Can it detect which spec I'm currently working on?

Yes, it uses automatic context detection by analyzing your file paths (e.g., src/url/) and import statements to provide the correct standard guidance.

How does it handle Zig's memory management?

The skill provides specific patterns for mapping WHATWG concepts like 'Lists' and 'Strings' to Zig's Allocator-aware types like ArrayList and slices.

What is the WHATWG Zig skill?

It is a specialized Claude Code skill designed to help developers translate WHATWG web standards into idiomatic, performant, and compliant Zig code.

Which web specifications are supported?

It provides guidance for the URL, Encoding, Console, MIME Sniff, WebIDL, Infra, Streams, Fetch, DOM, and XHR standards.

API Development

Streamlines the implementation of WHATWG standards in Zig by providing spec-compliant type mapping and algorithm guidance.

The WHATWG Specification Implementation Skill is a specialized tool for developers working on the Crane project or any Zig-based web standard implementation. It bridges the gap between formal WHATWG specifications and idiomatic Zig code by providing a structured workflow for navigating standards, mapping complex specification types to memory-safe Zig structures, and translating prose algorithms into executable code. It automatically detects the relevant standard context—such as URL, Encoding, or Streams—and ensures that implementations remain strictly compliant with official specification steps and edge cases.
