  1. Claude Fable is relentlessly proactive

    After two days of experience with Claude Fable 5 I think the best way to describe it is relentlessly proactive. It knows a whole lot of tricks and it will deploy pretty much any of them to get to its goal. I'll illustrate this with an example. I was hacking on Datasette Agent today when I noticed a glitch…

You have to quickly stop doing things that aren’t cost-effective, to avoid “throwing good money […]
