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: 1 finding, 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 →
- medium Privilege Escalation · line 40 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
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 | $0.02195 |
| Opus 5 | $0.00026 | $0.01097 |
| Sonnet 5 | $0.00011 | $0.00439 |
| Haiku 4.5 | $0.00005 | $0.00219 |
Grade B, and why
librecad 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
LibreCAD 主要特性：
- 2D 矢量绘图：线/圆/弧/椭圆/多段线/样条/标注/文字/图案填充
- 图层、块、属性、坐标输入（绝对/相对/极坐标）
- 文件：DXF（R12/R2007 读写）、PDF/SVG/PNG（导出）、DWG（通过 ODA File Converter 或 LibreDWG 转换）
- 跨平台：Windows、macOS、Linux
- 国际化：含完善的中文界面
读写 DWG 原生支持有限，建议先用 LibreDWG 或 ODA 转 DXF。
安装
# Linux
sudo apt install librecad
# macOS
brew install librecad
# Windows / 其它：从官网下载
界面与基本操作

图层与块
- 图层：右侧面板 → New，可设置颜色/线型/线宽/打印开关
- 块：选中要素 → 右键 → Create Block，或 Drawing → Block → New
- 当前图层在状态栏切换；锁定/隐藏/冻结按钮
标注
- 线性、对齐、半径、直径、角度、引线
- 标注样式：
Options → Drawing Preferences → Dimensions - 全局标注比例 + 字高
图案填充与文字
- Hatch：选中边界 → 选图案（ANSI/ISO/Earth/Solid）+ 比例 + 角度
- 文字：单行 / 多行；支持 SHX 与 TTF 字体；中文使用
Noto Sans CJK SC等
文件交互
# DXF（自带）
File → Open / Save As / Export
# DWG → DXF（需要 ODA File Converter）
ODAFileConverter input.dwg . ACAD2010 DXF 1 0
# 或
dwg2dxf -y input.dwg # LibreDWG
# 导出 PDF
File → Export → Export as PDF
命令行（无界面）
# 启动并运行命令脚本（需自定义脚本插件支持）
librecad --no-startup-window
# 配合 dxf-tools / Python 脚本批处理
LibreCAD 自身脚本能力较弱；批量转换建议结合：
- LibreDWG 转换 DWG ↔ DXF
ezdxf（Python 库）做 DXF 解析与生成inkscape做 DXF → SVG/PDF
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.

librecad is a skill published in the GitHub repository znlgis/opengis-skills (61 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 2,195 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.
