Static ReDoS (Regular Expression Denial of Service) vulnerability scanner and regex quality auditor for codebases. Walks all source files to extract regex literals, detects catastrophic backtracking patterns (nested quantifiers, overlapping alternation, unbounded repetition on complex groups), severity-ranks each finding as CRITICAL/HIGH/MEDIUM, reports file and line number with the dangerous sub-pattern highlighted, identifies high-risk call sites (HTTP request handlers, form validators, URL p…

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/'phy-regex-audit' ] || [ -L ~/.agents/skills/'phy-regex-audit' ]; then echo 'A skill folder named phy-regex-audit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LeoYeAI/agent-master-skills' "$d" && git -C "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/phy-regex-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/phy-regex-audit' ~/.agents/skills/'phy-regex-audit' && 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/'phy-regex-audit' ~/.claude/skills/'phy-regex-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
