a. How to Set It Up:
First, install Claude using the following command in your Terminal window:

npm i @anthropic-ai/claude-code

If Claude is already installed but it’s an older version, it won’t have the subagent feature.

to update claude, command : claude update

Launch Claude Code in your working directory, then run the command:
/agents

Press Enter, and a management screen for agents will appear, allowing you to start creating agents with specific purposes for your project.

Here, I will set it up following Claude’s recommendation.

After the setup, I have the following subagents:

I will ask Claude to help me build a website using RAG with the following prompt:

The first subagents have started working.

The setup of the RAG project has been completed.

However, I noticed that the subagent ‘production-code-reviewer (Review RAG system code)’ didn’t function after the coding was completed. It might be an issue with my prompt, so I will ask Claude to review the code for me

After the whole working process, Claude Code will deliver an excellent final product.

3. Conclusion

Through the entire setup process and practical use in a project, it’s clear how powerful and beneficial the Sub-agents feature introduced by Anthropic for Claude Code is. It enables us to have AI “teammates” with specialized skills and roles that operate independently without interfering with each other — allowing projects to be organized, easy to understand, and efficient.
