I already was doing something similar on a regular basis.

I have many "folders"... each with a README.md, a scripts folder, and an optional GUIDE.md.

Whenever I arrive at some code that I know can be reused easily (for example: clerk.dev integration hat spans frontend and backend both), I used to create a "folder" of the same.

When needed, I used to just copy-paste all the folder content using my https://www.npmjs.com/package/merge-to-md package.

This has worked flawlessly well for me uptil now.

Glad we are bringing such capability natively into these coding agents.
