What is frontend-design-pro?

A shared set of rules for choosing the visual style, layout, typography, media and motion of self-contained HTML stories. It is used by the design and coding stages of the workflow.

Use it when planning or coding a multimedia article with charts, images, video, audio, maps or interactive elements. It helps choose a theme and apply it consistently in CSS and components.

It helps prevent data stories from looking like generic templates or collections of unrelated components. It gives the page a consistent editorial style and guides accessible implementation.

Token cost

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	$0.00129	$0.01278
Opus 5.5	$0.00052	$0.00511
Sonnet 5.5	$0.00026	$0.00256
Haiku 4.5	$0.00013	$0.00128

Security

Grade A, and why

frontend-design-pro 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.

How it starts

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Design

A shared design system for building beautiful, distinctive, multimedia-rich HTML stories. This is not a pipeline stage; it is a library the Designer reads to choose a visual language and the Programmer reads to implement it, so output looks like an editorial product, not a default template.

When to use

Designer: before writing page_rhythm and per-section visuals, pick a theme and component vocabulary from here. Borrow tokens, layout, and component recipes; record the chosen theme in designer.json page_rhythm.
Programmer: implement the chosen theme's tokens as CSS :root variables and build each visual with the matching component recipe and motion/accessibility rules here.

Core principles

Editorial, not generic. Avoid the default-AI look (bootstrap blue, purple gradient hero, everything centered, one system font, evenly-spaced soulless cards). Commit to one bold idea per story. See references/themes.json → anti_patterns.
Rich media by default. A story should use multiple channels well — charts, images, video, audio, interactives/maps — each presented with craft, not dumped in. See references/media_presentation.json.
One system, themed per story. All color/type/space/shadow flow from CSS :root tokens so the whole page is coherent and re-themeable. See references/design_tokens.json for tokens and references/typography.json for concrete file://-safe font-pairing stacks.
Structure carries the reading. A clear content column, deliberate full-bleed moments, and consistent section rhythm. See references/layout.json.
Motion and access are part of the design. Subtle scroll reveals and transitions, always respecting prefers-reduced-motion, AA contrast, focus states, and "never autoplay sound." See references/motion.json for motion tokens, choreography, accessibility, and the anti-slop checklist.
Self-contained. Single HTML file; allowed CDNs only (Vega-Embed, Leaflet, optionally D3/PDF.js); inline data; works on file://.

Changes

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.
