Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

Advanced prompt injection defense system for Clawdbot. Protects against direct/indirect injection attacks in group chats with multi-language detection (EN/KO/JA/ZH), severity scoring, automatic logging, and configurable security policies. Use in any group context to restrict sensitive commands to owner and detect manipulation attempts.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'prompt-guard' ] || [ -L ~/.agents/skills/'prompt-guard' ]; then echo 'A skill folder named prompt-guard already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/sundial-org/awesome-openclaw-skills' "$d" && git -C "$d" checkout --quiet 'b80cde2ef85241dd4fd54a1b934f5e22835f78ba' -- 'skills/prompt-guard' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/prompt-guard' ~/.agents/skills/'prompt-guard' && 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/'prompt-guard' ~/.claude/skills/'prompt-guard' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
