I love this! I have a similar automation for moving a feature through ideation/requirements/technical design, but I usually dump the result into Cursor for last mile and to save on inference. Seeing the cost analysis is eye opening.
There’s probably also some upside to running the same model multiple times. I find Sonnet will sometimes fail, I’ll roll back and try again with same prompt but clean context, and it will succeed.
re: cost analysis
There's something cooked about Windsurf/Cursors' go-to-market pricing - there's no way they are turning a profit at $50/month. $50/month gets you a happy meal experience. If you want more power, you gotta ditch snacking at McDonald’s.
In the future, companies should budget $100 USD to $500 USD per day, per dev, on tokens as the new normal for business, which is circa $25k USD (low end) to $50k USD (likely) to $127k USD (highest) per year.
