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 | $0.00039 | $0.02863 |
| Opus 5 | $0.00019 | $0.01432 |
| Sonnet 5 | $0.00008 | $0.00573 |
| Haiku 4.5 | $0.00004 | $0.00286 |
Grade A, and why
arcgis-portal-content 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 12d 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 — 501 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArcGIS Portal Content
Use this skill for saving maps, managing bookmarks, slides, working with portal items, and configuring WebMap/WebScene structure.
Import Patterns
Direct ESM Imports
import WebMap from "@arcgis/core/WebMap.js";
import WebScene from "@arcgis/core/WebScene.js";
import Portal from "@arcgis/core/portal/Portal.js";
import PortalItem from "@arcgis/core/portal/PortalItem.js";
import PortalQueryParams from "@arcgis/core/portal/PortalQueryParams.js";
Dynamic Imports (CDN)
const WebMap = await $arcgis.import("@arcgis/core/WebMap.js");
const Portal = await $arcgis.import("@arcgis/core/portal/Portal.js");
const [PortalItem, PortalQueryParams] = await $arcgis.import([
"@arcgis/core/portal/PortalItem.js",
"@arcgis/core/portal/PortalQueryParams.js",
]);
WebMap Structure
WebMap Properties
import WebMap from "@arcgis/core/WebMap.js";
const webMap = new WebMap({
// From portal item
portalItem: {
id: "WEBMAP_ID",
portal: { url: "https://www.arcgis.com" },
},
});
// Or create from scratch
const webMap = new WebMap({
basemap: "topo-vector",
ground: "world-elevation",
layers: [featureLayer, graphicsLayer],
tables: [tableLayer],
initialViewProperties: {
center: [-118.805, 34.027],
zoom: 13,
},
bookmarks: [bookmark1, bookmark2],
});
WebMap from JSON
const webMap = WebMap.fromJSON({
operationalLayers: [
{
id: "layer1",
layerType: "ArcGISFeatureLayer",
url: "https://services.arcgis.com/.../FeatureServer/0",
title: "My Layer",
visibility: true,
opacity: 1,
},
],
baseMap: {
baseMapLayers: [
{
id: "basemap",
layerType: "VectorTileLayer",
styleUrl:
"https://basemaps-api.arcgis.com/arcgis/rest/services/styles/v2/styles/arcgis/topographic",
},
],
title: "Topographic",
},
initialState: {
viewpoint: {
targetGeometry: {
xmin: -118.9,
ymin: 33.8,
xmax: -118.1,
ymax: 34.3,
spatialReference: { wkid: 4326 },
},
},
},
});
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.

arcgis-portal-content is a skill published in the GitHub repository SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context (22 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 2,863 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.
