Evaluate interface-level usability using Jakob Nielsen's 10 heuristics (1994). This complements Downe's 15 Good Services principles: Downe checks end-to-end SERVICE quality, Nielsen checks screen-level INTERFACE quality. Both are needed for user-facing work.
Usability Check 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/usability-check/ and loads when your prompt matches the skill's trigger.
The Usability Check skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It is part of the open ClaudSkills registry, a community-curated catalog of 56,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/usability-check curl -L https://claudskills.com/skills/usability-check/SKILL.md \ -o ~/.claude/skills/usability-check/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/usability-check/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/usability-check/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\usability-check\SKILL.md on Windows. See the full install guide for step-by-step instructions.
The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
