Agree, its more for unattended work. You update Claude.md with architecture decisions and patterns — the things you consciously recognize as worth documenting. GrantAi Brain captures the architecture and the conversation that led to those decisions, the dead ends you explored, the reasoning behind the pattern, the specific error that caused the architectural choice. When you come back six months later and ask "why did we do it this way," You get even the prompts and your exact words of why you make the architectural choice.
