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.

這是一款安全意識較強的 PDF 提取工具，能夠有效防止提取的內容被意外洩露或傳播。它在保護敏感資訊方面做了充分考慮，但功能相對基礎，只適合處理普通文本類 PDF 檔案。對於需要處理更復雜文件的使用者來說，可能需要額外的工具配合使用。整體質量中規中矩，安全防護是亮點，功能豐富度則是短板。
