75 / 100 · Review before installing

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

By alirezarezvani/claude-skills (GitHub) · coding · 29,577 stars · scanned at commit 91a1dda

Use for a slow endpoint, memory leak, CPU spike, large bundle or performance budget in Node.js, Python or Go, before optimizing. Measures before and after with performance_profiler.py, flamegraphs and k6 load tests.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'performance-profiler' ] || [ -L ~/.agents/skills/'performance-profiler' ]; then echo 'A skill folder named performance-profiler already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/alirezarezvani/claude-skills' "$d" && git -C "$d" checkout --quiet '91a1ddaab1ae8fe95b8ecd3e98419458db86a992' -- 'engineering/skills/performance-profiler' && mkdir -p ~/.agents/skills && cp -R "$d"/'engineering/skills/performance-profiler' ~/.agents/skills/'performance-profiler' && 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/'performance-profiler' ~/.claude/skills/'performance-profiler' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
