 ## Why
 
-Claude Code agents forget everything when a session ends. The usual fix — calling `mem_save` manually — has three failure points: the agent must decide what to save, remember to call it, and remember to call `mem_context` at the next start. Most sessions end without any memory saved.
+Claude Code agents forget everything when a session ends. Manual memory tools have three failure points: the agent must decide what to save, remember to save it, and remember to load it at the next start. Most sessions end without any memory saved.
 
 `mem` uses Claude Code hooks that fire **reliably at session boundaries**. The infrastructure captures memory. The agent never has to think about it.
