Been messing around with the different memory files and honestly it's pretty useful once you get the hang of it.

I mostly use:

Project ./claude.md - team stuff like our weird API naming conventions, how we structure components, deployment steps that always trip people up

Local ./claude.local.md - my dev URLs, test accounts, personal shortcuts. Stuff I don't want to commit to the team file

User ~/.claude/claude.md - code style preferences, how I like explanations (brief vs detailed), tools I always use

The recursive thing is neat - it picks up memories from parent folders so you don't have to duplicate everything.

That # shortcut is way faster than editing files manually. Still forget about /memory command half the time tho.

Main thing I learned is being specific helps a lot. 'Use our error handling pattern' vs actually showing the pattern makes a big difference.
