## Summary

Claude Code lets users create a simple AI agent to sort files by type or date without coding. The author recommends starting with a ‘File Organizer’ to practice core agent skills: reading files, making decisions, moving files, and keeping records. Users create a practice folder, ask Claude Code to sort files into categories (documents, spreadsheets, images, others), and review the list before execution. The agent then logs actions in a markdown file for transparency.

The tutorial avoids deletion risks by default and suggests refining the agent over time—adding rules like moving invoices to a dedicated folder or archiving old files. The author warns to back up important files and verify changes manually before applying it to real folders. The next article will cover writing an agent’s manual, *CLAUDE.md*, to automate tasks with a single command.

## Key points

- Claude Code’s file organizer agent sorts files by type or date in a practice folder first
- Users must approve each move and add ‘do not delete’ and ‘show list before acting’ rules
- Agent logs actions in a markdown file and can be expanded with custom rules like invoices or archives

## Why it matters

This hands-on guide lowers the barrier to building AI agents for repetitive tasks like file management, appealing to non-technical users. It demonstrates how to safely delegate simple workflows while documenting actions—skills transferable to more complex agents.
