Qrcode
Skill by hexavi8
Why use this skill?
Generate professional QR codes in SVG, PNG, or JPG formats using the OpenClaw Qrcode skill. Features custom colors, shapes, and error correction levels.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/hexavi8/qrcodeWhat This Skill Does
The Qrcode skill, developed by hexavi8, is a high-performance utility integrated into the OpenClaw agent ecosystem for the generation of customized, production-ready QR codes. It leverages the robust qrcode library for generation and sharp for advanced image processing, allowing users to move beyond simple pixelated codes. Whether you need a standard SVG for digital signage, a transparent PNG for UI overlays, or a high-quality JPEG for physical printing, this skill provides precise control over styling, error correction levels, and output dimensions.
Installation
To integrate this skill, navigate to your OpenClaw working directory and execute the following command:
clawhub install openclaw/skills/skills/hexavi8/qrcode
Ensure your system has node installed, then verify your environment by running npm install within the skill's base directory. The tool is designed to work seamlessly within the agent's workspace, adhering to strict file isolation security policies.
Use Cases
- Marketing & Branding: Generate stylized, high-contrast QR codes that match corporate color schemes for print ads.
- UI/UX Design: Create transparent PNG QR codes to be embedded into web applications or digital presentations.
- Logistics & Asset Tracking: Generate high-error-correction (H-level) codes suitable for labels that might sustain damage or require high durability.
- URL Management: Quickly encode long, complex tracking URLs into clean, scannable QR images.
Example Prompts
- "Generate a QR code for https://openclaw.ai with a blue color, rounded eyes, and a square dot style. Save it as a PNG."
- "I need a high-resolution print-quality QR code for this link: [insert link], set the error correction to High (H) and output it as a 2048px JPEG."
- "Create a simple SVG QR code for the text 'Welcome Guest' and display it in the chat."
Tips & Limitations
- Error Correction: Always use 'H' (High) error correction if you plan on adding a logo or significantly styling your QR code, as it ensures readability despite visual modifications.
- Security: Note that all output files are restricted to the workspace root. You cannot write files to arbitrary system directories, ensuring your environment remains tidy and secure.
- Performance: For large batches, keep the scale and size parameters reasonable to maintain fast generation times. The maximum image size is 10,000 pixels, which is overkill for almost all digital use cases.
