90 / 100 · Low risk

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

Techniques to hijack OAuth flows by stopping redirects, leaking authorization codes, and exploiting popup or iframe name collisions. Use when testing OAuth implementations, especially when you have XSS on a subdomain, an open redirect, or a way to prevent callback consumption.

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