SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build Wasm runtimes, validators, parsers, and compiler frontends that conform to the official WebAssembly specifications, reducing drift and enabling reliable Wasm-first development.

Core Features & Use Cases

  • Semantic alignment with Core spec and wasm3 notes for embedding behavior.
  • Plans for feature gates, conformance workflows, and proof-guided optimizations.
  • Use cases include implementing Wasm runtimes, validators, compilers, and interop layers.

Quick Start

Initialize a baseline Wasm feature policy and consult the spec map to freeze ABI conventions and data layouts, then begin implementing the baseline in accordance with the wasm-first principles.

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

FAQPage Schema
How do I build a WebAssembly runtime that conforms to the official spec?▼

Spec-aligned Wasm runtimes require semantic alignment with the Core spec and wasm3 notes for embedding behavior. You can build runtimes, validators, parsers, and compiler frontends while reducing drift and enabling reliable Wasm-first development.

How do I implement deterministic host boundaries for WebAssembly interop?▼

Spec-aligned Wasm interop requires mapping high-level language constructs to Wasm and defining data layouts with ABI contracts. This approach supports JS/browser/GPU interop layers and deterministic host boundaries across the runtime.

What is the best way to manage feature gates for a Wasm validator?▼

Feature gate governance for Wasm validators requires initializing a baseline feature policy and consulting the spec map to freeze ABI conventions. This enables robust feature flag governance across wasm tooling and conformance workflows.

Does this approach support proof-guided optimization strategies for Wasm compilers?▼

Yes, proof-guided optimization strategies are supported alongside conformance workflows and feature gates. This approach maintains semantic alignment with the Core spec and wasm3 notes to reduce drift in Wasm compiler frontends.

When do I need to freeze ABI conventions and data layouts in a Wasm parser?▼

Freeze ABI conventions and data layouts during the initial baseline setup of a Wasm parser. Initialize a baseline Wasm feature policy, consult the spec map, and establish these contracts before beginning implementation to ensure spec alignment.
