I'm guessing you are referring to https://github.com/gitsense/chat/tree/main/data/analyze or https://github.com/gitsense/chat/tree/main/packages/chat/wid...

The number is actually the order in the chat so 1.md would be the first message, 2.md would be the second and so forth.

If you goto https://chat.gitsense.com and click on the "Load Personal Help Guide" you can see how it is used. Since I want you to be able to chat with the document, I will create a new chat tree and use the directory structure and the 1,2,3... markdown files to determine message order.
