90 / 100 · Low risk

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

This skill should be used when the user asks to "test for broken authentication vulnerabilities", "assess session management security", "perform credential stuffing tests", "evaluate password policies", "test for session fixation", or "identify authentication bypass flaws". It provides comprehensive techniques for identifying authentication and session management weaknesses in web applications.

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/'broken-authentication' ] || [ -L ~/.agents/skills/'broken-authentication' ]; then echo 'A skill folder named broken-authentication already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/zebbern/claude-code-guide' "$d" && git -C "$d" checkout --quiet '84cb1c68461189c5a285948f95b5de20813c029b' -- 'skills/broken-authentication' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/broken-authentication' ~/.agents/skills/'broken-authentication' && 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/'broken-authentication' ~/.claude/skills/'broken-authentication' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
