="og:url" content="https://yourdomain.com/page">
| Tag | Guideline |
|---|---|
| og:title | Keep under 60 chars; compelling; match page content |
| og:description | 150–200 chars; conversion-focused |
| og:image | Absolute URL (https://); 1200×630px recommended |
| og:url | Canonical URL; deduplicates shares |
Recommended Additional Tags
| Tag | Purpose |
|---|---|
| og:type | Content type: website, article, video, product |
| og:site_name | Website name; displayed separately from title |
| og:image:width / og:image:height | Image dimensions (1200×630px) |
| og:image:alt | Alt text for accessibility |
| og:locale | Language/territory (e.g., en_US); for multilingual sites |
Image Best Practices
| Item | Guideline |
|---|---|
| Size | 1200×630px (1.91:1 ratio) for Facebook, LinkedIn, WhatsApp |
| Format | JPG, PNG, WebP; under 5MB |
| URL | Absolute URL with https://; no relative paths |
| Unique | One unique image per page when possible |
Common Mistakes
- Using relative image URLs instead of absolute https://
- Images too small or wrong aspect ratio
- Empty or placeholder values
- Missing og:url (canonical)
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.
