Youtube is filled with content from people who've used Claude Code to build this. Some use Claude Code to run it. A cron job initiates claude code to scan all signals and create a todo-list, action it, etc.

Search for "personal ai infra" or "claude code life os"

Might be a good starting point to get some inspiration.

[EDIT] PS: I just saw your profile and seems like you are a co-founder of a company that does exactly this? ¯\_(ツ)_/¯
