Recover PDF text extraction when read_file returns binary data by using pdftotext via shell
安装前可以查看交给 AI 代理的指令内容。
Apply this pattern when:
read_file on a PDF returns binary/image data instead of readable textexecute_code_sandbox fails or returns garbled contentThe 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.
Recognize extraction failure when:
read_file returns binary content, image data, or garbled textExtract to stdout (recommended for quick extraction):
pdftotext /path/to/file.pdf -
The - argument outputs directly to stdout for easy capture in your tool response.
Example:
run_shell("pdftotext document.pdf -")
Preserve layout (maintains original formatting):
pdftotext -layout /path/to/file.pdf -
Extract to a file (for large PDFs):
pdftotext /path/to/file.pdf /path/to/output.txt
Then read the output file with read_file.
Handle encoded text:
pdftotext -enc UTF-8 /path/to/file.pdf -
Basic extraction:
# Simple text extraction
text = run_shell("pdftotext document.pdf -")
With error handling:
# Try extraction, check for success
result = run_shell("pdftotext document.pdf - && echo 'SUCCESS' || echo 'FAILED'")
Multi-page PDF with layout:
# Preserve tables and formatting
text = run_shell("pdftotext -layout document.pdf -")
| Issue | Solution |
|---|---|
pdftotext: command not found | Install poppler-utils: apt-get install poppler-utils |
| Garbled/special characters | Try -enc UTF-8 or -enc ASCII7 |
| Missing formatting | Use -layout flag |
| Scanned PDF (no text) | Requires OCR (e.g., tesseract), not text extraction |
| Large PDF timeout | Extract to file instead of stdout |

Prepare audio stems, the separate parts of a track, for mixing by matching their durations with silence, loops, or crossfades. Verify each generated and processed file before moving to the next production step.

Produce audio in separate stems, meaning individual instrument tracks, and verify each output as you go. Align track lengths with silence, loops, or crossfades, then apply effects, mix a master, and package the files.

Keep document creation moving when web searches and page retrieval repeatedly fail. The skill preserves the original task, uses the model’s existing knowledge, and clearly identifies information that could not be checked against external sources.

When Python execution repeatedly fails in execute_code_sandbox, use a file-based alternative: save the script, run it through the shell, and capture results or errors. The guidance covers paths, imports, timeouts, structured output, and optional cleanup.
