I got Claude to make a tool to record all of the prompts in and all of the responses out. but not the actual file changes.

https://github.com/lawless-m/Devolver

it uses hooks to export the session

https://github.com/lawless-m/Devolver/blob/master/HOOKS.md

and then parses the session logs and dumps them out

https://github.com/lawless-m/Devolver/blob/master/JSONL_FORM...

I then have it go to a central location because I use multiple machines and it creates a website so I can see what I've been working on.

Reading these figures now, I think it counts its own prompts, you know it talks to itself. There's no way I've typed ten thousand prompts on that project
