0. Claude, have a look at frontend project A and backend project B.
1. create a skeleton clone of frontend A, named frontend B, which is meant to be the frontend for backend project B, including the oAuth configuration
2. create the kubernetes yaml and deployment.sh, it should be available under b.mydomain.com for frontend B and run it, make sure the deployment worked by checking the page on b.mydomain.com
3. in frontend B, implement the UI for controller B1 from backend B, create the necessary routing to this component and add a link to it to the main menu, there should be a page /b1 that lists the entries, /b1/xxx to display details, /b1/xxx/edit to edit an entry and /b1/new to create one
4. in frontend B, implement the UI for controller B2 from backend B, create the necessary routing to this component and add a link to it to the main menu, etc.
etc.
All of this is done in 10 minutes. Yeah I could do all of this myself, but it would take longer.
Did you need it though? Like most projects I see being done by people with Claude Code are just their personal projects, which they wouldn't have wasted their time on in the past but now they will get pulled into the terminal thinking its only gonna take 20 mins and they end up burning 100s of subscription dollars on it. If there is no other maintainer & the project is all yours, I dont see any harm in doing it.
