Ask claude to do it end to end, then write a solution that fits your needs from it's experience with you driving it.

I did exactly this - probably the single most valuable piece of software I've "written". It's the backbone of every piece of code coming out of any agent under my control (via MCP toolset).

That’s like half a day to get to sensible useful defaults that everybody needs. Any chance you’d be up to push what you got to git?
