+description: >-
+  ast-grep is a powerful tool designed for managing code at scale using
+  Abstract Syntax Trees (AST). Think of it as a hybrid of grep, eslint, and codemod,
+  with the ability to search, lint, and rewrite code based on its structure rather than plain text.
+
+  It supports multiple languages and is designed to be extensible, allowing you to register custom languages.
