Summary
Claude Code can run on your computer and act as a personal AI assistant that reads and edits your local files.
By pairing it with Obsidian and simple markdown rules, you can assign tasks, spin up sub-agents, and keep shared context in files so work stays organized.
New features like Output Styles let you change Claude’s role from coder to researcher or creative helper.

Claude Code is one of the first truly agentic AI systems available to the public, capable of acting as a personal assistant that lives on your computer and works with your local files. You can do a lot more with it than just write code.

Sub-agents research and plan; the parent agent executes. Think of sub-agents as specialist researchers. Their only job is to gather information and return a detailed plan. The parent agent, which maintains the full project context, is the only one that should ever write or edit files. And since this tutorial is all about how to use Claude Code as a personal assistant, NOT a coding assistant, you can apply the same logic to using sub-agents as your “sub-assistants”, not your “personal chief of staff” as we described it at the beginning.
