Opus 4.5 with Elixir has been remarkably good for me. I've been writing Elixir in production since ~2018 and it continues to amaze me at the quality of code it produces.
I've been tweaking my skills to avoid nested cases, better use of with/do to control flow, good contexts, etc.
I don't have a fancy workflow per se, but I have started leaning into git workspaces more which has really been a boon with Elixir (especially in large projects where compile times can be in the many tens of seconds).
