md-table-image

What This Skill Does

The md-table-image skill is a specialized utility designed to improve the visual delivery of data within the OpenClaw AI agent environment. By default, LLMs often output data in raw markdown table format, which can be inconsistent in rendering or cluttered on smaller mobile screens. This skill bridges that gap by programmatically converting markdown-formatted tables into high-quality, styled PNG images. It utilizes a rendering engine to parse markdown content, apply visual themes, and export the result as a PNG file, ensuring that your data looks professional, consistent, and readable every time it is shared.

Installation

To integrate this skill into your environment, use the OpenClaw CLI tool. Execute the following command in your terminal: clawhub install openclaw/skills/skills/kirorab/md-table-image Once installed, ensure your environment has the necessary dependencies for the underlying script to function, particularly if you are running it in a containerized setup where puppeteer or a browser-rendering engine might be required.

Use Cases

This skill is indispensable for professionals who need to share complex datasets, budget breakdowns, schedules, or comparative analyses. Instead of sending raw, text-heavy markdown, you can provide a clean image that preserves formatting exactly as intended. Use this for:

• Creating executive-ready dashboards in chat.
• Sharing technical specifications that require column alignment.
• Generating screenshots of data summaries for documentation.
• Exporting project timelines to stakeholders who prefer visual media over raw code blocks.

Example Prompts

1. "Create a comparative table showing the pricing of our three tiers, add the title 'Subscription Comparison', and render it as a dark-themed image using the md-table-image skill."
2. "Extract the latest quarterly earnings data from the attached file, format it into a table, and save it as an image to /tmp/earnings.png."
3. "Generate a Markdown table of the server uptime logs for last week and render it as a PNG file so I can easily embed it in our team report."

Tips & Limitations

To maximize effectiveness, always define a specific width if your table contains long text strings to prevent truncation. The tool defaults to 800px, but complex tables may require adjustment. Keep in mind that as an image-based tool, the resulting PNG cannot be edited by the recipient; ensure the data is verified before generating the final image. Because this skill performs file-writing operations, ensure that your agent has the appropriate permissions for the specified output directory. Always verify the output path matches your system's write permissions to avoid errors during the rendering process.
