PDF to Images

将 PDF 文件转换为图片（PNG/JPG），支持指定分辨率和页码范围

This skill appears to do what it says (convert PDFs to PNG/JPG locally) and does not contact external services or request credentials. However, the package metadata/instructions are incomplete: index.js requires the 'canvas' (node-canvas) module which is not listed, and node-canvas typically needs native libraries (cairo, pango, libjpeg, etc.) or build tools. Before installing or running: 1) ensure you have Node installed; 2) install both pdfjs-dist and canvas (npm install pdfjs-dist canvas) and be prepared to install any native system dependencies for node-canvas (check node-canvas docs for platform-specific steps); 3) run the tool in a sandbox or test environment first to confirm build/run behavior and to avoid accidental file overwrites (the tool writes output files and can overwrite existing paths); 4) verify the license (MIT) and the small codebase manually if you have concerns. If you want this to be easier for end users, ask the author to update the SKILL.md/registry metadata to list 'canvas' and document native prerequisites.

Type: OpenClaw Skill Name: pdf-to-images Version: 1.0.1 The skill provides legitimate functionality for converting PDF files to images locally using the 'pdfjs-dist' and 'canvas' libraries. The implementation in 'index.js' follows standard practices for file handling and PDF rendering without any signs of data exfiltration, unauthorized network access, or malicious command execution.
