check_public_pdf
Check a public PDF
Downloads one PDF from a public http or https link and reports the structure that screen readers use: whether the file is tagged, whether it has a document title and a language, how many images have no text description and on which pages, and reading-order signals (pages with columns are flagged for a person to check). Also reports the page count and which pages look scanned or contain tables. Use when the user gives a link to a PDF on a public website and asks about its accessibility or screen-reader structure. Does not open files behind a login, does not change the file, and does not say whether the file meets PDF/UA, WCAG or any law.
