This seems very nice! Only downside is that the repo hadn't any updates in two weeks and they seem to have shifted development to 'Gitclaw' which is basically the same just with the shitty claw name - that gives one immediately security nightmare notions. For professional users not a good branding in my opinion.
We do something similar at work, called metadev. It sits above all repos and git submodules othe repos in, and works with multiple changes with multiple sessions with worktrees, and stores long term knowledge in /learnings. Our trick has been to put domain specific prompts in the submodules, and developer process in metadev. Because of the way Claude hierarchically includes context, the top repo is not polluted with too much domain specifics.
Love to discuss and see how we can make this more standard
