Output schema
{'type': 'object', 'additionalProperties': True}
edit_pdf_text
Edit text in PDF
Change, correct or delete text INSIDE the original PDF, keeping its fonts, sizes, colors and layout.
Use this whenever the user wants their existing PDF updated rather than a
new document: fix a typo, change a date, amount, name or address, update a
CV or a price list, translate a heading, remove a line. Read the PDF first,
then pass one edit per change with `find` copied exactly as printed in the
document. Dates and amounts written differently in the PDF (12/08/2026 vs
August 12, 2026; 1240 vs 1,240.00) are matched and rewritten in the
document's format.
