It's ultrathink one word, not ultra-think. (See below).

I use Claude Code with Opus, and had same experience - was pushing it hard to implement complex test, and it gave me an empty test function with test plan inside in a comment (lol).

I do want to try Gemini 2.5 Pro, but I don't know a tool which would make experience compatible to Claude Code. Would it make sense to use with Cursor? Do they try to limit context?
