Yeah. I use it for analytics/dataviz stuff (which involves a lot of python to run spark jobs, glue different APis to get some extra column of data, making png or svg pictures,, making D3 based web sites in html and JavaScript). That all works pretty well.

I also write high performance Go server code, where it works a lot less well. It doesn't follow my rules for ptr APIs or using sync mutexes or atomic operations across a code base. It (probably slightly older version than SOTA) didn't read deep call chains accurately for refactoring. It's still worth trying but if that was my sole work it would probably not be worth it.

On the other hand for personal productivity, emacs functions and config, getting a good .mcp.json, it is also very good and generates code that partakes in the exponential growth of good code. (Unlike data viz where there is a tendency to build something and then the utility declines over time).
