Principles for building web interfaces that feel fast, intentional, and respectful of the user's time. Every rule here is a smell test — violating one is fine if you have a reason, violating several means the UI needs work.
Web UI Best Practices is a community-contributed Claude Code skill in the growth-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/web-ui-best-practices/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when building or reviewing any user-facing web interface — dashboards, SaaS apps, marketing sites, internal tools. Covers interaction speed, navigation depth, visual restraint, copy quality, and the small details that separate polished products from rough ones.
The Web UI Best Practices Claude Code skill is built for growth marketers, product-led growth teams, founders running experiments, and performance marketing teams. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
