Fix status: documented_behavior Other error fragments: - PDF is password protected. Try using a CLI tool to extract or convert the PDF. - The PDF file was not valid. Try converting it to text first (e.g., pdftotext). Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors#pdf-errors (official_docs, unknown, documented_behavior): Docs: 100-page/20MB limit; read page ranges or pdftotext; remove passwords or re-export.
