Anyone else find that Fable 5.1 is making significantly more assumptions based on vibes than Fable 5? I’m not sure what’s going on but even on higher effort levels (xhigh & max) I find myself having to check it on a lot of the stuff it says when I ask it a question about performance, bugs etc. It’s like it doesn’t actually check anything unless explicitly require it to check before answering questions. Even when I didn’t ask anything and it’s just keeping me up to date on running code, it makes assertions based on nothing. I have reasonably good context hygiene (minimal skills, new sessions for different tasks, compact >30% etc) and even then it just doesn’t seem to produce answers and make assertions based on assumptions rather than evidence. Is this happening to anyone else? submitted by /u/ArcticMooss
