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/'principle-treat-messages-as-data' ] || [ -L ~/.agents/skills/'principle-treat-messages-as-data' ]; then echo 'A skill folder named principle-treat-messages-as-data already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mintuz/skills' "$d" && git -C "$d" checkout --quiet '8cc95d9146ca13624d48611702d0ab12bbe7756a' -- 'src/principle/skills/principle-treat-messages-as-data' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/principle/skills/principle-treat-messages-as-data' ~/.agents/skills/'principle-treat-messages-as-data' && 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/'principle-treat-messages-as-data' ~/.claude/skills/'principle-treat-messages-as-data' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
