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

This skill covers designing and implementing security zones and conduits for industrial automation and control systems (IACS) per IEC 62443-3-2. It addresses zone partitioning based on risk assessment, assigning Security Level targets (SL-T), designing conduit security controls, implementing microsegmentation with industrial firewalls, and validating zone architecture through traffic analysis and penetration testing against the Purdue Reference Model.

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/'implementing-iec-62443-security-zones' ] || [ -L ~/.agents/skills/'implementing-iec-62443-security-zones' ]; then echo 'A skill folder named implementing-iec-62443-security-zones already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/plurigrid/asi' "$d" && git -C "$d" checkout --quiet '293ce9f76e3abcd5ba18db284688bc0d9ac6691d' -- 'plugins/asi/skills/implementing-iec-62443-security-zones' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/asi/skills/implementing-iec-62443-security-zones' ~/.agents/skills/'implementing-iec-62443-security-zones' && 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/'implementing-iec-62443-security-zones' ~/.claude/skills/'implementing-iec-62443-security-zones' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
