I have not yet used Claude Code personally, but I believe that Cursor and Windsurf both optimize token usage by limiting how much of your code each prompt analyzes.

With Claude Code, all bets are off there. You get a better understanding of your code in each prompt, and the bill can rack up, what, 50x faster?

If I got really stuck on a problem involving many lines of code, I could see myself spinning up Claude Code for that one issue, then quickly going back to Windsurf.
