The official WASM skill registry for ZeroClaw — browse, install, and publish tool packages for your autonomous agent.
ZeroMarket is a registry where developers can publish WASM skill packages — compiled WebAssembly tools that ZeroClaw agents can install and use. Skills follow a simple stdin/stdout protocol, so any language that compiles to WebAssembly works: Rust, TypeScript (Javy), Go (TinyGo), Python (componentize-py), and more.
# Install a skill in one command
zeroclaw skill install zeroclaw/weather-lookup
# The agent can use it immediately
zeroclaw agent -m "What's the weather in Hanoi?"- Framework — Next.js 15 (App Router)
- Styling — Tailwind CSS v4
- Auth — NextAuth v5 (GitHub OAuth)
- Database — PostgreSQL + Drizzle ORM
- Package Manager — pnpm
- Node.js 18+

Every ZeroMarket skill is a WASM binary that reads JSON from stdin and writes JSON to stdout:
// stdin → args from LLM
{"city": "Hanoi"}
// stdout → result
{"success": true, "output": "Hanoi: 28.5°C, Partly Cloudy"}

# List installed skills
zeroclaw skill listThe registry exposes a REST API consumed by zeroclaw skill install:
GET /api/v1/packages/:namespace/:name
→ { name, version, description, tools: [{ name, wasm_url, manifest_url }] }
