DEBE_DE rule is scheduled to be removed. Reason is that correct and incorrect use forms are virtually undetectable even with the semantic context because is the author who decides the sense given. In fact, for the examples embedded in the rule both correct and incorrect forms are correct depending on the sense the author give.
You can check it in Museo de los horrores from CVC.
Same thing happens with PRONOMBRES_EXCLAMATIVOS_E_INTERROGATIVOS rulegroup. It’s tempting even using exlamation or question marks to locate mistakes but if you think twice you have a probability of 50% hit, or less if the writer is seasoned.
However I encourage you to submit more rules. Please use the Rule Editor in the community site to create rules and post them here.
Best regards,
