Using PDFs for depth (not noise)

PDFs are perfect for evidence—security whitepapers, datasheets, and long policies. They are a poor substitute for a structured knowledge brief. Use them to support answers, not to dump hundreds of pages the model must guess inside.

When a PDF earns a place in your knowledge stack

Authoritative detailvisitors ask for by name (“SOC 2 report,” “API limits,” “HIPAA overview”).
Stable content that rarely changes—better than fragile copy-paste across pages.
Formatted artifacts where tables and diagrams carry meaning HTML pages lack.

Skip PDFs that duplicate your homepage in brochure form unless the PDF is the signed-off version legal expects you to cite.

Managing overlap with the website

If web and PDF disagree, the agent will hesitate or hallucinate bridges. Pick a winnerper topic and note it in the brief: “If the datasheet and /pricing differ, trust /pricing for numbers.”

Version PDFs clearly in the filename or title block (“Security_Overview_2026.pdf”) so you can spot stale uploads during audits.

Index PDFs in the brief

Add a short bullet list in your knowledge brief: each PDF, what it covers, and when to prefer it over web copy. That single habit prevents the model from treating every file as equally important.

Size discipline

Many small, purposeful PDFs usually beat one giant bundle. Large documents dilute retrieval unless the brief tells the agent which sections matter for which questions.
