What problem does it solve? Managing ArcGIS Online and Enterprise Portal content through a CLI involves ambiguous title-based lookups, persisted selections that can point at the wrong item, silent failures hidden behind zero exit codes, and destructive operations that never prompt. This Skill provides a safe, explicit workflow for authenticating, discovering, inspecting, sharing, exporting, and modifying Portal items without accidental mutations. ## Core Features & Use Cases - Portal configuration and authentication: Add, switch, and remove Portal aliases, manage cached tokens, and control persisted per-type item selections safely. - Item discovery and management: Search items by title, tags, or owner, resolve them to 32-character item IDs, inspect metadata and resources, share with explicit levels, and delete with verification. - Feature Layer and Web Map operations: Copy, clone, and export Feature Layers with tracked jobs, manage cache and multiscale settings, inspect Web Maps, and create ArcGIS Play documents with privacy safeguards. - Use Case: You need to export layer 0 from a private Feature Layer in your production Portal to GeoJSON. The Skill guides you to resolve the item ID explicitly, start the export with a title and parameters JSON, track the local job, and verify job content rather than trusting the exit code. ## Quick Start Ask the assistant to list your hosted Feature Layers in a specific Portal alias and inspect five sample features from the one you name.
