I've been chunking out my plans like this for months, and even maintain a port of Get-Shit-Done https://github.com/LoganDark/get-shit-done to the Jujutsu version control system because that was the best way for me to make the most of Opus.

I don't need that with Fable. I can give Fable a task of any complexity and it will spend over 8 hours in a single turn if it needs to. And then the task will be finished.

For example, Fable is far better at helping me keep that port updated with upstream's agentic pace of development. With Opus I would be spending all day working through each merge step by step. With Fable I can safely nap through it.

I don't know exactly how to communicate that difference other than that Fable just seems to make better decisions more consistently and more reliably to the point where I feel confident trusting it a lot more.
