Agent Skills for ArcGIS Maps SDK for JavaScript (SDK 5.0). 35 skills covering maps, layers, visualization, spatial analysis, widgets, editing, 3D, and more.

The simplest path works for every supported agent — use the skills CLI:

npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context

It auto-detects which coding agents you have installed and copies the skills to the correct location for each. To target a specific agent, use -a:

npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context -a claude-code
npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context -a cursor
npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context -a github-copilot
npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context -a opencode

Install individual skills instead of the full set:

npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context/arcgis-starter-app
npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context/arcgis-core-maps

Some agents ship first-party plugin marketplaces with a nicer in-agent UX than the CLI.

Register the marketplace, then install the plugin:

/plugin marketplace add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context
/plugin install arcgis-maps-sdk-js-ai-context@arcgis-maps-sdk-js-skills

Cursor 2.5+ ships a plugin marketplace and reads plugins from repos containing .cursor-plugin/plugin.json (which this repo provides). Install via Cursor Settings → Plugins → Add plugin, or browse cursor.com/marketplace. See the Cursor plugin docs for details.

If you prefer the CLI, npx skills add SaschaBrunnerCH/arcgis-maps-sdk-js-ai-context -a cursor also works.

GitHub Copilot auto-discovers skills from .github/skills/, .claude/skills/, and .agents/skills/ in your project (configurable via the chat.skillsLocations setting). Install via the Skills CLI above, or type /skills in Copilot Chat to open the Configure Skills menu.

See Use Agent Skills in VS Code for details.

Tell Codex:

Detailed docs: .opencode/INSTALL.md

Start a new session in your agent and ask it to help with an ArcGIS Maps SDK task (for example, "create a map with a FeatureLayer"). The agent should automatically use the relevant ArcGIS skill.

See skills/README.md for the full index by category.

After installing, your AI agent automatically gets ArcGIS-specific knowledge:

• Correct import patterns for ESM and Map Components
• Best practices for TypeScript with autocasting
• Code examples for common tasks
• Reference samples linking to official SDK sample code
• Common pitfalls and how to avoid them
• Cross-references between related skills

• VS Code with GitHub Copilot
• Claude / Claude Code
• Codex
• OpenCode
• Cursor
• Any agent supporting the Agent Skills specification

For Claude Code:

/plugin update arcgis-maps-sdk-js-ai-context

For Codex/OpenCode, pull the latest in the cloned directory:

git pull

For the Skills CLI, re-run the npx skills add command to get the latest version.

Skills for SDK 4.34 are preserved on the sdk-4.34 branch. That branch includes the original CLI installer:

npx @saschabrunnerch/arcgis-maps-sdk-js-ai-context skills --sdk 4.34

Skills are based on the official ArcGIS Maps SDK for JavaScript documentation:

• Documentation: https://developers.arcgis.com/javascript/latest/downloads/
• Folders used: api-reference, sample-code, and map-components

This project was primarily developed using AI coding assistants. The maintainer directed the development through prompts and reviewed all generated code.
