-| Syntax | Description |
-| ------------- | ------------- |
-| `@name name` | Set diagnostic name (only outside of the function group). |
-| `@error message...` | Set `severity = error` and report text to `message`. |
-| `@warning message...` | Set `severity = warning` and report text to `message`. |
-| `@maybe message...` | Set `severity = maybe` and report text to `message`. |
-| `@fix template...` | Provide a quickfix template for the rule. |
-| `@scope scope_kind` | Controls where rule can be applied. `scope_kind` is `all`, `root` or `local`. |
-| `@location $var` | Selects a sub-expr from a match by a matcher var that defines report cursor position. |
