-# 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.
