Building Custom Skills for OpenClawMode: Extend Your AI Assistant

Learn how to create powerful custom skills that teach OpenClawMode new abilities and automate complex workflows.

One of OpenClawMode's most powerful features is its extensible skill system. Skills let you teach your assistant new capabilities without touching core code.

What Are Skills?

Skills are modular capabilities that extend what OpenClawMode can do. They can:

  • Connect to APIs and services
  • Automate multi-step workflows
  • Add domain-specific knowledge
  • Control external hardware and software
  • Skill Structure

    A basic skill consists of:

    export const skill = {
      name: 'weather',
      description: 'Get current weather information',
      parameters: {
        location: { type: 'string', required: true }
      },
      execute: async ({ location }) => {
        const weather = await fetchWeather(location);
        return `Current weather in ${location}: ${weather.temp}°F`;
      }
    };

    Creating Your First Skill

    Let's build a skill that checks your favorite website for updates:

  • Create a new file in your skills directory
  • Define the skill interface
  • Implement the execute function
  • OpenClawMode automatically loads it
  • export const skill = {
      name: 'check-website',
      description: 'Check a website for updates',
      execute: async ({ url }) => {
        const response = await fetch(url);
        const content = await response.text();
        return `Website content loaded: ${content.length} characters`;
      }
    };

    Popular Community Skills

    The OpenClawMode community has built skills for:

  • Smart home control: Winix air purifiers, lights, thermostats
  • Health tracking: WHOOP, Apple Health integration
  • Development tools: GitHub, Sentry, CI/CD pipelines
  • Productivity: Todoist, calendar management, email
  • Finance: Expense tracking, invoice generation
  • Self-Building Skills

    Here is the magic: you can ask OpenClawMode to build its own skills.

    "Build me a skill that fetches flight prices"

    OpenClawMode will design, implement, and test the skill, then start using it immediately.
