Zig

When to use

• Editing .zig files.
• Modifying build.zig or build.zig.zon.
• Defining custom zig build steps (for example zig build ci) and CI/build-cache wiring.
• Zig builds/tests, dependencies, cross-compilation.
• Any Zig work requires fuzz testing (coverage-guided or fuzz-style).
• Performance tuning: SIMD (std.simd / @Vector) and threading (std.Thread.Pool).
• Comptime, reflection, codegen.
• Allocators, ownership, zero-copy parsing.
• C interop.

Baseline (required)

• Zig 0.15.2.
• Integrated fuzzer is the default: std.testing.fuzz + zig build test --fuzz.
• No compatibility work for older Zig unless explicitly requested.
