# Creating Custom Skills 🛠
|
|
|
|
OpenClaw is designed to be easily extensible. "Skills" are the primary way to add new capabilities to your assistant.
|
|
|
|
## What is a Skill?
|
|
|
|
A skill is a directory containing a `SKILL.md` file (which provides instructions and tool definitions to the LLM) and optionally some scripts or resources.
|
|
|
|
## Step-by-Step: Your First Skill
|
|
|
|
### 1. Create the Directory
|
|
|
|
Skills live in your workspace, usually `~/.openclaw/workspace/skills/`. Create a new folder for your skill:
|
|
|
|
```bash
|
|
mkdir -p ~/.openclaw/workspace/skills/hello-world
|
|
```
|
|
|
|
### 2. Define the `SKILL.md`
|
|
|
|
Create a `SKILL.md` file in that directory. This file uses YAML frontmatter for metadata and Markdown for instructions.
|
|
|
|
```markdown
|
|
---
|
|
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 tools in the frontmatter or instruct the agent to use existing system tools (like `bash` or `browser`).
|
|
|
|
### 4. Refresh OpenClaw
|
|
|
|
Ask your agent to "refresh skills" or restart the gateway. OpenClaw will discover the new directory and index the `SKILL.md`.
|
|
|
|
## Best Practices
|
|
|
|
- **Be Concise**: Instruct the model on _what_ to do, not how to be an AI.
|
|
- **Safety First**: If your skill uses `bash`, ensure the prompts don't allow arbitrary command injection from untrusted user input.
|
|
- **Test Locally**: Use `openclaw agent --message "use my new skill"` to test.
