Add content to a PDF session
add_pdf_contentAppend text at specified coordinates or insert a blank page into an active PDF session. Build multi-page documents by calling this repeatedly, then save with save_pdf.
Instructions
Append text or a new page to an open create_pdf session (step 2 of 3).
Mutates the in-memory session; nothing is written to disk until save_pdf. Returns JSON {status, session_id, page_count} on success, or {error, code} if the session is missing/inactive or required text fields are absent. Coordinates use PDF points with the origin at the bottom-left of the page.
Call repeatedly to build up pages, then call save_pdf. This only works on a session from create_pdf — to add notes/highlights to an existing PDF file use annotate_pdf instead.
