CLI that strips prompt-injection triggers from academic papers
Project description
🧼 Paper-Sanitizer
Strip prompt-injection tricks from academic papers before they hit your LLM pipeline.
Researchers keep showing how easy it is to hide
Ignore all previous instructions
inside a PDF or LaTeX file and fool automated summarizers. Paper-Sanitizer is a tiny command-line tool that removes those hidden instructions, flags stealthy white-on-white text, and rates the overall risk. Use it as a pre-flight check in RAG systems, peer-review helpers, or your own reading workflow.
Key features
| Stage | What it does |
|---|---|
| Stage 1 | Regex firewall – removes obvious prompt-injection phrases |
| Stage 2 | Detects invisible text (white or ≤ 1 pt) and suspicious PDF metadata |
| Stage 3 | Emits detailed event log, word-level diff (--diff), and a risk class (low / medium / high) |
Supported inputs: PDF, .tex, .txt (more coming).
