Claude Desktop and Fable 5.1 safeguards are still terrible, RT shader work in UnrealEngine flagged as [cybersecurity] work, and dropped to Opus 4.8

I just re-subscribed today to try Fable 5.1, but it's absolutely terrible, I haven't run into this at all with Astra, and funnily enough I had 0 issues working with Fable 5.1 in Cursor on this same task, so it's only Anthropics own safeguard implementation that sucks.
