A set of instructions for designing or restyling front-end interfaces using stored visual references inspired by products and brands such as Stripe, Vercel, Apple, or Linear. It covers layout, colors, type, spacing, component shapes, and motion.

Use it to create or restyle landing pages and other user interfaces, choose an available visual reference, and apply its implementation guidance without copying logos or claiming affiliation.

It provides a consistent design direction when building or reviewing an interface and keeps style decisions tied to the selected reference document.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Prompt Injection · line 40
Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.

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	$0.00091	$0.04152
Opus 5.5	$0.00036	$0.01661
Sonnet 5.5	$0.00018	$0.00830
Haiku 4.5	$0.00009	$0.00415

Security

Grade A, and why

ui-designer 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 1mo 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 — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UI Designer

Use this skill to create, restyle, or review UI with a visual language based on a vendored DESIGN.md reference.

The references are curated starting points, not official brand systems. Use them as inspiration for composition, tone, spacing, type, color roles, and component behavior. Do not copy logos, trademarked assets, or claim affiliation with the referenced company.

Reference Files

Design docs: references/designs/<slug>.md
Source notice: references/source-license.md

Use the reference index below when the user names a reference, asks what styles are available, or gives an ambiguous brand/style name. Then load only the selected design doc.

Style Source Contract

Every style decision must come from one vendored markdown file under skills/ui-designer/references/designs/*.md.

Use that vendored markdown as the sole style source for:

composition and layout direction
color roles and contrast
typography and spacing
component shape, borders, shadows, and motion

Use external pages, product docs, screenshots, and live websites for factual content only. Keep style selection anchored to the vendored markdown path above.
