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 | $0.00057 | $0.00728 |
| Opus 5 | $0.00028 | $0.00364 |
| Sonnet 5 | $0.00011 | $0.00146 |
| Haiku 4.5 | $0.00006 | $0.00073 |
Grade A, and why
blog-post 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 8d 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
91% identical to blog-post — 5 lines 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Post Skill
Produce a single long-form article page — editorial layout, no chrome.
Workflow
- Read the active DESIGN.md (injected above). Lean into the typography tokens — long-form is 70% type, 20% image, 10% chrome.
- Pick the topic from the brief and write a real article — at least 600 words across 4–6 H2 sections. No lorem ipsum.
- Sections, in order:
- Masthead — small wordmark + 4–6 nav links, plain.
- Article header — category eyebrow, headline (display token, large), deck (1–2 sentence subhead), author name + role + date.
- Hero image — a 16:9 placeholder block using a DS-tinted gradient or solid fill (no external images). Add a 1-line caption underneath.
- Body — alternating prose paragraphs with at least:
- 1 pull quote (large display type, accent rule on the left).
- 1 figure (image placeholder + caption).
- 1 list (numbered or bulleted).
- 1 inline blockquote.
- Author footer — author avatar (initials in a circle), bio paragraph.
- Related — 3 cards linking to other posts. Each card: tiny image block, title, 1-line excerpt, date.
- Write a single HTML document:
<!doctype html>through</html>, CSS inline.- Article body uses the DS body font, centered, max-width per DS layout rule (typically 680–720px).
- Drop caps (
first-letter) only if the DS mood is editorial / serif — skip on tech-y DSes. data-od-idon the headline, hero, body, pull quote, related grid.
- Self-check:
- Type hierarchy is unambiguous — H1 is clearly the headline; H2s are section dividers; pull quotes do not compete with H1.
- Line length 60–75 chars for body prose.
- Accent appears at most twice (eyebrow + pull-quote rule, or one link).
- The page reads like a magazine, not a marketing landing.
Output contract
Emit between <artifact> tags:
<artifact identifier="post-slug" type="text/html" title="Article Title">
<!doctype html>
<html>...</html>
</artifact>
What ships with it
2 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.
