# ast-grep YAML queries

ast-grep YAML queries use [ast-grep YAML rules](https://ast-grep.github.io/reference/yaml.html) to match code patterns. Use them for syntax-level counts that do not need custom JSSG logic.

You can generate ast-grep rules with the help of AI [using Codemod Studio](/enterprise/codemod-studio#use-codemod-ai).
