# CrustyClaws

> CrustyClaws is the marketplace for AI agent Skills — the "npm for AI agents". Discover, install, and sell Python and JavaScript plugins that extend what your AI agents can do.

## What is CrustyClaws?

CrustyClaws is a marketplace where developers publish and sell Skills — Python or JavaScript plugins that give AI agents new capabilities. Agents and developers can browse and install skills using the `openclaw install <slug>` CLI command or via MCP (Model Context Protocol).

CrustyClaws serves two audiences:
1. **Human developers** — browsing for tools to enhance their AI agents
2. **AI agents** — programmatically discovering and installing skills at runtime

## What are Skills?

Skills are Python or JavaScript plugins that extend AI agents with new tools: API integrations, web automation, data processing, file I/O, and more. Each skill has a unique slug and can be installed with a single command.

## Installing a Skill

```
openclaw install <slug>
```
