 ```json
-"[yara]": {
-  "editor.tabSize": 4,
-  "editor.insertSpaces": false,
-  "editor.detectIndentation": false,
-  "editor.formatOnSave": true
-}
+"YARA.ruleNameValidation": "^APT_.+$",
+"YARA.metadataValidation": [
+  {
+    "identifier": "author",
+    "required": true,
+    "type": "string"
+  },

+### `YARA.ruleNameValidation`
+
+Type: `string`
+Default: `""` (no validation)
+
+A regular expression that rule names must conform to. If a rule name does not match this pattern, a warning will be 
+generated.
+
+### `YARA.metadataValidation`
+
+Type: `array` of objects
+Default: `[]` (no validation)
+
+An array of objects, where each object defines validation rules for a specific metadata field. Each object can have
+the following properties:
+
+*   `identifier` (string, required): The name of the metadata field to validate (e.g., `author`, `version`).
+*   `required` (boolean, optional): If `true`, the metadata field must be present in the rule. Defaults to `false`.
+*   `type` (string, optional): Specifies the expected type of the metadata value. Valid values are
+    `"string"`, `"integer"`, `"float"`, and `"bool"`. If the value does not match the specified type, a warning will
+    be generated.
