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/'markdown-injection-scanner' ] || [ -L ~/.agents/skills/'markdown-injection-scanner' ]; then echo 'A skill folder named markdown-injection-scanner already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tranhieutt/software_development_department' "$d" && git -C "$d" checkout --quiet 'e5ba80930fee2512afce5b2def5048b63564e0d4' -- '.claude/skills/markdown-injection-scanner' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/markdown-injection-scanner' ~/.agents/skills/'markdown-injection-scanner' && 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/'markdown-injection-scanner' ~/.claude/skills/'markdown-injection-scanner' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
