It's the exact folder structure and templates I use to give AI permanent memory of my business. No more re-explaining yourself every session.

Duplicate this, fill in the blanks, and point your AI to the 00_Meta folder.

If you want to follow along with future experiments:

• Inbox Experiments
• X: @yunuserturk
• LinkedIn: Yunus Erturk

How to use:

1. Create a folder named 00_Meta in your project root.
2. Inside it, create the subfolders: Identity_Context, System_Prompts, and History_Log.
3. Copy the file contents below into their respective locations.

1. Business_Map.json

Location: 00_Meta/Identity_Context/Business_Map.json

Purpose: The single source of truth for your business structure, revenue, and projects.

My business_map.json template

2. Agent_User_Manual.md

Location: 00_Meta/System_Prompts/Agent_User_Manual.md

Purpose: Instructions for how the AI should behave and what it should read.
