I've found it to be great for planning code changes (or new projects). I use the superpowers plug-in which I think guides the planning.

Then I switch models (to luna) before implementation. I find this combo nearly always does what I want.

I also use a skill called ponytail, its goal is to keep things terse and edits small. It may have contributed to the successes above.

I like that skills are easy to try out, too.

I stopped using superpowers because it wanted to turn every tiny bug fix into a $37MM DOD project. I got effective results but it took ages. I may try again - I need to find a good way to run different profiles in my harness so I can easily shut it off. The default planning workflow in OMP is pretty good though.

I agree Luna is great for task execution, either as a sub-agent with Sol planning and coordinating or if the task is well defined and straightforward, but there are lots of models now that you can say that about.

I have the same setup you have, love it!
