Writing Zig CLI Tools

Build high-performance CLI tools in Zig using modern 0.15+ idioms. Covers project setup, argument parsing, I/O, error handling, and cross-compilation.

Use this skill when creating CLI applications in Zig, parsing command-line arguments, setting up build.zig projects, or writing robust terminal I/O code.

Supporting files: SYNTAX-GUIDE.md for 0.15+ syntax changes, BUILD-SYSTEM.md for build.zig patterns, ARGUMENT-PARSING.md for CLI argument handling.
