 Checks if the User has permission clearance, optionally on a resource
 
 ```liquid
-{{ User | has_permission:"EditContent",Model.ContentItem }}

 ```
 
 #### User is_in_role filter
 
 Checks if the user is in role
 
 ```liquid
-{{ User | is_in_role:"Administrator" }}
+{{ User | is_in_role: "Administrator" }}
 ```
 
 #### User has_claim filter
 
 Checks if the user has a claim of the specified type
 
 ```liquid
-{{ User | has_claim:"email_verified","true" }}
-{{ User | has_claim:"Permission","ManageSettings" }}
+{{ User | has_claim: "email_verified", "true" }}
 ```
 
+!!! warning
+    To avoid false negatives for Administrator users, ensure you use the `has_permission` filter instead of `has_claim` when checking if a user has a permission. This ensures accurate permission evaluation, especially for administrators who may not have explicit claims but still possess full access rights.
