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 | $0.00167 | $0.02486 |
| Opus 5 | $0.00084 | $0.01243 |
| Sonnet 5 | $0.00033 | $0.00497 |
| Haiku 4.5 | $0.00017 | $0.00249 |
Grade A, and why
49-html-email-template-global 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HTML Email Template (Global)
Email HTML is not web HTML: it needs table layout, inline CSS, and avoidance of everything clients do not support. The bar is simple — it looks right in Gmail, Apple Mail, Outlook, and Yahoo, and it reads on a 375px phone. No exceptions. Content and sequence come from 14-email-marketing-global; this skill handles the code.
Information gathering
Read the brand guideline (46-brand-guideline-global) and the email content from 14-email-marketing-global if available. If information is missing, ask up to 4 questions:
- Email type and layout? Welcome, broadcast, nurture, offer, or transactional — single column, two columns with a product image, or a multi-section newsletter?
- Which sections? Header, hero, body, social proof, CTA, footer — is there a hero image?
- Is the copy written? Or should the template ship with placeholders? Where does the primary CTA link?
- Which ESP sends it? Klaviyo, Mailchimp, HubSpot, Brevo, Braze, or other — merge tag syntax differs per platform.
Principles
- Table layout only — no div/flexbox/grid/float/position:absolute. Outlook on Windows renders through the Word engine and does not support them.
- Inline all CSS. Gmail can strip
<style>blocks; keep only media queries and dark-mode rules in<style>, and inline everything else. - 600px maximum width, degrading to 375px.
- System-font fallbacks: '[body font]', Arial, Helvetica, sans-serif. Never depend on a web font — many clients will not load it.
- Every
imgneeds alt text plus width and height attributes so a blocked-image inbox still reads correctly. - Unsubscribe link and a physical postal address are legally required (CAN-SPAM in the US, GDPR and PECR in the EU/UK, CASL in Canada). Honor opt-outs promptly.
- Test on mobile first. The majority of opens are on a phone.
- One self-contained .html file, under 100KB — Gmail clips messages past roughly 102KB.
Workflow
1. Choose the layout
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.
