Right out the toaster. Reliable, with some real depth.
Summary
The article describes a developer's experience during a hackathon where they attempted to use AI coding assistants (Cursor and Claude) to integrate a solar generation data API. Despite what seemed like a simple task, both AI tools failed to handle a subtle string formatting bug, taking two days to debug. The article reveals how AI coding assistants can struggle with seemingly trivial issues and provides insights into their limitations in real-world development scenarios.
