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 | $0.00112 | $0.00977 |
| Opus 5 | $0.00056 | $0.00489 |
| Sonnet 5 | $0.00022 | $0.00195 |
| Haiku 4.5 | $0.00011 | $0.00098 |
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 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.
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
- 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
- Desktop:
- Run
scripts/generate_qr.pyviauv runwith the user's data and desired options. - 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]

--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. Requirespillowas 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.
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 is a skill published in the GitHub repository AlteredCraft/claude-code-plugins (13 stars, last pushed 3mo ago), licensed MIT. It adds 112 tokens to every session and 977 once invoked, about $0.0006 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 2026-08-30.
