Apply deliberate dissimilarity (contrast) to distinguish elements that need to be perceived as different — primary vs. secondary actions, normal vs. error states, foreground vs. background, the one important thing vs. the rest. Use when you want to emphasize a single element, distinguish roles, or break up a too-uniform layout. Contrast is similarity's complement: similarity groups, contrast separates.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'similarity-and-contrast' ] || [ -L ~/.agents/skills/'similarity-and-contrast' ]; then echo 'A skill folder named similarity-and-contrast already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '70b6a3a3a7c774671e45af646306e1448baf0511' -- 'plugins/HDeibler/universal-design-principles/plugins/perception-and-hierarchy-principles/skills/similarity-and-contrast' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/HDeibler/universal-design-principles/plugins/perception-and-hierarchy-principles/skills/similarity-and-contrast' ~/.agents/skills/'similarity-and-contrast' && 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/'similarity-and-contrast' ~/.claude/skills/'similarity-and-contrast' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
