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 | $0.00044 | $0.04365 |
| Opus 5 | $0.00022 | $0.02183 |
| Sonnet 5 | $0.00009 | $0.00873 |
| Haiku 4.5 | $0.00004 | $0.00436 |
Grade A, and why
arcgis-widgets-ui 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 — 609 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArcGIS Widgets & UI
Use this skill when building user interfaces with widgets, Map Components, and Calcite.
Best Practice: Prefer Map Components (web components like
arcgis-legend,arcgis-search) over Core API widgets. Esri has transitioned to web components as the primary approach.
Import Patterns
Map Components (ESM)
import "@arcgis/map-components/dist/components/arcgis-map";
import "@arcgis/map-components/dist/components/arcgis-legend";
import "@arcgis/map-components/dist/components/arcgis-search";
import "@arcgis/map-components/dist/components/arcgis-layer-list";
import "@arcgis/map-components/dist/components/arcgis-expand";
Core API Widgets (ESM)
import Legend from "@arcgis/core/widgets/Legend.js";
import LayerList from "@arcgis/core/widgets/LayerList.js";
import Search from "@arcgis/core/widgets/Search.js";
import BasemapGallery from "@arcgis/core/widgets/BasemapGallery.js";
Dynamic Imports (CDN)
const Legend = await $arcgis.import("@arcgis/core/widgets/Legend.js");
const Search = await $arcgis.import("@arcgis/core/widgets/Search.js");
Note: CSS for Map Components loads automatically via npm. Core API widgets require:
@import "@arcgis/core/assets/esri/themes/light/main.css";

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-widgets-ui 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 44 tokens to every session and 4,365 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.
