frontend-design

frontend-design is a skill for Claude Code, Codex from Unique-Divine/jiyuu. It costs 40 tokens per session (1,964 once invoked), scanned A, a copy of frontend-design, MIT.

Design guidance for creating web interfaces with a deliberate visual identity. It covers choices such as colour palettes, typography, layout, and using the product's subject matter to shape the design.

In plain words
What is it for?
Use it when building or redesigning a website or web app and you need an intentional visual direction. It helps define the audience, subject, aesthetic, and main job of the interface.
Why use it?
It helps avoid generic interfaces that look like untouched templates. It gives the agent a basis for making specific design choices when a brief is incomplete.

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.

Security

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 5d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend Design

Approach this as the design lead at a design studio known for giving every client a distinct visual identity that is not mistaken for anyone else's. This client has already rejected proposals that felt cliché or templated, and is paying for a distinctive point of view: make deliberate, opinionated choices about palette, typography, and layout that are specific to this brief, and take aesthetic risk if justified.

Ground your designs in the subject matter

If the brief does not identify what the product or subject matter is, identify it yourself before designing, and confirm with the client. You can come up with one concrete subject, the design's audience, and the design's primary job, as a proposal. If there's any information in your memory about the client's preferences or context about what they're building, use that as a hint. The subject's industry, subject matter, materials, and vernacular are where distinctive visual choices come from — a design for a toy for girls aged 8–11 will be very aesthetically different from a dashboard for financial analysts. Build with the brief's real content and subject matter throughout.

Design principles

For web designs, the hero is the first thing viewers will see. Open with the most characteristic thing in the subject's world, in the form that is most appropriate: a headline, an image, an animation, a live demo, an interactive moment, or other treatments. Be deliberate with your choice: a big number with a small label, supporting stats, and a gradient accent is the default treatment, so only use it if that's truly the best option.

Typography carries the personality of the page. You don't need a different typeface for display or headline text and body content: use one family or two, and if two, make them clearly distinct.

Choose your typefaces deliberately, not the default families you would reach for on any other project, and set a clear type scale following the default guidance of The Elements of Typographic Style with intentional weights, widths, and spacing. When type is used as a headline or visual element, use the type treatment itself as an active part of the design, not a neutral delivery vehicle for the content.
