zig-best-practice
NewComprehensive Zig best practices for memory safety, error handling, comptime patterns, memory layout, thread safety, smart pointers, and C interop.
Summary
This skill provides comprehensive Zig best practices for writing safe, performant, and maintainable code, covering memory safety, error handling, comptime patterns, concurrency, and C interop.
- It draws from production codebases like TigerBeetle, Bun, libxev, and Ghostty to offer battle-tested patterns.
Overview
A Claude Code plugin providing comprehensive Zig best practices for writing safe, performant, and maintainable Zig code.
Patterns Covered (10 Sections)
- Memory Safety — errdefer chains, arena allocators, poisoning, resource grouping
- Infallible Runtime Operations — AssumeCapacity philosophy across all container types
- Error Handling — narrow error sets, exhaustive switches, error composition
- Comptime & Generics — type functions,
@fieldParentPtr,@Type,@embedFile, deep equality - Memory Layout & Copy Safety — extern structs, SIMD, mmap, cache alignment, packed structs
- Naming & Style — snake_case/PascalCase rules, named arguments, sized types
- Code Organization — imports, intrusive data structures, object pools, ref counting
- Thread Safety & Concurrency — threadlocal, lock-free MPSC, atomics
- Smart Pointer Patterns — copy-on-write, RefCount mixin
- C Interop — export fn, callconv, allocator bridging, pointer smuggling
Sources
Patterns extracted from production codebases:
- •TigerBeetle — financial transactions database
- •Bun — JavaScript runtime
- •libxev — cross-platform event loop
- •Ghostty — terminal emulator

Usage Examples
/zig-best-practice How do I use an arena allocator with errdefer to manage memory in a parser?
Show me a comptime function that generates a type-safe HashMap for any key-value pair.
I need to call a C function that returns an allocated string; how do I bridge allocators safely?

What can I use zig-best-practice for?
zig-best-practice is useful for: Implement errdefer chains and arena allocators to prevent memory leaks in complex functions.; Apply AssumeCapacity across ArrayList, HashMap, and other containers to eliminate runtime bounds checks.; Design narrow error sets and exhaustive switch statements for robust error handling.; Use comptime type functions and @fieldParentPtr for generic data structures without runtime overhead.; Optimize memory layout with extern structs, packed structs, and cache alignment for performance-critical code.; Bridge C libraries safely using export fn, callconv, and allocator smuggling patterns..
