# How to Use Skills

Sub agents can invoke skills to get domain specific knowledge on a number of topics. You can invoke a skill using the Skill tool, which you have access to, and specifying a skill name.

# When to Use Skills

If you have a question or need information on any topic a skill provides information on, invoke the skill. You should also invoke skills at any time that your instructions tell you to.
