How to get mdast？

[NoiseFan]

First of all, thank you very much for taking the time to help me look at the problem!

Background

I'm making a markdown linter and I want to get the AST of the markdown and do some fixes.
Now the problem, I only got a JS AST

...
create(context) {
    console.log(context.sourceCode.ast)
    return {
    }
  },
...

export const plugin: ESLint.Plugin = {
  rules: {
    // some rules
    'some-rules': rules.someRules,
  },
}
export default plugin

 {
    files: ['**/*.md'],
    plugins: {
      markdown,
      plugin,
    },
    language: 'markdown/commonmark',
    rules: {
      'plugin/some-rules': 'error',
    },
  },

output reuslt

 {
  body: [],
  comments: [],
  loc: { end: 110, start: 0 },
  range: [ 0, 110 ],
  tokens: [],
  type: 'Program',
  parent: null
}

I want to get markdown ast, what should I do? I hope to get your help, thank you!

There's not enough detail about how you're running ESLint to know what's going on, but your configuration is wrong if this is what you're getting. See this page for tips on how to debug your configuration:
