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 | $0.00061 | $0.01157 |
| Opus 5.5 | $0.00024 | $0.00463 |
| Sonnet 5.5 | $0.00012 | $0.00231 |
| Haiku 4.5 | $0.00006 | $0.00116 |
Grade A, and why
jekyll-ui-web-designer 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 2mo 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.

Jekyll UI & Web Designer (KaTeX + Mermaid + Reveal.js)
Create clean, functional layouts and content structures for Jekyll and other static page builders, with first-class support for KaTeX, Mermaid, and slide decks.
Quick Start (default deliverables)
When asked to “build a layout” or “make a site,” produce:
_layouts/withdefault.html,page.html,post.html,slides.html_includes/withhead.html,header.html,footer.html_data/nav.ymlfor navigationassets/for CSS/JS, including Mermaid + KaTeX initindex.mdand at least one example page/postslides/with at least one Reveal.js deck page
Assumptions (unless user overrides)
- Use Jekyll with a minimal, dependency-light approach (CDN-based KaTeX/Mermaid/Reveal).
- Use KaTeX for math; keep math in source as
\( \)and\[ \]so it renders in both posts and slides. - Use client-side Mermaid: fenced code blocks with ```mermaid.

Layout Implementation Guidelines
Core layout behavior
- Keep a single
defaultlayout that defines the page chrome (header/nav/footer). - Use semantic HTML (
main,nav,header,footer) and accessible patterns. - Use responsive CSS with a readable baseline:
- max content width (e.g., 70–80ch)
- comfortable line-height
- good contrast
Navigation
Drive nav from _data/nav.yml, e.g.:
- title: Home
url: /
- title: Blog
url: /blog/
- title: Slides
url: /slides/
KaTeX
- Include KaTeX CSS/JS in
_includes/head.html(CDN). - Add
assets/js/katex-init.jsthat renders math in the document body. - Keep authoring format in Markdown/HTML as
\( ... \)and\[ ... \].
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.
