SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you write consistent, idiomatic Zig code by standardizing style, memory management, error handling, and compile-time patterns, reducing bugs and review friction.

Core Features & Use Cases

  • Zig Style Guidance: Follow the Zig Style Guide for readable, maintainable code.
  • Tooling Expectations: Use zig fmt and zig test as the baseline workflow for formatting and validation.
  • Memory and Safety Discipline: Pass explicit allocators first, rely on GeneralPurposeAllocator in debug, and use defer and errdefer for cleanup.
  • Language Features: Apply error unions and comptime for robust error handling and compile-time metaprogramming.
  • Use Case: Ideal for implementing or reviewing Zig modules that need predictable allocation behavior, safe resource cleanup, and idiomatic compiler-friendly structure.

Quick Start

Use this skill to review or generate Zig code that follows the listed style, memory, safety, and testing standards.

Frequently Asked Questions about lang-zig

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I manage allocators and memory safety in Zig?▼

Zig memory safety requires passing explicit allocators first and relying on GeneralPurposeAllocator in debug. You must use defer and errdefer for predictable resource cleanup and safe lifetime management.

What is the best way to handle errors and cleanup in Zig?▼

Zig error handling uses error unions combined with errdefer for rollback safety. Applying errdefer alongside standard defer guarantees safe resource cleanup whenever error unions return a failure.

How do I standardize my Zig code formatting and testing workflow?▼

Standardizing Zig workflows requires using zig fmt for code formatting and zig test for validation as your baseline. Following the Zig Style Guide ensures readable, maintainable modules throughout development.

When should I use comptime in Zig projects?▼

Use comptime in Zig for compile-time metaprogramming and robust compile-time logic. Comptime-aware design allows you to evaluate expressions during compilation, generating idiomatic compiler-friendly structures.

Does idiomatic Zig require explicit allocator passing for every function?▼

Idiomatic Zig requires explicit allocator passing to ensure predictable allocation behavior. Passing allocators as the first argument standardizes memory management and prevents hidden allocation side effects.

Why does my Zig code fail review due to inconsistent style?▼

Inconsistent Zig style often stems from ignoring the Zig Style Guide and skipping zig fmt. Standardizing your implementation and refactoring practices reduces bugs and review friction significantly.
