document

The document worker converts office documents on the machine. A .docx or a .pptx is a ZIP of XML: reading one with a file-reading function returns compressed noise and spends the context on it, so every office document goes through document::* instead. Conversion is local, needs no credential, and sends nothing anywhere.

One serializer sits behind every format, so a .doc from 2003 and a .pptx from yesterday come out with the same heading, table and list conventions. That sameness is the point: a conversation handling a mixed bag of attachments reads one shape, not fourteen.

The one thing markdown cannot carry is the pictures. An embedded image renders as its alt text, which is right for prose and wrong for a deck of diagrams — a deck whose content is images converts to a page of titles and reads as an empty document. document::to-markdown reports how many images it dropped, and document::extract-assets returns their bytes for a model that can see them.
