qr-code is a skill for Claude Code from AlteredCraft/claude-code-plugins. It costs 112 tokens per session (977 once invoked), scanned A, original, MIT.

A tool for turning a URL, text, Wi‑Fi details, contact information, or other data into a QR code, a scannable square image. It can save the result as SVG, PNG, EPS, PDF, or text.

In plain words
What is it for?
Use it to create QR codes for websites, printed materials, Wi‑Fi access, contact cards, or other shared information.
Why use it?
It removes the need to find a separate QR-code website or configure an image export by hand.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

qr-code 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_qr.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QR Code Generator

Generate QR codes from any text or URL data, with support for multiple output formats and visual customization.

Workflow

  1. Ask where to save the output file:
    • Desktop: ~/Desktop/my_qr.svg
    • Downloads: ~/Downloads/my_qr.svg
    • Current project directory
    • A specific path they provide
  2. Run scripts/generate_qr.py via uv run with the user's data and desired options.
  3. Present the result to the user.

Script Usage

The script uses PEP 723 inline metadata to declare its dependency (segno). Run it with uv run and dependencies are resolved and cached automatically — no manual installation required.

uv run ${CLAUDE_PLUGIN_ROOT}/skills/qr-code/scripts/generate_qr.py DATA OUTPUT_PATH [options]

Required Arguments

Argument Description
DATA The content to encode (URL, text, etc.)
OUTPUT_PATH Output file path. Extension determines format: .svg, .png, .eps, .pdf, .txt

Options

Option Default Description
--scale 10 Module scale factor (pixels per module)
--border 4 Quiet zone border width in modules
--dark #000000 Dark module color (hex)
--light #ffffff Light module color (hex)
--error M Error correction: L=7%, M=15%, Q=25%, H=30%
--version auto Force a specific QR version (1-40)
--micro off Create a Micro QR Code (for very short data)
--transparent off Transparent background (SVG/PNG only)

Format Guidance

  • SVG (.svg): Recommended default. Scalable vector, ideal for print and web. Smallest file size.
  • PNG (.png): Raster image. Requires pillow as an additional dependency. Good for embedding in documents.
  • EPS (.eps): Vector format for professional print workflows.
  • PDF (.pdf): Vector PDF, good for print-ready documents.

Default to SVG unless the user requests otherwise.

What ships with it

1 file 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.

Changes

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.
