What is product-ui-ux-design?

A guide for designing and checking user-facing interfaces, including layout, interactions, visual details, accessibility, and loading, empty, and error states.

Use it to design or review web, app, desktop, mini-program, or terminal interfaces and decide whether they are ready to ship.

It helps find confusing flows, incomplete states, accessibility problems, and inconsistent design before launch.

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	$0.00068	$0.03431
Opus 5	$0.00034	$0.01716
Sonnet 5	$0.00014	$0.00686
Haiku 4.5	$0.00007	$0.00343

Security

Grade A, and why

product-ui-ux-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 12d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Product UI/UX Design Skill

Own product-facing design decisions and acceptance across the full capability surface: user/task fit, information architecture, visual system and layout rhythm, component semantics, interaction flows, behavioral and aesthetic logic, micro-feedback, empty/error/loading states, accessibility, perceived performance, adaptation, launch acceptance, iteration signals, AI-assistant patterns, trust-sensitive data patterns, source-selection guardrails, and evidence-backed design verdicts.

Use this skill for product surfaces across web, app, mini-program, desktop, and terminal/TUI. Product category and source provenance do not define the target design. A component library is rendering vocabulary, not a substitute for deciding hierarchy, state completeness, interaction quality, trust, or visual craft.

Owner boundary

This skill owns design intent, design hypotheses, acceptance criteria, and the final design verdict.
testing-strategy owns assertion-layer and rendered-evidence-layer selection, automated proof, and test sufficiency.
Each changed or claim-bearing backend/config/content/inference owner owns its producer artifact or version identity, execution environment, and API/event/log/output runtime facts.
The complete affected client-owner set owns implementation and runtime evidence: React web → web-react-dev; Vue/Svelte/static/vendor/other web → its installed owner or fail-closed project-convention lookup; native mobile/host → app-cross-platform-dev; mini-app → miniapp-product-dev; terminal/CLI/TUI → terminal-cli-dev; Electron/desktop/TV shell → its installed owner or the same lookup. Composite hosts keep separate content and shell members.
feature-risk-router owns risk grading for destructive, public, financial, permission, privacy, legal/compliance, or other high-impact changes.
product-rd-workflow owns a cross-stage product delivery lifecycle; a narrow UI/UX task can use this skill directly.
skill-extraction-workflow owns changes to this skill, its routing, rules, and references.

Changes

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.
