Add bleed margins to a PDF for commercial print shops that trim — extends the page size by the bleed amount on each side and shifts content to the new center. Most office digital printing does NOT need this; use only when sending to a print shop. Triggers on phrases like "add bleed", "add 3mm bleed", "prep for trim".
Generate a matching-size cover page with a title (and optional subtitle, author, date) and prepend it to a PDF. Triggers on phrases like "add a cover page", "prepend a title page", "make a cover for this PDF".
Overlay a diagonal text watermark (DRAFT, PRIVATE, CONFIDENTIAL, etc.) at 45° across every page in light red (or user-specified color), at low opacity so body text remains readable. Triggers on phrases like "add a DRAFT watermark", "stamp PRIVATE on every page", "watermark this PDF".
Burn a permanent footer label into every page of a PDF — CLIENT CONFIDENTIAL, PRIVATE, FAMILY DISTRIBUTION, DRAFT, EMBARGOED UNTIL ..., or custom text. User can choose font and size. Renders a PNG preview to verify layout before committing. Triggers on phrases like "add a CONFIDENTIAL footer", "burn in a footer", "stamp 'embargoed until' across the bottom".
Convert a color PDF to grayscale (black-and-white) for monochrome digital printing — saves toner and avoids color-mismatch issues. Triggers on phrases like "convert PDF to grayscale", "make it black and white", "remove color from PDF", "monochrome PDF".
Bundle one or more print-ready PDFs into a single "print job" folder with a manifest, ready to hand to a digital printer or share with collaborators. Triggers on phrases like "create a print job", "bundle these PDFs", "make a job folder for the printer".

Produce a new PDF with the specified pages removed.
55-71,3,5,71,3-5,12,20-endblank (auto-detect blank pages), last, first<input>-trimmed.pdf.qpdf is the cleanest option — it supports inverse selection natively. pdftk and mutool are alternatives.
qpdf --empty --pages input.pdf 1-4,6-z -- output.pdf
The trick: qpdf can't directly remove pages, but it can select the pages you want to keep. Compute the inverse of the user's removal list against the page count.
pdfinfo input.pdf | awk '/^Pages:/ {print $2}'
For blank mode, render each page to a low-res PNG and check whether the image is essentially uniform white:
gs -sDEVICE=png16m -r50 -o /tmp/p%d.png input.pdf
# then for each PNG, use ImageMagick: identify -format "%[mean]" /tmp/p1.png
# values close to 65535 (16-bit max) ≈ blank
pdfinfo output.pdf | grep Pages and confirm new count = old - removed.Trimmed PDF at the requested path. Original is preserved.
