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.

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 | $0.00043 | $0.02446 |
| Opus 5 | $0.00022 | $0.01223 |
| Sonnet 5 | $0.00009 | $0.00489 |
| Haiku 4.5 | $0.00004 | $0.00245 |
Grade A, and why
lightcad 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 — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.

概述
LightCAD 主要特性：
- 纯前端 CAD：HTML5 Canvas / WebGL 渲染，无插件
- AutoCAD 风格命令行：line / circle / pline / trim / mirror …
- DXF 互通：导入导出 DXF（基于 dxf-parser/dxf-writer）
- 图层 / 块 / 标注 / 文字
- 可嵌入：iframe 或 Web Component
- 二次开发 API：JS/TS 对应实体、命令、事件、UI
该项目处于活跃迭代阶段，下文以通用 Web CAD 二次开发为视角，如细节差异请以仓库 README 与 znlgis 教程为准。
安装与试用
在线试用
直接打开 https://lightcad.cn/ 体验。
嵌入 iframe

实体与图层（API）
// 添加实体
const id = app.add('LINE', { p1: [0,0], p2: [100,100] });
app.add('CIRCLE', { center: [50,50], radius: 20, layer: 'WALL' });
// 修改
app.update(id, { color: '#ff0000', lineWeight: 0.3 });
// 查询
const entities = app.query({ type: 'LINE', layer: 'WALL' });
// 删除
app.remove(id);
// 图层
app.layers.add('WALL', { color: '#0000ff', lineType: 'CONTINUOUS' });
app.layers.setCurrent('WALL');
app.layers.set('WALL', { visible: false });
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.

lightcad is a skill published in the GitHub repository znlgis/opengis-skills (60 stars, last pushed 2d ago), licensed MIT. It adds 43 tokens to every session and 2,446 once invoked, about $0.0002 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.
