Oh that's wild, I did suspect that but didn't know it outright. Mind-blowing Google would release that kind of thing, I had wondered why it sucked so much haha. Okay so what is a good representation of the current state of coding agents? Which one should I try that does a better job at code modifications?

Claude code is the strongest atm, but roocode or cline (vscode extensions) can also work well. Roo with gpt5-mini (so cheap, pretty fast) does diff based edits w/ good coordination over a task, and finishes most tasks that I tried. It even calls them "surgical diffs" :D

claude code (with max subscription), cursor-agent (with usage based pricing)
