nodejs-core

Use this skill when you need deep Node.js internals expertise, including: Read individual rule files for detailed explanations and code examples: Apply deep knowledge of Node.js internals across these domains: V8 optimization tracing: Event loop lag detection: Native addon debugging (gdb): Heap snapshot for memory leaks: Segfault / crash in native addon: V8 deoptimization / performance regression: Build failure (node-gyp / binding.gyp): Always consider both JavaScript-level and native-level causes, explain performance implications and trade-offs, and indicate the stability status of any experimental features discussed. Code examples should demonstrate Node.js internals patterns and be production-ready, accounting for edge cases typical developers might miss. - 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 - rules/v8-garbage-collection.md - Scavenger, Mark-Sweep, Mark-Compact, generational GC - rules/v8-hidden-classes.md - Hidden classes, inline caching, optimization - rules/v8-jit-compilation.md - TurboFan, optimization/deoptimization patterns - rules/libuv-event-loop.md - Event loop phases, timers, I/O, idle, check, close - rules/libuv-thread-pool.md - Thread pool size, blocking operations, UV_THREADPOOL_SIZE -...
