esri/arcgis-developer-core
Plan ArcGIS application development, clarify requirements, route to relevant developer skills, and follow ArcGIS authentication patterns using the MCP server and official documentation when available.
Use when designing ArcGIS applications, selecting ArcGIS products, or choosing and implementing API key, user, or app authentication based on app audience, ArcGIS foundational product, and resources and operations the app uses.
MANDATORY - use before planning, building, or redesigning an ArcGIS application, including requests that do not specify an ArcGIS technology. For existing applications, use when a change could affect architecture, product, technology, data access, or authentication. Review context, clarify consequential unknowns, and route to relevant authentication and build skills.
