Quite good as work horses? To me Luna is the work horse and Sol and Astra are prancing thoroughbreds. If I use Sol or Astra for anything other than curated reasoning and planning I will burn through my usage limits in an hour.
Same. I use Luna for research/scout/test subagents, Sol for coordinator, Terra for delegate, and Astra high for review and simplify. Even with Astra in there, it’s fresh context, and I’m consistently amazed by how far I can stretch my $20 subscription with really good results.
Why do you use Sol for the coordinator? Does it also do planning and design? Because otherwise you are cranking Sol turns on very mundane orchestration jobs.
