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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.02405 |
| Opus 5 | $0.00026 | $0.01203 |
| Sonnet 5 | $0.00011 | $0.00481 |
| Haiku 4.5 | $0.00005 | $0.00241 |
Grade B, and why
qcad scanned grade B 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 today.
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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

概述
QCAD 由两部分组成:
- QCAD Community Edition:开源核心,支持 DXF(自带)+ DWG(需要 Teigha/ODA File Converter 或 LibreDWG)
- QCAD/CAM 与 QCAD Pro:商业插件(数控、PDF、SVG 详细输出等)
核心能力:
- 2D 绘图:线/弧/圆/多段线/样条/标注/填充/文本
- 图层、块、视图、布局、打印
- DXF/DWG/PDF/SVG 输入输出
- ECMAScript(QtScript / V8)脚本扩展
- 命令行:
qcad、dwg2dxf、dxf2pdf、dxf2bmp等
安装
# 二进制:<https://qcad.org/en/download>
# Linux 自带:sudo apt install qcad
# 命令行
qcad # 启动 GUI
qcad -no-gui -autostart script.js # 无界面运行脚本
将 ODA File Converter(免费)放在 PATH 中以支持 DWG。

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.

qcad is a skill published in the GitHub repository znlgis/opengis-skills (61 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 2,405 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
