Creating Skills

Skills teach the agent how and when to use tools. Each skill is a directory containing a SKILL.md file with YAML frontmatter and markdown instructions.

For how skills are loaded and prioritized, see Skills.

Create your first skill

1. Create the skill directory

   Skills live in your workspace. Create a new folder:

   mkdir -p ~/.openclaw/workspace/skills/hello-world
   

2. Write SKILL.md

   Create SKILL.md inside that directory. The frontmatter defines metadata, and the markdown body contains instructions for the agent.

   ---
   name: hello_world
   description: A simple skill that says hello.
   ---
   
   # Hello World Skill
   
   When the user asks for a greeting, use the `echo` tool to say
   "Hello from your custom skill!".
   

3. Add tools (optional)

   You can define custom tool schemas in the frontmatter or instruct the agent to use existing system tools (like exec or browser). Skills can also ship inside plugins alongside the tools they document.

4. Load the skill

   Start a new session so OpenClaw picks up the skill:

   # From chat
   /new
   
   # Or restart the gateway
   openclaw gateway restart
   

   Verify the skill loaded:

   openclaw skills list
   

5. Test it

   Send a message that should trigger the skill:

   openclaw agent --message "give me a greeting"
   

   Or just chat with the agent and ask for a greeting.

Skill metadata reference

The YAML frontmatter supports these fields:

Best practices

• Be concise — instruct the model on what to do, not how to be an AI
• Safety first — if your skill uses exec, ensure prompts don't allow arbitrary command injection from untrusted input
• Test locally — use openclaw agent --message "..." to test before sharing
• Use ClawHub — browse and contribute skills at ClawHub
