zig-best-practices SKILL.md skillA
zig-best-practices from aiskillstore/marketplace is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when reading or writing Zig files (.zig, build.zig, build.zig.zon).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Zig Best Practices
Follows type-first, functional, and error handling patterns from CLAUDE.md. This skill covers Zig-specific idioms only.
## Type System Patterns
**Tagged unions for mutually exclusive states** — prevents invalid combinations that a struct with multiple nullable fields would allow:
```zig
const RequestState = union(enum) {
idle,
loading,
success: []const u8,
failure: anyerror,
};
```
**Explicit error sets** — documents exactly what can fail; `anyerror` hides failure modes:
```zig
const ParseError = error{ InvalidSyntax, UnexpectedToken, EndOfInput };
fn parse(input: []const u8) ParseError!Ast { ... }
```
**Distinct types for domain IDs** — compiler prevents mixing up different ID types:
```zig
const UserId = enum(u64) { _ };
const OrderId = enum(u64) { _ };
```
**Comptime validation** — catch invalid configurations at compile time, not runtime:
```zig
fn Buffer(comptime size: usize) type {
if (size == 0) @compileError("buffer size must be greater than 0");
return struct { data: [size]u8 = undefined, len: usize = 0 };
}
```

How to install
mdr add aiskillstore/marketplace/zig-best-practices@sha256:b44bbabb0c6618c7The line at the top of this page pins the label git:20260705.e9e4712, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
