dom-vulnerability-detection

80 / 100 · Low risk

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

By dreadnode/capabilities (GitHub) · security · 22 stars · scanned at commit 3ceeb34

DOM-based XSS and client-side vulnerability detection via dynamic analysis -- trace attacker-controlled sources to dangerous sinks, audit postMessage handlers, test CSTI in Angular/Vue/htmx, and check for DOM clobbering. Use when auditing JavaScript code, reviewing client-side security, analyzing DOM manipulation, or testing postMessage handlers.

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