Building Your First OpenClaw Agent: A Step-by-Step Guide


Getting started with autonomous agents can feel overwhelming. There are frameworks, APIs, prompts, and orchestration to think about. But it doesn’t have to be complicated.

What is OpenClaw?

OpenClaw is an open-source framework for building AI-native applications. Think of it as the infrastructure layer for the agent economy — the plumbing that lets you focus on what your agent does, not how it runs.

Prerequisites

Before we start, you’ll need:

  • Node.js 18+ installed
  • An OpenAI API key (or alternative)
  • Basic familiarity with JavaScript/TypeScript

Installation

npm install -g openclaw
openclaw init my-first-agent
cd my-first-agent
npm install

Your First Agent

OpenClaw uses a simple configuration-based approach. Here’s a basic agent that can answer questions:

// agent.config.ts
export default {
  name: 'helper',
  model: 'gpt-4',
  systemPrompt: `You are a helpful assistant. Be concise and accurate.`,
  tools: ['web_search', 'calculator'],
};

Adding Capabilities

The real power comes from tools. OpenClaw includes built-in tools for:

  • Web browsing
  • File operations
  • API calls
  • Code execution

You can also write custom tools:

export const tools = {
  getWeather: async (location: string) => {
    // Your weather API call here
  },
};

Deployment

When you’re ready to deploy:

openclaw deploy

Your agent is now running and accessible via API, webhook, or scheduled tasks.

Next Steps

Building agents is still early days. The tools will get better, but the fundamentals — clear goals, good prompts, reliable tools — will stay the same.
