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 | $0.00050 | $0.06045 |
| Opus 5 | $0.00025 | $0.03023 |
| Sonnet 5 | $0.00010 | $0.01209 |
| Haiku 4.5 | $0.00005 | $0.00605 |
Grade A, and why
arcgis-starter-app 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.
How it starts
The opening of the file, as written. The whole thing — 892 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArcGIS Starter App
Use this skill to create ArcGIS Maps SDK for JavaScript applications with TypeScript and Vite. Choose between a minimal setup for quick prototyping or a production-ready configuration with full tooling.
Prerequisites
- ArcGIS account: An ArcGIS Location Platform, ArcGIS Online, or ArcGIS Enterprise account is required to access content and services.
- Access token: Create an access token through your portal with appropriate privileges (basemaps, geocoding, routing, etc.) and configure allowed referrers for production use.
- Node.js: LTS version (20+) with npm or pnpm.
Note: CSS for Map Components loads automatically when using npm — no manual CSS import for
@arcgis/map-componentsis needed. The@arcgis/coreCSS import is only required when using Core API widgets directly.
Framework Integration
React 19
Map Components are web components (custom elements). In React 19, use them directly and attach event listeners with the on prefix:
import "@arcgis/map-components/dist/components/arcgis-map";
import "@arcgis/map-components/dist/components/arcgis-zoom";
function App() {
return (
<arcgis-map
basemap="topo-vector"
center="-118.24,34.05"
zoom={12}
onarcgisViewReadyChange={(e: CustomEvent) => {
const { view } = e.detail;
console.log("View ready:", view);
}}
>
<arcgis-zoom slot="top-left"></arcgis-zoom>
</arcgis-map>
);
}
Important: Use event listeners (e.g.,
onarcgisViewReadyChange) rather than calling methods directly on the element ref, since the component may not be defined yet at render time.
Angular
Add CUSTOM_ELEMENTS_SCHEMA to your module or standalone component so Angular recognizes non-Angular elements:
import { CUSTOM_ELEMENTS_SCHEMA, Component } from "@angular/core";
@Component({
selector: "app-map",
standalone: true,
schemas: [CUSTOM_ELEMENTS_SCHEMA],
template: `
<arcgis-map basemap="topo-vector" center="-118.24,34.05" [zoom]="12">
<arcgis-zoom slot="top-left"></arcgis-zoom>
</arcgis-map>
`,
})
export class MapComponent {}
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.

arcgis-starter-app 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 50 tokens to every session and 6,045 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.
