What is Ark Image Generator?
The Ark Image Generator is a specialized tool designed for Openclaw Skills to facilitate seamless text-to-image generation through the Volcano Engine Ark (Doubao) API. It bridges the gap between AI coding agents and advanced visual creation, allowing for the generation of avatars, article covers, and marketing posters directly from text descriptions. By utilizing an OpenAI-compatible API structure, it provides a familiar and reliable integration path for developers using Openclaw Skills.
This skill is architected for efficiency and flexibility; it focuses on retrieving and returning direct image URLs rather than managing local file downloads. This approach allows the calling agent or workflow to decide exactly how to handle the resulting assets, whether that involves further processing, local storage, or direct delivery to an end-user. It is a lightweight yet powerful addition to any developer's toolkit within the Openclaw Skills ecosystem.
Ark Image Generator Use Cases
- Creating custom avatars and profile pictures for application users.
- Generating high-resolution covers and headers for digital articles or blog posts.
- Producing marketing posters and social media content from long-form structured prompts.
- Automating the creation of visual placeholders and design assets during the development process.
How Ark Image Generator Works
- The user provides an image description or prompt to the agent.
- For standard requests, the skill processes the prompt directly via the CLI.
- For long or complex prompts, the system writes the description to a specific temporary file within the workspace data directory to avoid command-line length limitations.
- The script authenticates with Volcano Engine Ark using environmental variables and sends the prompt to the specified model endpoint.
- The Ark API generates the image and returns a signed, temporary URL.
- The skill outputs the URL as the final result, enabling Openclaw Skills to pass the link to subsequent tasks or users.
Ark Image Generator Setup
To integrate this into your workflow, ensure you have your Volcano Engine credentials ready. Set the required environment variables in your terminal or configuration file:
export ARK_API_KEY="your_volcano_ark_api_key"
export ARK_IMAGE_MODEL="your_model_endpoint_id"
Run the generator using Python:
# Direct prompt usage
python scripts/xqximage.py "A futuristic neon city" 4K
# Long-form prompt usage via file
python scripts/xqximage.py --file
Ark Image Generator Data Schema & Taxonomy
The skill manages its temporary data within the project's workspace to ensure compatibility with Openclaw Skills standards:

|---|---|---|
| Prompt File | wdatas/xqx-img-prompt.txt |
Stores long-form text descriptions for complex image generation. |
| Script Core | scripts/xqximage.py |
Main execution logic and API interaction layer. |
| Output | stdout |
Returns process logs and the final image URL on the last line. |
Ark Image Generator Advanced Features
- Support for multiple resolution presets including 2K, 4K, and specific aspect ratios like 2560x1440.
- File-mode processing (
--file) which allows for highly detailed, multi-paragraph visual descriptions without shell character limits. - Native integration with Openclaw Skills workspace structures for automated agent workflows.
