Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Real-world Active Directory environment constraints that silently break attacks when ignored: NTLM disabled (Kerberos fallback), AES-only KDCs (RC4 blocked by GPO), LDAP signing and channel binding requiring LDAPS on 636, Kerberos clock skew (KRB_AP_ERR_SKEW), SPNs that must be FQDNs never short names or IPs (the misleading invalidCredentials), Protected Users / LAPS / gMSA / MachineAccountQuota, LDAP 1000-object paging, and VPN latency. Use this whenever a bind, TGT request, LDAP query, or SMB…

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/'ad-environment-constraints' ] || [ -L ~/.agents/skills/'ad-environment-constraints' ]; then echo 'A skill folder named ad-environment-constraints already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ADScanPro/Claude-AD' "$d" && git -C "$d" checkout --quiet '73efec51207f6f740cb398e1c490e5edd60c1113' -- 'skills/ad-environment-constraints' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/ad-environment-constraints' ~/.agents/skills/'ad-environment-constraints' && 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/'ad-environment-constraints' ~/.claude/skills/'ad-environment-constraints' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
