Thanks! With Spec-Kit and Claude Sonnet 4.5, it wanted to design the whole prod-ready CLI up front. It was hard, if not impossible, to try to scope it to just a single feature or POC. This is what I struggled with most.

Were I to try again, I'd do a lot more manual spec writing or even template rewrites. I expected it to work more-or-less out-of-the-box. Maybe it would've for a standard web app using a popular framework.

It was also difficult to know where one "spec" ended and the next began; should I iterate on the existing one or create a new spec? This might be a solved problem in other SDD frameworks besides Spec-Kit, or else I'm just over thinking it!
