Get metadata for an open document: title, author, page count, word count, format, file size, dates. Token-efficient: use this before reading document content to understand its size and structure.

Get the structural outline of a document:

• Writer documents: headings hierarchy (H1, H2, H3...)

• Calc spreadsheets: list of sheet names with row/column counts

• Impress presentations: slide titles with index numbers Token-efficient: always call this before document_read_text to understand structure.
