if [ -e ~/.agents/skills/'color' ] || [ -L ~/.agents/skills/'color' ]; then echo 'A skill folder named color 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 "$d" checkout --quiet '70b6a3a3a7c774671e45af646306e1448baf0511' -- 'plugins/HDeibler/universal-design-principles/plugins/perception-and-hierarchy-principles/skills/color' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/HDeibler/universal-design-principles/plugins/perception-and-hierarchy-principles/skills/color' ~/.agents/skills/'color' && 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/'color' ~/.claude/skills/'color' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
