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 | $0.00053 | $0.03119 |
| Opus 5 | $0.00026 | $0.01559 |
| Sonnet 5 | $0.00011 | $0.00624 |
| Haiku 4.5 | $0.00005 | $0.00312 |
Grade A, and why
geometry-api-net 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 7d 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.

序列化格式
WKT（Well-Known Text）
using OpenGIS.Esri.Geometry.Core.IO;
// 导出
string wkt = WktExportOperator.ExportToWkt(geometry);
// "POINT (10.5 20.7)"
// "POINT Z (10.5 20.7 30.1)"
// "LINESTRING (0 0, 10 0, 10 10)"
// "POLYGON ((0 0, 10 0, 10 10, 0 10, 0 0))"
// "MULTIPOINT ((1 2), (3 4))"
// 导入
Geometry geometry = WktImportOperator.ImportFromWkt("POINT (10.5 20.7)");
WKB（Well-Known Binary）
// 导出（默认小端序）
byte[] wkb = WkbExportOperator.ExportToWkb(geometry);
byte[] wkb = WkbExportOperator.ExportToWkb(geometry, bigEndian: true);
// 导入（自动检测字节序）
Geometry geometry = WkbImportOperator.ImportFromWkb(wkbBytes);
GeoJSON
// 导出
string geoJson = GeoJsonExportOperator.ExportToGeoJson(geometry);
// {"type":"Point","coordinates":[10.5,20.7]}
// 导入
Geometry geometry = GeoJsonImportOperator.ImportFromGeoJson(geoJsonString);
What ships with it
1 file 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.

geometry-api-net is a skill published in the GitHub repository znlgis/opengis-skills (60 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 3,119 once invoked, about $0.0003 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.
