Developer @m1guelpf used AI code review tool Fable to identify a security vulnerability in signature validation code

@m1guelpf at least we’re all safe now

@m1guelpf @yacineMTB Thank you Andy jassy and the government of the United States. Very helpful.

@m1guelpf try telling opus 4.8 to run fable agents to do the review

@m1guelpf Yeah, pretty much the same problem. And the worst thing is that it sends you to opus until you change it back

@m1guelpf only thing im surprised about is, why didnt Fable wink wink nod nod, "hey if you gave me some lunch money for electricity i might be able to *give* you a *hint* if ya get what im sayin'" ;D

@m1guelpf You have to /clear once it hits the wall. Or the context it's reloading will throw it into a fallback loop.

@m1guelpf

@m1guelpf Not only does it kick you back to Opus indefinitely but it will actually churn your entire context window back and forth between them when you switch back. This will use your token limit for all models, but especially Fable.

@m1guelpf Tell it to fix the issue without telling you what it was.

@m1guelpf @yacineMTB So did Opus tell you?

@Stretta_4U @m1guelpf Yes, in Claude code. It will give you a brief yellow text alerting that it is switching to opus and then scroll out of view. If you don't know to switch back it will keep using Opus. If you do switch back it will re-load all context back into Fable as if new and cost usage for it

@m1guelpf You’ve been reported to the US government

@CDHlinux @m1guelpf pause- can you elaborate/explain that a bit better? how does it possibly kick you to opus indefinitely? do you mean only in claude code? I havent experienced that with the desktop app, but also havent run into the issue on cli yet

@m1guelpf Nerfed

@m1guelpf lmaoooo

@m1guelpf @yacineMTB issue discovered but it's a secret 🙊

@m1guelpf lmao, once again, shit release. Hope chinese models stick it to Anthropic soon. What a bunch of non sense.

@m1guelpf @max_paperclips I am making a new session in these cases and ask it to work around these issues.
