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.
