qr-generator

What This Skill Does

The qr-generator skill is a versatile utility designed for OpenClaw agents to transform textual information—such as URLs, authentication tokens, WiFi credentials, or short notes—into scannable QR code formats. By bridging the gap between desktop-based AI workspaces and mobile devices, this skill allows for seamless data transfer. Whether you need to push a deep link to a teammate's mobile app or provide a quick way to share sensitive configuration data, this tool handles both static image generation (PNG/SVG) and real-time terminal-based ASCII rendering.

Installation

To integrate this skill into your local OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/autogame-17/qr-generator Ensure you have Node.js installed, as this skill relies on the standard OpenClaw execution environment for processing CLI arguments and generating image files.

Use Cases

1. Mobile Hand-offs: Instantly transfer long, complex URLs from your agent's clipboard to a mobile browser for immediate inspection.
2. Configuration Sharing: Generate QR codes containing WiFi network names and passwords for guest access, displayed directly on your screen.
3. Physical-Digital Integration: Generate scannable tickets, event links, or contact details to be shared with team members during meetings.
4. Credential Provisioning: Safely pass authentication tokens or temporary login keys to mobile apps that support scanning input.

Example Prompts

1. "Generate a QR code for https://docs.openclaw.ai and save it as docs.png."
2. "Show me a QR code in the terminal for the string 'Hello OpenClaw' so I can quickly scan it."
3. "Create a large 1000px wide QR code for my personal website url and save it to the desktop."

Tips & Limitations

• Tip: When generating QR codes for mobile scanning, stick to the default white/black colors to ensure maximum contrast for camera sensors.
• Tip: Combine this with the feishu-image skill for an automated workflow to send data directly to team members via chat.
• Limitation: The skill performs file writing. Ensure you have appropriate write permissions in your chosen output directory.
• Limitation: Extremely long text strings may result in dense QR codes that are harder to scan with low-resolution mobile cameras; keep data concise for the best results.
