Fine to try.

Use this skill when distinguishing the two mental-model types — system models (how the user thinks the system works) and interaction models (how the user thinks they should use it). Trigger when designing onboarding (which model to teach), reviewing user confusion (which model is wrong), or building documentation (which model to explain). Sub-aspect of `mental-model`; read that first.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'mental-model-system-vs-interaction' ] || [ -L ~/.agents/skills/'mental-model-system-vs-interaction' ]; then echo 'A skill folder named mental-model-system-vs-interaction 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 "$d" checkout --quiet '3e1e6b20ffc28f42923e391f29f075c424e19e64' -- 'plugins/HDeibler/universal-design-principles/plugins/cognition-and-learnability-principles/skills/mental-model-system-vs-interaction' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/HDeibler/universal-design-principles/plugins/cognition-and-learnability-principles/skills/mental-model-system-vs-interaction' ~/.agents/skills/'mental-model-system-vs-interaction' && 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/'mental-model-system-vs-interaction' ~/.claude/skills/'mental-model-system-vs-interaction' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
