Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Deep code optimization audit using parallel specialist agents that hunt performance anti-patterns via pattern-based detection, avoiding anchoring bias. Covers DB queries, memory leaks, algorithmic complexity, concurrency, bundle size, dead code, I/O/network, rendering, caching, and build config. Use when asked to optimize code, find performance issues or bottlenecks, speed up an app, reduce latency, detect code smells, or run a performance/quality audit.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'code-optimizer' ] || [ -L ~/.agents/skills/'code-optimizer' ]; then echo 'A skill folder named code-optimizer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/open-gsd/gsd-pi' "$d" && git -C "$d" checkout --quiet 'c0bc9c4e7e0a8581aeac3af397031dc3a63d012e' -- 'src/resources/skills/code-optimizer' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/resources/skills/code-optimizer' ~/.agents/skills/'code-optimizer' && 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/'code-optimizer' ~/.claude/skills/'code-optimizer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
