What it does
Contributes to and debugs Node.js core, including nodejs/node commit and PR tone, contribution workflows, native crashes, V8 performance, node-gyp builds, N-API bindings, and libuv issues. Use when drafting or reviewing a Node.js core commit or pull request, working in nodejs/node, or diagnosing C++ addons, binding.gyp failures, segfaults, native leaks, V8 deoptimizations, and event-loop internals.
When to use
Use this skill when you need deep Node.js internals expertise, including:
- C++ addon development
- V8 engine debugging
- libuv event loop issues
- Build system problems
- Compilation failures
- Performance optimization at the engine level
- Understanding Node.js core architecture
- Writing or reviewing
nodejs/nodecommits and pull request descriptions
