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.

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 | $0.00049 | $0.03247 |
| Opus 5 | $0.00024 | $0.01623 |
| Sonnet 5 | $0.00010 | $0.00649 |
| Haiku 4.5 | $0.00005 | $0.00325 |
Grade A, and why
geometry-api-java 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 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.
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 — 374 lines — stays where its author put it; the contents beside it link to each section on GitHub.

概述
Esri Geometry API for Java 是一个自包含的空间几何计算库，提供对二维和三维几何对象的创建、解析、序列化以及空间关系运算能力。它无需任何外部 GIS 依赖，可直接嵌入 Java 应用、Hadoop MapReduce、Hive UDF、Spark 等大数据处理框架中。

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-java is a skill published in the GitHub repository znlgis/opengis-skills (58 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 3,247 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.
