Produce a scored heuristic critique of the UI using Nielsen's 10 + 6 design laws + optional persona walkthroughs. Outputs a machine-parseable scorecard plus a 0-100 UsabilityScore (the judged companion to the deterministic UICraftScore). Invoke when the user asks for heuristic on their UI, or mentions 'heuristic' alongside design / UI / frontend work.

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'heuristic' ] || [ -L ~/.agents/skills/'heuristic' ]; then echo 'A skill folder named heuristic already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/educlopez/ui-craft' "$d" && git -C "$d" checkout --quiet '9dd5f45bac58ac3995f9f0c60da8028a6751e5b7' -- '.agents/skills/heuristic' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/heuristic' ~/.agents/skills/'heuristic' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'heuristic' ~/.claude/skills/'heuristic' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
