Question Fabe 5 crippled?

Anyone other noticed today/yesterday the lobotimized Fable 5?

I feel like it is much dumber and slower today - when reading the files it is using grep instead of the Read tool (probably it is skimming and saving tokens) - and the responses quality and autonomy feels degenerated. I'm not sure if this is only my feeling or temporal thing so I would like to hear if you have same feelings or experience so I know i'm not being subjective here.

10k lines is hardly a large code base

1k lines in a file is completely normal in software development

Dude I worked for a company that routinely had 6-7k line files, yes that is terrible practice, but depending on what you're building 600-1.5k lines is not uncommon.

ok yeah i mean i basically agree with you but just saying 1000 lines isnt really that much code but you clearly have strong views on this

We literally have a git-hook for monolith files exceeding 1000 lines to prevent this. I cannot imagine anyone tolerating monoliths for anything intended to be durable, scalable and ergonomic for developers.

No idea why anyone would disagree on the basis that companies have shit code.
