The issue shows a screenshot of broken references in built-in function documentation, but does not specify which files or functions are affected. Look for documentation files in the repository, likely in a docs/ directory, and search for markdown links or references to built-in functions. Check the rendered output to identify broken links, then correct the markdown syntax or file paths.
