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 | $0.00044 | $0.04069 |
| Opus 5 | $0.00022 | $0.02034 |
| Sonnet 5 | $0.00009 | $0.00814 |
| Haiku 4.5 | $0.00004 | $0.00407 |
Grade A, and why
pyqgis 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 2d 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.
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 — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.

概述
PyQGIS 是 QGIS 桌面 GIS 软件的 Python 绑定层，对应 QGIS 源码中 python/ 目录下的绑定代码。它将 QGIS 核心 C++ 类库完整暴露给 Python，使得开发者可以：
- 在 QGIS Python 控制台中交互式操作
- 编写 独立 Python 脚本（无需启动 QGIS 桌面）
- 开发 QGIS 插件扩展桌面功能
- 调用 Processing 框架执行 100+ 种空间分析算法
- 进行 地图渲染与导出（PNG / PDF / SVG）
PyQGIS 主要包含以下模块：
| 模块 | 说明 |
|---|---|
qgis.core |
核心类——图层、要素、几何、坐标系、项目、Processing 等 |
qgis.gui |
GUI 组件——地图画布、地图工具、符号选择器等 |
qgis.analysis |
空间分析——插值、网络分析、栅格计算等 |
qgis.processing |
Processing 算法调用入口（processing.run()） |
qgis.server |
QGIS Server Python 插件接口 |
qgis.3d |
3D 地图视图相关类 |
qgis.PyQt |
PyQt5/PyQt6 兼容层 |
环境准备
前置条件
- 安装 QGIS 3.16+（查看 QGIS LTR/最新版）
- Python 3.9+（QGIS 自带 Python 环境）
在 QGIS Python 控制台中使用
打开 QGIS 桌面 → 菜单「Plugins → Python Console」，即可直接使用 PyQGIS：
# QGIS 控制台中无需初始化，直接使用
layer = iface.activeLayer()
print(layer.name(), layer.featureCount())
独立脚本（Standalone Script）
在 QGIS 外部运行 Python 脚本时，需要先初始化 QGIS 应用：
import sys
from qgis.core import QgsApplication
# 初始化 QGIS（False 表示不使用 GUI）
qgs = QgsApplication([], False)
qgs.setPrefixPath("/usr", True) # Linux; Windows 示例："C:/OSGeo4W/apps/qgis"
qgs.initQgis()
# ===== 在此处编写 PyQGIS 代码 =====
# 退出
qgs.exitQgis()
独立脚本中使用 Processing
import sys
from qgis.core import QgsApplication
import processing
from processing.core.Processing import Processing
qgs = QgsApplication([], False)
qgs.setPrefixPath("/usr", True)
qgs.initQgis()
# 初始化 Processing 框架
Processing.initialize()
# 现在可以使用 processing.run()
result = processing.run("native:buffer", {
'INPUT': '/data/points.shp',
'DISTANCE': 100,
'OUTPUT': '/data/buffered.shp'
})
qgs.exitQgis()

What ships with it
2 files 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.

pyqgis is a skill published in the GitHub repository znlgis/opengis-skills (61 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 4,069 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 2026-09-03.
