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 5.1 | $0.00143 | $0.00943 |
| Opus 5 | $0.00072 | $0.00472 |
| Sonnet 5 | $0.00029 | $0.00189 |
| Haiku 4.5 | $0.00014 | $0.00094 |
Grade A, and why
maps 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 11d 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.
What it actually says
Geolonia Maps 開発ガイド
概要
Geolonia Maps は MapLibre GL JS をベースにした日本向け地図プラットフォーム。
maplibregl の全クラスが geolonia 名前空間で利用でき、HTML の data 属性による宣言的な地図埋め込みも可能。
いつ使うか（When to Use This Skill）
以下のようなリクエストで使用する:
- Geolonia Maps / Geolonia の地図をページに埋め込みたい
- 地図にマーカー・ポップアップ・GeoJSON レイヤーを表示したい
- 住所から座標を求めたい（ジオコーディング）、座標から住所を求めたい（逆ジオコーディング）、日本語住所を正規化したい
- マップスタイルを指定・切り替え・カスタマイズしたい
- MapLibre GL JS ベースで日本向けの地図機能（GSI スタイル等）を使いたい
次の場合は無理に適用しない:
- Mapbox GL JS や Google Maps など他プロバイダ固有の API に閉じた質問
- 地図と無関係な一般的な Web 実装
セットアップ（CDN）
<script type="text/javascript" src="https://cdn.geolonia.com/embed/v5/embed?geolonia-api-key=YOUR-API-KEY"></script>
- API キーは Geolonia のタイル・スタイルを使う場合に必要
- 外部の style.json を指定する場合は API キー不要
</body>の直前に配置する- 旧形式
https://cdn.geolonia.com/v1/embed?...はレガシー互換。新規実装ではembed/v5/embedを使う
基本原則
- MapLibre GL JS 互換:
maplibregl.Map→geolonia.Map、maplibregl.Marker→geolonia.Markerのように名前空間を置換するだけで全メソッド・イベントが使える - Embed API 優先: コードを書かずに HTML の data 属性だけで地図を表示できる場合は Embed API を使う
- JavaScript API: 動的な操作が必要な場合は
geolonia.Mapを使うプログラマティックな方法を使う - 日本向け最適化: GSI スタイル、日本語住所正規化、Community Geocoder など日本特有の機能が充実
リファレンス
各トピックの詳細は以下を参照:

- JavaScript API リファレンス - geolonia.Map、Marker、Popup、SimpleStyle、プラグイン
- ジオコーディング - 住所→座標、座標→住所、住所正規化
- マップスタイル - 組み込みスタイル一覧とカスタマイズ方法

公式ドキュメント
What ships with it
6 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.

maps is a skill published in the GitHub repository geolonia/geolonia-agent-skills (2 stars, last pushed 24d ago), licensed MIT. It adds 143 tokens to every session and 943 once invoked, about $0.0007 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 2026-08-31.
