Combine PDF Files

Combine multiple PDF files into a single PDF document.

Usage

The user can specify:

A directory containing PDF files (files will be sorted alphabetically by filename)
Multiple specific PDF file paths (order is preserved as given)
Output file path for the combined PDF

Script Details

Script location: $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py
Dependency: PyMuPDF (fitz) - pip install PyMuPDF

Instructions

Determine the source PDF files:

If user provides a directory, all PDFs in that directory will be combined in alphabetical order
If user provides specific file paths, use them in the exact order provided

Determine the output file path:

If user specifies an output path, use it
If not specified, ask the user for the output file name/path

Run the combine script:

python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py <input1.pdf> <input2.pdf> ... -o <output.pdf>

Or for a directory:

python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py <directory> -o <output.pdf>

Report the results to the user (number of files combined, total pages, output location)

Examples

Combine specific files in order

python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py \
  chapter1.pdf chapter2.pdf chapter3.pdf \
  -o book.pdf

Combine all PDFs in a directory (alphabetical order)

python3 $HOME/.claude/skills/pdf-combine/scripts/combine_pdfs.py \
  ./documents/ \
  -o combined.pdf

Order Rules

Directory input: Files are sorted alphabetically by filename (case-insensitive)
Explicit file list: Files are combined in the exact order provided by the user
If user wants a specific order for files in a directory, they should provide the files explicitly

Error Handling

If a file doesn't exist, the script will report an error
If no PDF files are found in a directory, the script will report an error
Non-PDF files are skipped with a warning
