How do I create a new subagent in Claude Code?

You can use the /agents command to open an interactive interface or manually create a markdown file in the .claude/agents/ directory.

How does Claude know which subagent to use?

Claude uses the description field in the subagent's configuration to automatically route tasks to the most appropriate agent based on the current context.

Why use XML tags for subagent instructions?

XML tags provide a clear, semantic structure that Claude parses more efficiently than standard markdown, leading to better instruction following and token usage.

What is a Claude Code subagent?

A subagent is a specialized instance of Claude that runs in an isolated context with a focused role and specific tool access to perform tasks autonomously.

Can subagents ask the user questions?

No, subagents are black boxes that cannot use interactive tools like AskUserQuestion. They perform their task and return a final output to the main conversation.

Productivity & Workflow

Streamlines the creation and orchestration of specialized Claude subagents for autonomous, multi-agent developer workflows.

This skill provides a comprehensive framework for building and managing a multi-agent ecosystem within Claude Code. It guides users through creating specialized subagents with focused roles, configuring least-privilege tool access, and implementing high-efficiency XML-based system prompts. By leveraging the Task tool and diverse model selection (Sonnet, Opus, Haiku), developers can delegate complex research, auditing, and generation tasks to isolated agents that operate autonomously, significantly increasing productivity by handling background operations without constant user intervention.
