Really great for quickly building features but you have to be careful about how much context you provide i.e. spoonfeed it exactly the methods, classes, files it needs to do whatever you're asking for (especially in a large codebase). And when it seems to get confused, reset history to free up the context window.

That being said there are definite areas where it shines (cookie cutter UI) and places where it struggles. It's really good at one-shotting React components and Flutter widgets but it tends to struggle with complicated business logic like sync engines. More straightforward backend stuff like CRUD endpoints are definitely doable.
