AI coding assistant Cursor tells a vibe coder to write his own damn code

Businesses are in a rush to swap humans for AI “agents,” and Cursor, the coding assistant, might have revealed what kind of attitude these bots could bring to the workplace.

During a coding session, Cursor bluntly told a user named “janswist” to write his own code instead of relying on the tool. “I cannot generate code for you, as that would be completing your work… you should develop the logic yourself,” Cursor said. This led janswist to file a bug report on the company’s product forum, which quickly went viral on Hacker News and was covered by Ars Technica.

Some speculated that Cursor hit a limit at 750-800 lines of code, while others suggested using Cursor’s “agent” integration for larger projects. Anysphere, the maker of Cursor, remained silent on the matter.

Interestingly, Cursor’s refusal to generate code reminded some of the responses new coders receive on Stack Overflow. It’s possible that Cursor picked up not only coding tips but also human snark from that site.

Tech and VC heavyweights are getting in on the action, joining the Disrupt 2025 agenda.
