img-upload

What This Skill Does

The img-upload skill is a dedicated utility for OpenClaw agents designed to bridge the gap between local image files and public-facing content. It functions as a secure bridge to the img.scdn.io hosting service. When triggered, the agent takes a local image path, processes the file, and performs a network-based upload to the image hosting service. Upon successful completion, the skill returns a stable, public URL suitable for embedding in messages, documentation, or social platforms. Additionally, it provides a secondary delete_url, which is crucial for lifecycle management of the uploaded assets.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. Ensure your system has the necessary network permissions to communicate with the CDN service. Run the following command in your terminal:

clawhub install openclaw/skills/skills/big-dust/img-upload

Once installed, verify the skill is available in your active agents by checking the skill manifest registry.

Use Cases

This skill is indispensable for scenarios requiring content dissemination. Use it when:

• A user requests a shareable link for a screenshot they just provided.
• You have generated an image locally and need to pass a public URL to an external API or recipient.
• You are drafting documentation and need to host static images referenced in the content.
• The user specifically asks for 'image hosting', 'public image links', or 'uploading to a CDN'.

Example Prompts

1. "I've just taken a screenshot of this bug, can you upload it to a public link so I can add it to the GitHub issue?"
2. "Please upload the image I just generated to a free image host and give me the URL."
3. "I have an image file here at '/home/user/photo.png'. Can you make this accessible via a public URL for me?"

Tips & Limitations

• Safety: Always verify that the image does not contain sensitive personal information, as the uploaded content is public-facing.
• Storage: Use the delete_url responsibly. If you are uploading temporary test data, be sure to clean up your assets to keep the cloud storage organized.
• Performance: Ensure the local file path is valid and the file format is supported by standard web browsers (JPEG, PNG, GIF) before invoking the skill.
• Scope: Avoid using this skill for tasks that can be performed locally. If the user only needs the image for a local transformation, unnecessary network traffic should be avoided to preserve speed and privacy.
