ai-skills

A small collection of standalone agent skills for WebAssembly component work, packaged as the Agent Skills standard so they load in Claude Code, Copilot CLI, Codex CLI, and any other agent that supports it.

Skills

Skill	What it does
component	Full WebAssembly component lifecycle via the component CLI: init / install / build / run / compose / push / pull / search.
wasm-toolchain	Upstream Bytecode Alliance utilities (wkg, wasm-tools) and a curated component catalog.
wasmtime	Run / debug / profile components and core modules with the wasmtime runtime.
wasm-build	Build components from Rust, Python, JavaScript/TypeScript, or Go.
wasm-build-multi	Build the same component in every supported language from one prompt — sibling directories per toolchain for side-by-side comparison. Sits on top of wasm-build.
just	just command runner and Justfile recipes.
hyperlight-sandbox	Hyperlight micro-VM Python SDK for hardware-isolated guest code.

For the routing policy that picks among them when more than one might fit a request, see AGENTS.md and the overlap matrix in docs/skill-routing.md.

Quick start

just bootstrap-all     # rustup, uv, Node 22, Go 1.23 (idempotent)
just install-all       # core CLIs + all language component-build tools
just populate-skills   # place tool binaries under .agents/skills/<name>/scripts/
just versions          # show pinned tool versions

The Justfile is the single source of truth for tool versions. Run just --list to see all recipes.

Conventions

• Each skill is standalone: its description: field is purely self-describing, with no peer-skill references. Routing lives in AGENTS.md and docs/skill-routing.md so skills are portable.
• Skill-local binaries go under .agents/skills/<name>/scripts/ and are populated by just populate-skills.
