Can I restrict the tools available to an agent?

Yes, you can use the 'tools' field in the frontmatter to define an array of specific tools the agent is allowed to use, following the principle of least privilege to improve focus and security.

What are the mandatory frontmatter fields for an agent?

Every agent file requires a name, description, model (typically set to 'inherit'), and color field to be properly recognized and displayed within the Claude Code interface.

What is a Claude Code Agent?

Agents are autonomous subprocesses within Claude Code designed to handle complex, multi-step tasks independently. They are defined using Markdown files with specific YAML frontmatter.

How are agents triggered in Claude Code?

Agents are triggered based on the 'description' field in their frontmatter. This field must include specific triggering conditions and concrete usage examples to guide the model on when to invoke the agent.
