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

Exploit type confusion vulnerabilities where applications receive unexpected data types (array instead of string, null instead of integer, object instead of scalar). Use when testing parameter handling, auth bypasses, or input validation across PHP, Ruby, JS, Python, Java, and Go.

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/'type-confusion-testing' ] || [ -L ~/.agents/skills/'type-confusion-testing' ]; then echo 'A skill folder named type-confusion-testing 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 "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/type-confusion-testing' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/type-confusion-testing' ~/.agents/skills/'type-confusion-testing' && 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/'type-confusion-testing' ~/.claude/skills/'type-confusion-testing' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
