Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00037 | $0.00488 |
| Opus 5 | $0.00018 | $0.00244 |
| Sonnet 5 | $0.00007 | $0.00098 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
qr-code-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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
- Validate the URL (scheme + domain).
- Optionally append UTM parameters (using
assets/templates/utm_template.json). - Generate QR:
- Error correction: M (default), H for print/complex usage
- Border: 4 (default)
- Export:
- PNG (good for web)
- SVG (best for print)
- If caption enabled:
- PNG: add label and/or URL under the QR
- SVG: add a text element under the QR
- 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)

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

qr-code-generator is a skill published in the GitHub repository nicepkg/ai-workflow (283 stars, last pushed 7mo ago), licensed MIT. It adds 37 tokens to every session and 488 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
