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

Expert skill for Node.js-specific profiling and optimization. Use V8 CPU profiler, analyze heap snapshots, configure clinic.js tools (Doctor, Flame, Bubbleprof), debug event loop blocking, analyze async hooks performance, and optimize V8 JIT compilation.

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/'nodejs-profiling' ] || [ -L ~/.agents/skills/'nodejs-profiling' ]; then echo 'A skill folder named nodejs-profiling already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/a5c-ai/babysitter' "$d" && git -C "$d" checkout --quiet 'feb68abe397acc14f32b34984975c48fedba2b33' -- 'library/specializations/performance-optimization/skills/nodejs-profiling' && mkdir -p ~/.agents/skills && cp -R "$d"/'library/specializations/performance-optimization/skills/nodejs-profiling' ~/.agents/skills/'nodejs-profiling' && 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/'nodejs-profiling' ~/.claude/skills/'nodejs-profiling' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
