Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. I can see in the screenshot that your Conciseness rule isn’t showing up in Active Rules. Only the Distribution test rule (added by Cursor) is visible.

This looks like a known issue. Rules with alwaysApply: true don’t load correctly when using Auto mode or the Composer 1 model.

Workaround for now: try switching to a specific model instead of Auto, like Claude Sonnet, GPT 5.2-Codex, or Gemini 3 Flash. With those, the rules should apply correctly.

The team is aware of the issue. There’s no ETA yet, but your report helps us prioritize it.

I am rephrasing my comment that was hidden: I think it’s unfair that users of the Auto mode are unable to use the rules, and the suggested workaround requires paying extra.

ran into something similar when testing rules recently. a few things i noticed:

  • rules created through the UI seemed to stick better than ones manually dropped as .mdc files
  • if the frontmatter format is slightly off (missing newline after closing ---, wrong field names) cursor silently ignores the file with no error
  • restarting cursor sometimes helps, sometimes doesn’t

what version are you on? and are you creating through the UI or manually?
