zig version, build.zig.zon, and release notes, with a dedicated reference for toolchain changes including Zig 0.16 C translation and futures. - Ownership and safety discipline: Provides concrete rules for allocator lifetimes, defer/errdefer cleanup, error sets, runtime safety modes, pointer casts, and comptime usage. - Domain references: Ships focused references for build/package graphs, comptime, FFI, performance, and toolchain changes, loaded only when the task requires them. - Use Case: When adding a feature to a Zig library that allocates memory and exposes a C ABI, the Skill walks through allocator injection, error-set design, callback lifetime rules, and the correct zig build test verification steps. ## Quick Start Ask the assistant to review or modify a Zig source file or build.zig while following the pinned toolchain's ownership, error handling, and testing conventions.High-intent search queries and answers about installing and using this skill.
Zig has no borrow checker, so every allocation needs one clear owner, lifetime, and release path. Libraries should accept a std.mem.Allocator from the caller, pair alloc with free and create with destroy, and place defer or errdefer immediately after each successful acquisition.
Run zig version first and inspect the repository's toolchain pin, build.zig.zon, and CI. Preserve the existing pin unless an upgrade is in scope, then move to the latest compatible stable release after reading every skipped release note and compiling representative code.
Zig 0.16 still provides @cImport but deprecates it in favor of build-system translation. New code should prefer b.addTranslateC exposed through the root module's imports and consumed with @import, while existing @cImport usage can remain during scoped changes.
addTest only compiles a test artifact; it does not execute it. You must connect addRunArtifact to the test step for host-runnable targets, and foreign-target checks should be labeled compile-only unless an emulator or target system actually ran them.
Use it only as a narrowly scoped unsafe optimization with a local proof, never as a default. Correctness and security must not depend on checks that ReleaseFast or ReleaseSmall may disable, and unsafe pointer operations need proofs independent of safety-mode checks.
