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 | $0.04071 |
| Opus 5 | $0.00022 | $0.02035 |
| Sonnet 5 | $0.00009 | $0.00814 |
| Haiku 4.5 | $0.00004 | $0.00407 |
Grade A, and why
arcgis-visualization 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 10d 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 — 670 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ArcGIS Visualization
Use this skill when styling layers with renderers, symbols, visual variables, labels, and effects.
Import Patterns
Direct ESM Imports
import SimpleRenderer from "@arcgis/core/renderers/SimpleRenderer.js";
import UniqueValueRenderer from "@arcgis/core/renderers/UniqueValueRenderer.js";
import ClassBreaksRenderer from "@arcgis/core/renderers/ClassBreaksRenderer.js";
import SimpleMarkerSymbol from "@arcgis/core/symbols/SimpleMarkerSymbol.js";
import SimpleLineSymbol from "@arcgis/core/symbols/SimpleLineSymbol.js";
import SimpleFillSymbol from "@arcgis/core/symbols/SimpleFillSymbol.js";
CDN Dynamic Imports
const [SimpleRenderer, SimpleMarkerSymbol] = await $arcgis.import([
"@arcgis/core/renderers/SimpleRenderer.js",
"@arcgis/core/symbols/SimpleMarkerSymbol.js",
]);
Note: Examples below use autocasting (plain objects with
type). For CDN usage, replaceimport X from "path"withconst X = await $arcgis.import("path").
Renderer Types Overview
| Renderer | Autocast Type | Use Case |
|---|---|---|
| SimpleRenderer | "simple" |
Same symbol for all features |
| UniqueValueRenderer | "unique-value" |
Different symbols by category |
| ClassBreaksRenderer | "class-breaks" |
Different symbols by numeric ranges |
| HeatmapRenderer | "heatmap" |
Density visualization (points only) |
| DotDensityRenderer | "dot-density" |
Dot density maps (polygons only) |
| PieChartRenderer | "pie-chart" |
Pie charts per feature |
| DictionaryRenderer | "dictionary" |
Military symbology (MIL-STD-2525) |
| FlowRenderer | "flow" |
Animated flow lines (imagery) |
SimpleRenderer
const renderer = {
type: "simple",
symbol: {
type: "simple-marker",
color: "blue",
size: 8,
outline: {
color: "white",
width: 1,
},
},
};
layer.renderer = renderer;
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-visualization 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 4,071 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.
