That said... I jumped to a few random moments in your video and had an "oh my god" reaction because you really were not kidding when you said that you were pasting code.
I'm pretty much begging you to install and use Cursor. Whatever boost you're getting from your current workflow, you will see triple through use of their Agent/Plan/Debug modes, especially when using Opus 4.5. I promise you: it's a before electricity vs after electricity scenario. I'm actually excited for you.
A lot of folks will tell you to use Claude Code. I personally find that it doesn't make sense for the sorts of projects I work on; I would 100% start with Cursor either way.
Not busting my quota is simply not my top priority. I'm on their $200/month plan and I have it locked to a $1000/month overage limit, though the most I've ever gone through using it every day, all day is about $700. That probably sounds like a lot if you're optimizing for a $20/month token budget, but it's budgeted for. That $10-12k/year is excellent value for the silly amount of functionality that I've been able to create.
Sonnet is a really good LLM, and you can build great things with it. However, if you're using this for serious work, IMO you probably want to use the most productive tools available.
Opus 4.1 was, to be real, punishingly expensive. It made me sweat. Thank goodness that Opus 4.5 is somehow both much better and much cheaper.
Edit, I see you answered this in another response, thanks.
