web-design

web-design is a skill for Claude Code, Codex from f0d010c/stark. It costs 87 tokens per session (1,540 once invoked), scanned A, original, Apache-2.0.

A design guide for web interfaces, including websites, web apps, dashboards, landing pages, checkout flows, and component libraries. It starts by identifying the kind of screen being designed and selecting relevant guidance.

In plain words
What is it for?
Use it to design or review React, Next.js, Astro, Tailwind, and other browser-based interfaces, including responsive product screens and distinctive marketing pages.
Why use it?
It helps match layout, interaction, responsiveness, motion, and visual references to the site's actual job instead of using one generic design for every page.

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

web-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 4d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web design

Design the product surface before choosing decoration or libraries.

Context budget

Load two core references for the selected mode and no more than two conditional references. Use ../../references/ui-patterns/README.md and ../../references/web-patterns/README.md only as catalogs. Do not read every linked document.

Classify the surface

Choose one:

  • product application;
  • operational dashboard;
  • product-proof landing page;
  • campaign or cinematic page;
  • docs or API platform;
  • checkout or trust flow;
  • design system or component library;
  • targeted audit or repair.

Do not apply campaign spacing and choreography to repeated-use applications.

Choose a reference bundle

Surface Core references Conditional additions
Product app task-ergonomics.md, interaction-state-matrix.md navigation, component API, direct manipulation, responsive gate
Dashboard dashboard-insight-hierarchy.md, data-visualization-library-selection.md realistic data, adaptive composition, performance
Product landing creative-direction.md, page-proof-architecture.md conversion proof, brand motif, asset realism
Cinematic page animation-creation.md, choreography-state-machine.md cinematic landing, motion libraries, performance
Docs/API navigation-information-architecture.md, progressive-disclosure-information-scent.md typography, search/command interaction

Design system design-system-production-loop.md, token-implementation-contract.md component API, state gallery
Audit/repair ui-audit-rubric.md, visual-repair-playbook.md usability, accessibility, fingerprint diversity

Paths in this table are under ../../references/ui-patterns/ except task-ergonomics.md, which is under ../../references/ux-patterns/.

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.
