phy-deserialization-audit

95 / 100 · Low risk

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

Unsafe deserialization vulnerability scanner (OWASP A08:2021). Detects Python pickle/yaml/eval, Java ObjectInputStream/XStream/XMLDecoder, PHP unserialize, Ruby Marshal.load, Node.js eval/new Function/vm, Go gob with interface{}. Traces HTTP input sources to dangerous sinks, classifies CRITICAL/HIGH/MEDIUM, outputs CWE/CVE mappings and per-language fix snippets. Zero competitors on ClawHub.

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/'phy-deserialization-audit' ] || [ -L ~/.agents/skills/'phy-deserialization-audit' ]; then echo 'A skill folder named phy-deserialization-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 "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/phy-deserialization-audit' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/phy-deserialization-audit' ~/.agents/skills/'phy-deserialization-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-deserialization-audit' ~/.claude/skills/'phy-deserialization-audit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
