Static concurrency and race-condition auditor for Go, Java, Python, Node.js/TypeScript.

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