vendor-submodules - SKILL.md Agent Skill

name: vendor-submodules description: Locate and sync the vendored reference specs and runtimes under vendor/ (Wasm, WASI P3, and Component Model specs; wasm-tools, wasmtime sources). Use when you need to read a Wasm/WASI/CM spec or wasmtime/wasm-tools source, or when vendor/ submodules are missing and need initializing.

The Wasm and WASI (p3) specifications

There are external references in the module for convenience:

vendor/wasm/ - WebAssembly/spec
vendor/wasi/ - WebAssembly/WASI
vendor/component-model/ - WebAssembly/component-model (CM spec)
- Canonical built-ins: vendor/component-model/design/mvp/CanonicalABI.md
- Concurrency (async, streams, futures): vendor/component-model/design/mvp/Concurrency.md
- Explainer: vendor/component-model/design/mvp/Explainer.md
vendor/wasmtime/ - a Wasm runtime with WASI P3 support
vendor/wasm-tools/ - a Wasm toolchain, where the Wado compiler relies on

Use git submodule update --init to have the vendor modules.

Syncing Vendor Submodules

Run the following to sync all vendor submodules:

mise run sync-vendor

This syncs vendor/wasmtime to the exact version in Cargo.lock (required for WASI P3 compatibility), and updates other vendor submodules (vendor/wasm, vendor/wasi, vendor/wasm-tools, vendor/component-model) to their latest remote HEAD.
