The First Thing I Set Up Before Any AI Coding Agent A developer recommends mapping a dedicated folder to its own drive letter before running any AI coding agent, so that destructive commands like `rm -rf` stay confined to an isolated workspace rather than the user's home folder. The setup involves creating an agent workspace folder, mapping it to a drive letter, and pointing the agent at that drive. Before I let any AI coding agent touch my machine, I do one thing: give it its own drive letter. The 5-minute setup 1. Create a folder for the agent workspace 2. Map it to a drive letter 3. Point the agent at that drive 4. Start working Tools - Local folder mapping: subst.scsoi.com - WebDAV/cloud mapping: drive.scsoi.com Why first? Because the first time an agent runs rm -rf , you want it to be confined to its own drive, not your home folder. Set up the sandbox before you set up the agent.
