Pdf Watermark Chinese

PDF 水印添加和移除功能，支持文本和图像水印

This skill appears to do what it says: add/remove text and image watermarks and support Chinese fonts. Before installing, note: (1) you must have PyPDF2 and reportlab available (the skill doesn't auto-install them); (2) the code reads and writes files you provide and probes local font files (it runs fc-list and checks common font paths) — this is normal for Chinese font support but means it will access your filesystem; (3) there are no network calls or credential requirements in the provided files; (4) review pdf_watermark.py (the larger file) if you want to confirm the 'remove watermark' and batch-processing implementations and to ensure it matches your expectations. Run the tool on non-sensitive files first and ensure file permissions/paths are what you expect.

Type: OpenClaw Skill Name: pdf-watermark-chinese Version: 1.0.0 The skill bundle provides legitimate functionality for adding text and image watermarks to PDF files, with specific support for Chinese fonts. It uses standard libraries like PyPDF2 and reportlab. While it utilizes subprocess.run to call 'fc-list' for font detection in pdf_watermark.py, the command is static and does not pose a shell injection risk. No evidence of data exfiltration, malicious execution, or prompt injection was found.
