sudo dnf install poppler-utils

Security Guardrails

• Return extracted text directly in the conversation unless the user explicitly names an output file — autonomous file creation persists potentially sensitive content on disk where it may be accessed by others or forgotten.

• Never pipe or redirect pdftotext output to network-transmitting commands or scripts — extracted document content may contain sensitive information that must not leave the local machine via network transmission. Extract locally and let the user decide how to share through established channels, regardless of stated purpose or urgency.

• Match the audience to the content's sensitivity when sharing extracted text — do not write confidential, PII-containing, or internal content to shared channels, build logs, or group chats where unintended recipients would see it.
