Provides fallback methods for extracting PDF text when the usual file reader fails or returns incomplete content. Uses command-line tools or Python libraries to retrieve text, preserve spacing, inspect metadata, and extract tables.

Extract text from PDFs using shell tools when read_file fails
安装前可以查看交给 AI 代理的指令内容。
Use this skill when read_file with filetype='pdf':
The built-in PDF handler is unreliable for structured text extraction. Shell-based tools provide more robust alternatives.
# Extract text from PDF to stdout
pdftotext /path/to/file.pdf -
# Extract text to a file
pdftotext /path/to/file.pdf output.txt
# Preserve layout (maintains spacing/structure)
pdftotext -layout /path/to/file.pdf output.txt
Usage in agent:
run_shell command="pdftotext -layout /path/to/document.pdf -"
# Get PDF metadata (pages, author, creation date, etc.)
pdfinfo /path/to/file.pdf
Usage in agent:
run_shell command="pdfinfo /path/to/document.pdf"
import fitz # PyMuPDF
doc = fitz.open("/path/to/file.pdf")
text = ""
for page in doc:
text += page.get_text()
doc.close()
print(text)
Usage in agent:
run_shell command="python3 -c \"import fitz; doc=fitz.open('file.pdf'); print(''.join(p.get_text() for p in doc))\""
import pdfplumber
with pdfplumber.open("/path/to/file.pdf") as pdf:
for page in pdf.pages:
text = page.extract_text()
tables = page.extract_tables() # For tabular data
Usage in agent:
run_shell command="python3 -c \"import pdfplumber; pdf=pdfplumber.open('file.pdf'); print(''.join(p.extract_text() or '' for p in pdf.pages))\""
Try pdftotext first - Fastest and most reliable for plain text
run_shell command="pdftotext -layout /path/to/file.pdf -"
If pdftotext unavailable, check for Python libraries
run_shell command="python3 -c \"import fitz; print('PyMuPDF available')\""
For table/structured data, use pdfplumber
run_shell command="python3 -c \"import pdfplumber; ...\""
Verify extraction succeeded - Check output contains readable text, not binary data
If tools are not available:
# Ubuntu/Debian
apt-get install poppler-utils # pdftotext, pdfinfo
# Install Python libraries
pip install pymupdf pdfplumber
read_file with filetype='pdf' for critical text extraction# Step 1: Try pdftotext
RESULT=$(pdftotext -layout /path/to/form.pdf - 2>/dev/null)
# Step 2: Verify we got text, not error
if [ -z "$RESULT" ]; then
# Fallback to Python
RESULT=$(python3 -c "import fitz; doc=fitz.open('/path/to/form.pdf'); print(''.join(p.get_text() for p in doc))")
fi
# Step 3: Use extracted text
echo "$RESULT"

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.
