# QR Code Generator

## Workspace Context

Read bootstrap context before asking questions: `strategy/brand.md` for brand, audience, offer, channels, tools, constraints, and metrics; `about/me.md` for personal voice; `content/ideas.md` and `content/calendar.md` for content planning. Use legacy product-marketing context files only as fallback. Save generated drafts to `content/<platform>/drafts/YYYY-MM-DD_short-topic-slug.md`, and route durable learnings back to `strategy/brand.md`, `about/me.md`, or `content/ideas.md`.

## Operating Contract

This skill is self-contained for its frontmatter scope: use its local instructions, references, scripts, and assets as the playbook; ask only for missing task-specific inputs; hand off to adjacent skills instead of expanding scope; and return an actionable artifact, decision, plan, draft, or diagnostic.



## 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)
4) Export:
   - PNG (good for web)
   - SVG (best for print)
5) If caption enabled:
   - PNG: add label and/or URL under the QR
   - SVG: add a text element under the QR
6) 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)

## Scripts in this pack
- `scripts/generate_qr.py` — single QR (PNG/SVG, optional caption)
- `scripts/batch_generate.py` — batch from CSV (id,url,label)

## Templates
- `assets/templates/utm_template.json`
- `assets/templates/print_notes.md`
- `assets/templates/prompt_snippets.md`
