Hey, thanks for the report. To help with the investigation, please share:

  • What exactly happens when you ask Cheetah to fetch rules? Do you see an error message, or does it just not respond?
  • A screenshot or chat transcript showing Cheetah’s response when you try this feature
  • Which Cursor version this last worked in (if you remember)

In the meantime, you can manually reference rules using @Rules in chat, or set rules to “Always” or “Auto Attached” in .cursor/rules so they’re included automatically.

Oh just to add context.

The model is aware of the fetch_rules tool because i have a user_rule that incentivate the model to use this tool more, if I would remove that rule of course the model would be confused since it doesn’t know what tool to use to “fetch rules”

Confirm, the models can not fetch rules since a few days.

Prompt: is the fetch_rules tool available to you at the moment?

Reply: No — that tool isn’t available in my current toolset. I can read <file path here> directly instead if you’d like.

This is really annoying and i dont want to load all the rules per default it will bloat my context and burn tokens/credits! Please fix with high prio!
