I have just discovered that the .cursorignore semi-workaround I thought worked, didn’t really: Adding the .git/info/exclude’d rules to .cursorignore as excludes, e.g.
.cursorignore
!.cursor/rules/local
Does put them back in Cursor’s index - so some Agents can be semi-aware of their contents and appear to follow them, but the rules are still unable to be @Mention’d and they are still not provided to the Agents.
The only way to use a rule that’s in .git/info/exclude on Mac is to manually drag-and-drop it from the file explorer into a context pill (and this of course defeats the purpose of agent-requested and glob’d prompts).
I have updated the bug report.
