Convert Document To Markdown

Use this skill when a user wants a supported local file converted into Markdown for later processing.

What this skill does

• Converts supported local files into Markdown: .pdf, .docx, .pptx, .xlsx, .jpg, .jpeg, .png, .gif, .bmp, .txt, .json, .xml, .md
• Image handling modes are file-type dependent: ocr / vl / none for .docx, .pptx, .xlsx, and image files; ocr / vl / vl-page / none for .pdf
• Only runs through Docker. Do not use local Python execution as an operational path.
• Uses a prebuilt Aliyun CR image with fixed version 0.0.1: convert-document-to-markdown-arm64:0.0.1 on ARM64 hosts, convert-document-to-markdown-x64:0.0.1 on x64 hosts
• Returns structured JSON by default so later tool calls can consume markdown, logs, and meta.
• Reads one-time VL configuration from OpenClaw skill config or the repository .env file, then forwards it into the container automatically.
• Only exposes the file command. URL, health, and version commands are intentionally removed to keep startup lean.
• Do not use latest, do not build a fallback image at runtime, and do not treat .doc, .ppt, .xls, audio files, or unlisted image formats as supported inputs.
