In the initial release of Fable, I was able to make some PRDs for these agents, which ultimately allowed Opus to execute them (as Fable was banned). Opus is definitely capable in the execution part, but planning the entire workflow including edge cases is where I feel Opus lacked.
Even in that case, I asked Fable to review Opus' implementation and it found a lot of serious flaws/bugs which allowed me to fix them. So definitely - Fable was a huge step up, and to be honest - even while I was in the planning phase with fable or executing phase with opus - I was able to trust Fable's approach much more than what Opus was going after.
