      description: "Upload a supported well-known file to a site.\n\nThe current restrictions on well-known files are as follows:\n  - Each file must be smaller than 100kb\n  - Less than 30 total files\n  - Have one of the following file extensions (or no extension): `.txt`, `.json`, `.noext`\n\n  <Note title=\".noext\">\n    `.noext` is a special file extension that removes other extensions. For example, `apple-app-site-association.noext.txt` will be uploaded as `apple-app-site-association`. Use this extension for tools that have trouble uploading extensionless files.\n  </Note>\n\n<Warning title=\"Enterprise Only\">This endpoint requires an Enterprise workspace.</Warning>\n\nRequired scope: `site_config:write`\n"
