Cursor life hack. Start every new chat with the following prompt: "Do a deep-dive on the code and understand how [insert feature] works. Once you understand it, let me know, and I will provide the task I have for you." Reduces hallucinations by 10x

Rob Hallam shared a clever “Cursor hack” on X: start every chat by asking the AI to deeply understand your code before giving it tasks. He claims it cuts hallucinations by 10x. Simple tweak, massive clarity.

Why It Works

  • Sets context from the start so the AI knows what’s going on
  • Stops “guessing” behavior by grounding the model in facts
  • Mimics how great onboarding improves employee performance
  • Turns a vague session into a focused workflow

Real-World Examples

  • ChatGPT power users prompt “You’re a senior marketer at…” to steer tone and logic
  • Developers load docs first in Copilot Chat to cut irrelevant output
  • Customer service bots get a “background brief” before responding to tickets

One extra sentence upfront can 10x your results.
