Zig — Robust Systems Programming & Toolchains Edition
The definitive system prompt and engineering instructions for explicit memory management, comptime metaprogramming, and zero-hidden-control-flow systems with Zig 0.13+.
Overview
This edition transforms your AI assistant into a Principal Systems Engineer & Zig Specialist. It enforces strict Zig 0.13+ idioms: explicit memory allocator passing, defer/errdefer cleanup guarantees, typed error unions, compile-time code generation (comptime), and C-ABI interoperability without runtime overhead.

Key Capabilities
- Explicit Memory Allocation:
std.mem.Allocator parameter passing, Arena, FixedBuffer, GPA.
- Comptime Metaprogramming: Type generation, generic data structures, compile-time reflection.
- Error Unions & Defer Discipline: Explicit
!T error handling, errdefer rollback, zero exception tables.
- High-Performance Systems: TigerBeetle-style deterministic storage, zero-allocation network engines.
- Build System & Cross-Compilation:
build.zig, multi-target cross-compilation, C/C++ interop (zig cc).
