Frequently asked questions

Why does Cursor introduce async timing bugs?+

Cursor may introduce async timing bugs due to its autocomplete and multi-file editing features, which can inadvertently alter the order of async operations. Reviewing the execution order is crucial.

How can I ensure Cursor follows my project rules?+

Ensure your .cursorrules file is up-to-date and clearly defines the order and synchronization of async operations. Cursor reads this file to guide its actions.

What are common signs of async timing issues?+

Common signs include inconsistent state updates, incorrect cache data, and unexpected database results. These often stem from operations executing out of order.

How do I maintain context in large projects?+

Regularly save and review your project's .cursorrules file, and periodically restart Cursor sessions to refresh its context awareness.

Can Cursor automatically fix async issues?+

Cursor can suggest fixes based on its understanding of your code, but manual verification and testing are recommended to ensure correctness.
