+# at-use-no-redundant-alias
+
+By default, the module's namespace is just the last component of the module’s URL.
+This rule is to disallow redundant namespace aliases.
+
+```scss
+@use "foo" as foo;
+/**           ↑
+ * Disallow this */
+```
+
+The following patterns are considered warnings:
+
+```scss
+@use "foo" as foo;
+```
+
+```scss
+@use "sass:math" as math;
+```
+
+```scss
+@use "src/corners" as corners;
+```
+
+The following patterns are _not_ considered warnings:
+
+```scss
+@use "foo" as bar;
+```
+
+```scss
+@use "sass:math";
+```
+
+```scss
+@use "src/corners" as c;
+```
