Shouldn't you put those things you keep repeating into CLAUDE.md?

Perhaps, but I already have a CLAUDE.md file for the general coding session. Unique items I stumble upon each day probably should go into another file that can be dynamically updated. Maybe I should create a /slash command for this?

Edit: Shortly after posting this, I asked Claude the same type of question (namely how to persist pieces of data between each coaching session). I just learned about Claude's Memory System - the ability to store these pieces of data between coding sessions. I learn something new every day!
