Cursor rules stopped working

[nachos]

Describe the Bug

The models (Gemini 2.5 Pro, Sonnet 4, maybe others), ignore the cursor rules completely.

Steps to Reproduce

Add a fun rule like “Speak like a pirate” or “Add a joke after your response.”
Make a request

Expected Behavior

Rule applied and we get responses like “Yarr” or they would end with a bad joke like “Why don’t scientists trust atoms? Because they make up everything!?”

(Depending on the rule)

Doesn’t seem to fail on Mac

Operating System

Windows 10/11

Additional Information

I tested “before” and “after” update, after it was reported to me at my work

Does this stop you from using Cursor

No - I reverted to version 1.2.x to mitigate the issue

Hey, could you let me know whether this happens in user rules, .cursorrules, or project rules?

[zeged]

At the least user rules aren’t working.
And also checkpoints afaik.

[nachos]

I tested gradually (First only user rules, then added project rules, and finally .cursorrules)

User rules (Pirate tongue)

Project rules work for me. (.cursor\rules folder) (Parseltongue)

.cursorrules also works (‘Shalalalalala’)

Same, never worked.

Could you try hitting “check for updates” and upgrading to 1.3.6? It should fix this - sometimes we’ve found rules not being respected in earlier versions. Apologies

[nachos]

I confirm this works. Thank you for the quick turnaround!
