# pdftotext Fallback for PDF Text Extraction

## When to Use

Apply this pattern when:
- `read_file` on a PDF returns binary/image data instead of readable text
- Python-based PDF extraction (PyMuPDF, pdfplumber, etc.) in `execute_code_sandbox` fails or returns garbled content
- You need reliable text extraction from PDF files as a recovery strategy

## Why This Works

The `pdftotext` utility (from poppler-utils) is a mature, command-line tool that handles many PDF edge cases that confuse Python libraries or the `read_file` tool. It's pre-installed on most Linux systems and provides consistent, reliable text extraction.
