What's Wrong?

I read about the new memory feature in claude code and I see it making updates to it's internal memory files.

Problem is it does so without knowing nor caring that it's duplicating info already in CLAUDE.md!

Waste of context and token $.

I've turned it off.

$ grep autoMemory ~/.claude/settings.json
  "autoMemoryEnabled": false

What Should Happen?

It shouldn't duplicate info already in CLAUDE.md or other .md file that it reads.

Use it for a while and notice when it updates it's memory, some of those updates will be duplicating info it already has in CLAUDE.md
