hunt-xss

69 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By elementalsouls/Claude-BugHunter (GitHub) · security · 5,515 stars · scanned at commit d5dcc53

Hunting skill for xss vulnerabilities. Built from 174 public bug bounty reports. Use when hunting xss on any target. For markup injection that reflects raw HTML but does NOT execute JavaScript (no `<script>`/event-handler execution), see hunt-html-injection — escalate here once script execution is possible.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'hunt-xss' ] || [ -L ~/.agents/skills/'hunt-xss' ]; then echo 'A skill folder named hunt-xss already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/elementalsouls/Claude-BugHunter' "$d" && git -C "$d" checkout --quiet 'd5dcc5347675ed431488e0a0e46749e4918aa194' -- 'skills/hunt-xss' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/hunt-xss' ~/.agents/skills/'hunt-xss' && 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/'hunt-xss' ~/.claude/skills/'hunt-xss' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
