Abuse user-controlled TeX/LaTeX macros in MathJax and KaTeX renderers to override built-in operators, spoof rendered content, inject links/scripts, or exhaust the renderer. Use when an app renders user-supplied math (GitHub-style Markdown math, wikis, comments, chat, LMS, note apps) via MathJax or KaTeX.

Works with any agent that supports SKILL.md skills.

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/'math-rendering-macro-injection' ] || [ -L ~/.agents/skills/'math-rendering-macro-injection' ]; then echo 'A skill folder named math-rendering-macro-injection already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dreadnode/capabilities' "$d" && git -C "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/math-rendering-macro-injection' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/math-rendering-macro-injection' ~/.agents/skills/'math-rendering-macro-injection' && 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/'math-rendering-macro-injection' ~/.claude/skills/'math-rendering-macro-injection' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
