What This Skill Does

The wechat-image-generator is a specialized automation skill designed for OpenClaw agents to create professional, high-quality visuals specifically tailored for WeChat articles and social media content. Unlike traditional AI image generators that rely on resource-heavy diffusion models, this skill uses a pre-built template engine combined with automated browser screenshots. By rendering custom HTML/CSS templates locally and capturing them as images, it provides a 'zero token cost' alternative for repetitive tasks like article covers, side-by-side comparison graphics, and data charts. This ensures consistent branding and high resolution while minimizing the computational overhead typical of large AI models.

Installation

To integrate this skill into your OpenClaw environment, ensure you have Python 3 installed and the OpenClaw browser tool configured. Execute the following command in your terminal:

clawhub install openclaw/skills/skills/jingyu525/wechat-image-generator

Once installed, the agent will automatically recognize the associated triggers and be able to execute the underlying generation scripts whenever a user requests visual content.

Use Cases

This skill is ideal for content creators, developers, and marketers managing technical blogs or WeChat public accounts.

• Article Covers: Quickly generate branded headers that include titles and subtitles, maintaining a professional aesthetic across all posts.
• Feature Comparisons: Use the comparison template to visually demonstrate the difference between your product and legacy solutions, perfect for marketing documentation.
• Data Visualization: Convert raw performance data into clean, readable charts, effectively communicating technical benchmarks like latency or token savings.

Example Prompts

1. "帮我生成一张公众号封面图，标题写『开源AI新进展』，副标题写『效率提升50%』"
2. "生成一张对比图，左边写『旧版API』，右边写『OpenClaw接口』，标签标注『性能优化』"
3. "用图表展示一下数据：Token消耗:5000,800，生成耗时:30,2，标签分别是『云端处理』和『本地渲染』"

Tips & Limitations

• Tips: For best results, keep titles concise to ensure they fit well within the pre-defined template containers. Use the comparison tool for clear, binary distinctions to maximize visual impact.
• Limitations: As this tool relies on HTML/CSS templates, it is not a generative art model. It cannot create abstract illustrations or photos from scratch. It is best used for structured, information-heavy graphics. Ensure the OpenClaw browser tool is correctly configured, as the screenshot functionality is a mandatory dependency for the generation pipeline.
