QR Code Generator

What this skill does

Given a URL, this skill generates:

• a QR code that encodes the URL
• optional captions (human-readable URL or short label)
• exports in PNG and/or SVG
• optional batch runs from a CSV

Guardrails

• Don’t generate QR codes for suspicious links (phishing, credential prompts, malware). If unsure, ask for confirmation or suggest a safer destination page.
• Prefer HTTPS URLs.
• If the QR is for print, prefer SVG (scales cleanly) and high error correction.

Inputs

Required:

• URL

Optional:

• label/caption text (e.g., “Scan to book a call”)
• whether to show the URL under the QR (yes/no)
• output formats: PNG, SVG
• UTM params (source, medium, campaign, content, term)
• size intent: screen / print / sticker

Workflow

1. Validate the URL (scheme + domain).
2. Optionally append UTM parameters (using assets/templates/utm_template.json).
3. Generate QR:

- Error correction: M (default), H for print/complex usage - Border: 4 (default)

1. Export:

- PNG (good for web) - SVG (best for print)

1. If caption enabled:

- PNG: add label and/or URL under the QR - SVG: add a text element under the QR

1. Return links + a quick “usage notes” block (recommended minimum size, print tips).

Output format (required)

• Encoded URL (final URL after UTM, if used)
• Files generated (with links)
• Recommendations (error correction, min size, when to use SVG vs PNG)
