This afternoon, my cursor automatically updated. Previously, I relied on a codebase feature that automatically located the precise lines of code needing modification within my projects.
However, after the update, the agent functionality, in conjunction with sonnet3.7, is attempting to modify my YAML files by adding CSS – something that never happened before.
Furthermore, the current DeepSeek R1 lacks chain-of-thought reasoning; it’s soulless, and its responses lack depth. And all this happened within a single day – it was working perfectly this morning.
