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 | $0.00049 | $0.00318 |
| Opus 5 | $0.00024 | $0.00159 |
| Sonnet 5 | $0.00010 | $0.00064 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
qr scanned grade A with 1 finding 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 3d ago.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s "https://api.qrserver.com/v1/create-qr-code/?size=200x200&data=Hello" -o qr.png What it actually says
qr — skill0
Generate QR codes from text or URLs. Terminal display, PNG output, or pure shell encoding.
Quick Start
# With x-cmd
x qr "Hello World" # Terminal QR code
x qr "https://example.com" # URL to QR
# Without x-cmd — use Python
pip install qrcode
python3 -c "import qrcode; qrcode.make('Hello').save('qr.png')"
# Or use online API
curl -s "https://api.qrserver.com/v1/create-qr-code/?size=200x200&data=Hello" -o qr.png
What's Available
- Terminal — Display QR in terminal
- PNG — Generate PNG file
- Pure shell — AWK-based encoding (no deps)
This skill0 grows
Starting with the essentials. Will add:
- QR encoding algorithms
- Error correction levels
- WiFi QR format

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 is a skill published in the GitHub repository x-cmd/x-cmd (4,630 stars, last pushed yesterday), licensed Apache-2.0. It adds 49 tokens to every session and 318 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
