How does Claude know when to use a subagent?

Claude reads the 'description' field in the subagent's YAML frontmatter to decide when to delegate tasks based on the user's current activity or explicit requests.

Can I limit what tools a subagent can access?

Yes, you can use the 'tools' field in the YAML frontmatter to specify allowed tools like Read, Write, or restricted Bash commands, following the principle of least privilege.
