depends what LLM you are using but most frontier models have seen almost every github/doc/best practices its very hard to get something like supabase/lovable type of mess unless you purposely prompt it to be bad without much inner knowledge but even then it is rectifiable with the right prompts
Everything is "rectifiable with the right prompts" if you handwave the hallucinations it makes (which yes, even frontier models do. Or I guess all companies that had major outages within the past months were using fossil models).
And it's funny this same argument can be said since Sonnet 3.7. But the issues still pop up.
