# Event Loop Skill Expert skill for high-performance event-driven I/O programming across platforms and runtime environments. ## Capabilities - **Platform Multiplexers**: Configure epoll (Linux), kqueue (BSD/macOS), IOCP (Windows) - **Performance Analysis**: Analyze event loop performance and identify bottlenecks - **Event Debugging**: Debug event handling issues and callback delays - **Framework Code Generation**: Generate code for libuv, Boost.Asio, Tokio, and mio - **C10K+ Optimization**: Optimize for massive concurrent connection handling - **Profiling**: Profile event loop performance with system tools - **io_uring Integration**: Implement Linux io_uring for high-performance I/O - **Timer Management**: Efficient timer wheel and hierarchical timing implementations ## Tools and Dependencies - `strace/dtrace` - System call tracing - `perf` - Linux performance analysis - `libuv` - Cross-platform async I/O - `io_uring` - Linux async I/O interface - `Tokio` - Rust async runtime - `Boost.Asio` - C++ async I/O ## Target Processes - event-driven-socket-handler.js - tcp-socket-server.js - websocket-server.js - layer4-load-balancer.js ## Usage Examples ### epoll Event Loop (C) ```c int ep

What does the event-loop skill do?
Expert skill for high-performance event-driven I/O programming and optimization
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill event-loop --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
