 ### Included AI skills
 
 This project [includes](./resources/boost/skills) three AI skills focused on managing the `.gitattributes` file for a package:
-- validating: check whether the current `.gitattributes` content matches the expected export-ignore rules.
-- creating: generate a `.gitattributes` file when it is missing.
-- updating: reconcile an existing `.gitattributes` file with expected export-ignore rules.
+- __validate__: check whether the current `.gitattributes` content matches the expected export-ignore rules.
+- __create__: generate a `.gitattributes` file when it is missing.
+- __update__: reconcile an existing `.gitattributes` file with expected export-ignore rules.
