nw-ux-web-patterns is a skill for Claude Code from nWave-ai/nWave. It costs 33 tokens per session (1,745 once invoked), scanned A, original, MIT.

A reference for choosing web interface patterns such as navigation bars, breadcrumbs, tabs, and command palettes. It explains when each pattern fits and when to avoid it.

In plain words
What is it for?
It is for designing browser-based application interfaces, writing web acceptance criteria, and evaluating responsive layouts.
Why use it?
It helps product teams make web interfaces easier to navigate and review designs consistently. It also clarifies how the target platform and site structure affect the choice.

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

nw-ux-web-patterns 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.

Web UI Patterns

Actionable web interface patterns for requirements gathering and design review. Use when the target platform is web (browser-based applications).

Pattern When to Use When to Avoid
Top navigation bar 5-7 primary sections, marketing/content sites Deep hierarchies with 20+ sections
Side navigation Complex apps with many sections, admin dashboards Simple sites with few pages
Breadcrumbs Deep hierarchies, e-commerce categories Flat site structures
Command palette (Cmd+K) Power user tools, developer-facing apps Consumer apps targeting non-technical users
Tab bar (mobile) 3-5 primary destinations More than 5 destinations
Hamburger menu Secondary navigation, mobile space constraints Primary navigation users need frequently
Mega menu Large sites with categorized content Simple sites, mobile interfaces

Navigation must answer three questions: Where am I? Where can I go? How do I get back?

Key principles: consistent placement across all pages | highlight current location | limit primary nav to 5-7 items (Hick's Law) | provide search as alternative for content-heavy apps

Form Design

Layout

  • Labels above input fields (highest completion rates in eye-tracking studies)
  • One column layouts outperform multi-column for most forms
  • Group related fields with visual proximity and clear section headings
  • Primary action buttons left-aligned with form fields

Validation: Reward Early, Punish Late

  • Validate on blur (when user leaves field), not while typing
  • Remove error messages immediately when user corrects the field
  • Show success indicators only when helpful (e.g., password strength)
  • Validation summary at top for longer forms, plus inline errors

Error Messages Must Include

  1. What went wrong (plain language) | 2. Where the error is (highlight field) | 3. How to fix it (specific guidance, not "invalid input")

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.
