The Agent Skills Directory

[SAFE]: The skill implements a standard utility for EPUB file processing. Technical analysis of the provided Python scripts confirmed that their behavior aligns with the stated purpose of the skill.
[COMMAND_EXECUTION]: Scripts including scripts/extract_epub.py, scripts/rebuild_epub.py, and scripts/validate_epub.py contain subprocess.run calls with shell=True. These were manually reviewed and found to be safe, as they only execute the hardcoded command chcp 65001 to ensure UTF-8 encoding on Windows systems and do not process user-provided strings as shell commands.
[EXTERNAL_DOWNLOADS]: The skill references standard Python dependencies (ebooklib, beautifulsoup4, lxml) available through official package registries. No suspicious remote code execution patterns or downloads from unknown sources were identified.
