Guides implementation of cross-platform system calls and file I/O using Bun's optimized Zig library.
The Zig System Calls skill provides specialized guidance for developers working within the Bun ecosystem to perform low-level file operations and syscalls. It emphasizes the use of the `bun.sys` library over Zig's standard `std.fs` or `std.posix` modules to ensure superior cross-platform compatibility, especially for Windows environments. By leveraging the `Maybe(T)` union type, the skill helps developers implement robust error handling that includes syscall tags, file descriptors, and automatic retry logic for interrupted calls (EINTR), resulting in more stable and performant systems code.
