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 | $0.00065 | $0.01177 |
| Opus 5 | $0.00032 | $0.00589 |
| Sonnet 5 | $0.00013 | $0.00235 |
| Haiku 4.5 | $0.00006 | $0.00118 |
Grade A, and why
frontend-design 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 2d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Design
Create an interface with a clear point of view that serves its users and works in the existing product. Do not default to fashionable AI-generated aesthetics, decorative effects, or a familiar component-library layout when they are not justified by the brief.
1. Establish the brief
Before changing code, identify or explicitly state:
- Subject: What is being designed?
- Audience: Who uses it and what do they need to understand or do?
- Primary job: What is the one most important outcome for this page or flow?
- Context: Is this a new surface, an extension of an established product, or a redesign?
- Constraints: Existing design system, brand rules, framework, content, assets, browser support, and deadline.
For an existing product, inspect the relevant routes, components, styles, tokens, assets, and UI conventions first. Preserve purposeful conventions; do not introduce a parallel design system merely to make the page look new.
If a decision is genuinely blocked by missing product information, ask one focused question. Otherwise, make a stated, reversible assumption and proceed.
2. Set a deliberate visual direction
Write a compact design plan before implementation. Include:
- Concept: One sentence that ties the design to the subject, not a visual trend.
- Hierarchy: What a person sees first, second, and next.
- Tokens: A restrained palette (4–6 named colors), type roles, spacing rhythm, radii, borders, and shadows.
- Layout: Content regions, reading order, breakpoints, and an ASCII wireframe when the page is structurally complex.
- Signature: One memorable but useful element—such as a data treatment, interaction, visual metaphor, or editorial composition.
- Motion: The few interactions or transitions that clarify state or add atmosphere. Respect
prefers-reduced-motion.
Choose typography for role and readability. Pair display, body, and utility styles intentionally; establish a type scale and use it consistently. Use familiar defaults only when they suit the product and audience, not because they are easy.
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.

frontend-design is a skill published in the GitHub repository CODE-SAURABH/OpenSkills (2 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 1,177 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
