Pattern **/*.mdx: "ALWAYS review Markdown content THOROUGHLY with the following criteria:

• Use proper nouns in place of personal pronouns like 'We' and 'Our' to maintain consistency in communal documentation.
• Avoid gender-specific language and use the imperative form.
• Monitor capitalization for emphasis. Use bold for prominence instead of all caps or italics.
• Ensure proper nouns are capitalized in sentences.
• Apply the Oxford comma.
• Use proper title case for headers, buttons, tab names, page names, and links. Sentence case should be used for body content and short phrases, even in links.
• Use correct spelling and grammar at all times (IMPORTANT).

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
