Foundational principles for evaluating and designing usable interfaces. Apply these as a review checklist and as design constraints from the start — not only as a post-hoc audit tool.
Nielsen Usability Heuristics is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/nielsen-usability-heuristics/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when auditing an interface, designing interaction flows, writing error messages, or reviewing any UI for usability issues.
The Nielsen Usability Heuristics Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
