create-subagent

Create specialized AI agents by defining subagent templates with YAML frontmatter, system prompts, and tool configurations. Specify the agent's name, description, assigned Claude model, and restricted tool access to focus expertise on domain-specific tasks like code review, testing, or security auditing.

Yes, you can assign specific Claude models—Haiku, Sonnet, or Opus—to each subagent based on task complexity and performance requirements. Model selection lets you optimize for speed, cost, or reasoning depth for each specialized agent.

Agent orchestration works by defining specialized subagents with focused expertise, then allowing Claude to autonomously invoke the most relevant agent based on your task. Claude delegates to the right specialist, streamlining complex workflows without manual routing.

Restrict tool access per subagent through configuration settings in the YAML frontmatter and system prompt sections. Limiting tools to domain-relevant ones prevents misuse, reduces token consumption, and ensures each agent stays focused on its specialized purpose.

No prerequisites required. This Skill provides templates with required fields (name, description) and optional model/tool settings, enabling you to build custom agents regardless of prior agent-building experience. Best-practice descriptions guide implementation.

Create a subagent when you need sustained expertise in a narrow domain—like test execution, security review, or database optimization—where delegation improves quality and saves time. Subagents excel when tasks recur or require consistent tool restrictions.
