For an entire project? Yes I agree. For a feature or a submodule? I think when you work with claude to develop a plan, it's generally pretty good.

I guess my question stems from being rigid how a design doc should be defined, argued over, and then executed by humans. I think some of the details simply don't matter, and if they do, they often can be changed relatively quickly in order to adhere to the new requirement.

Try the claude-mem plugin.
