What is a Claude Code agent?

Agents are autonomous task handlers that extend Claude Code's capabilities. They run as independent subprocesses with their own context to perform multi-step operations without constant user intervention.

Can I restrict the tools an agent has access to?

Yes, the Agent Creator helps you specify tool restrictions in the agent's YAML frontmatter, following the principle of least privilege to ensure the agent only uses necessary capabilities.

How do I trigger the Agent Creator skill?

The skill is automatically activated when you use phrases like 'create an agent', 'new agent', or 'build an agent', or when you begin editing agent markdown files.

When should I create an Agent versus a Skill?

Create an Agent for autonomous, multi-step execution invoked via the Task tool. Create a Skill when you want domain-specific knowledge or procedural guidance to load automatically during a conversation.

What models are supported for Claude Code agents?

Agents can use Sonnet, Haiku, or Opus models, or they can 'inherit' the model currently being used by the parent Claude Code session.

Streamlines the creation and management of autonomous task-handling agents for Claude Code plugins.

The Agent Creator skill provides a comprehensive framework for developing specialized, autonomous agents within the Claude Code ecosystem. It guides users through every stage of the development lifecycle—from defining purpose and trigger conditions to writing YAML frontmatter and structuring complex instruction workflows—ensuring that new agents are robust, specialized, and properly integrated into plugin marketplaces. By following standardized patterns and best practices, this skill enables the rapid deployment of domain-specific agents that can handle multi-step tasks independently.
