Not my experience at all.

It fails to be pro-active. "Why didn't you run the tests you created?"

I want it to tell me if the implementation is working.

Feels lazy. And it hallucinates solutions frequently.

It pales in comparison to CC/Opus.

I feel like this is exactly the use case for things like Hooks and Skills. Which, if you don't want to write them yourself, I get it. But I do think we can get the tool to do it; sounds like you want it doing that a little more actively/out-of-the-box?
