My trick for using Opus is using it exclusively as a subagent managed by Fable.

"Use Opus subagents for this work where possible" is all it takes generally.

In my experience Astra/Sol are both quite good as workhorses, but not at Fable's level. I use them every day very successfully and I'm very picky.

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.

what harness?

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.

I used to do this but recently I switched to having Fable 5.1 spawn forks of itself rather than Opus subagents. Yes it's more expensive but you don't pay for reads that already happened pre-fork, and you end up doing less rework since Fable agents are just much smarter.

That makes sense. I'm also using $200/mo Claude subscriptions, so I want to take advantage of the other 50% by using Opus.
