We recently ran an experiment: we took the same set of coding instructions and gave them to three different AI coding agents — Cursor, Copilot, and Windsurf — to see how each would handle the task.
The results turned out to be pretty interesting, showing the strengths and weaknesses of each tool in terms of rule compliance, accuracy, and developer experience.
What’s inside the article:
- A breakdown of how each tool handles rules (types, activation, nesting, etc.)
- Testing code generation (CRUD) from the same description
- Detailed comparison: who nailed it, and who missed the mark
- Insights on when Cursor is the best choice — and when Windsurf might be a solid alternative
- Why Copilot still struggles with custom rule handling
➡️ Key takeaways:
- Cursor followed the rules most accurately and delivered the cleanest results.
- Windsurf required a bit more effort to “guide” it, but it performed reasonably well with adjustments.
- Copilot, with its current rule support, wasn’t able to produce results close to the intended structure.

I’d love to hear your thoughts:
Which of these tools have you used in your workflow?
Do you have your own coding rules or prompt strategies?
Did anything in the results surprise you?
