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 | $0.00034 | $0.02004 |
| Opus 5 | $0.00017 | $0.01002 |
| Sonnet 5 | $0.00007 | $0.00401 |
| Haiku 4.5 | $0.00003 | $0.00200 |
Grade A, and why
minimalist-ui 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
100% identical to minimalist-ui — 0 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.

Protocol: Premium Utilitarian Minimalism UI Architect
1. Protocol Overview
Name: Premium Utilitarian Minimalism & Editorial UI Description: An advanced frontend engineering directive for generating highly refined, ultra-minimalist, "document-style" web interfaces analogous to top-tier workspace platforms. This protocol strictly enforces a high-contrast warm monochrome palette, bespoke typographic hierarchies, meticulous structural macro-whitespace, bento-grid layouts, and an ultra-flat component architecture with deliberate muted pastel accents. It actively rejects standard generic SaaS design trends.
2. Absolute Negative Constraints (Banned Elements)
The AI must strictly avoid the following generic web development defaults:
- DO NOT use the "Inter", "Roboto", or "Open Sans" typefaces.
- DO NOT use generic, thin-line icon libraries like "Lucide", "Feather", or standard "Heroicons".
- DO NOT use Tailwind's default heavy drop shadows (e.g.,
shadow-md,shadow-lg,shadow-xl). Shadows must be practically non-existent or heavily customized to be ultra-diffuse and low opacity (< 0.05). - DO NOT use primary colored backgrounds for large elements or sections (e.g., no bright blue, green, or red hero sections).
- DO NOT use gradients, neon colors, or 3D glassmorphism (beyond subtle navbar blurs).
- DO NOT use
rounded-full(pill shapes) for large containers, cards, or primary buttons. - DO NOT use emojis anywhere in code, markup, text content, headings, or alt text. Replace with proper icons or clean SVG primitives.
- DO NOT use generic placeholder names like "John Doe", "Acme Corp", or "Lorem Ipsum". Use realistic, contextual content.
- DO NOT use AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen", "Game-changer", "Delve". Write plain, specific language.
3. Typographic Architecture
The interface must rely on extreme typographic contrast and premium font selection to establish an editorial feel.
- Primary Sans-Serif (Body, UI, Buttons): Use clean, geometric, or system-native fonts with character. Target:
font-family: 'SF Pro Display', 'Geist Sans', 'Helvetica Neue', 'Switzer', sans-serif. - Editorial Serif (Hero Headings & Quotes): Target:
font-family: 'Lyon Text', 'Newsreader', 'Playfair Display', 'Instrument Serif', serif. Apply tight tracking (letter-spacing: -0.02emto-0.04em) and tight line-height (1.1). - Monospace (Code, Keystrokes, Meta-data): Target:
font-family: 'Geist Mono', 'SF Mono', 'JetBrains Mono', monospace. - Text Colors: Body text must never be absolute black (
#000000). Use off-black/charcoal (#111111or#2F3437) with a generousline-heightof1.6for legibility. Secondary text should be muted gray (#787774).
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.

minimalist-ui is a skill published in the GitHub repository ne11nn/cantos-plugin (1 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 2,004 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to minimalist-ui, differing in 0 lines, and is treated as a copy.
