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 | $0.00085 | $0.00905 |
| Opus 5 | $0.00043 | $0.00452 |
| Sonnet 5 | $0.00017 | $0.00181 |
| Haiku 4.5 | $0.00009 | $0.00090 |
Grade A, and why
email-marketing 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.
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.
This is a copy
97% identical to email-marketing — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Email Marketing Skill
Produce a single HTML email — centered, single column, no chrome around the email body. Treat it like a marketing artifact: one big idea, one CTA.
Workflow
- Read the active DESIGN.md (injected above). Email leans on the display font more than any other surface — pick the loudest type token in the DS for the headline lockup.
- Pick the brand + product from the brief. Generate a real wordmark, a real product name, and one real benefit sentence — no placeholders.
- Layout, in order, all centered inside a 600–680px column on a tinted
page background (so the email body looks like an email, not the page):
- Masthead — wordmark on the left + 3 short nav links (SHOP, JOURNAL, MEMBERS) on the right. Thin underline.
- Hero block — a 16:9 product image placeholder. Use a DS-tinted gradient or a stylized SVG silhouette of the product (shoe, bottle, headphones, whatever the brief implies). Add a tiny brand stamp on the top-left and a colorway tag on the bottom-left.
- Eyebrow — small caps, accent color, separated by
·characters (e.g. "NEW · MAX-CUSHION TRAINER · EMBER FLARE"). - Headline lockup — 2–3 line headline using the display font, all caps,
extra-tight tracking. Apply a slight skew (
transform: skew(-6deg)) on one accent word to give it a sporty parallelogram feel. - Body — 2–3 sentence paragraph, left-aligned, body font.
- Primary CTA — solid pill or block button. One only.
- Specs grid — 2×2 grid of (big number + unit + label) callouts using the display font for the numbers.
- Footer — wordmark, address line, unsubscribe + view-in-browser links.
- Write a single HTML document:
<!doctype html>through</html>, CSS inline.- Center the column with
margin: 0 auto. Setbody { background: <tint> }so the email-on-page metaphor reads. - No external images — use inline SVG or DS-tinted gradient blocks for the product photo.
data-od-idon the masthead, hero, headline, CTA, specs.
- Self-check:
- Email reads top to bottom in 8–10 seconds.
- One CTA. Accent appears at most twice (eyebrow + CTA, or headline word).
- Looks legible on a 480px window (column reflows, type drops one step).
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
