## Ask an agent to

-   Explain which data sources are stale for this area
-   Draft a situation report for the selected area

## 11 tools

    Explain ready, empty, unavailable, stale, and modelled source coverage without inventing a risk score.

-   `focus_place`
    
    Resolve a worldwide place name with ArcGIS, visibly move the shared investigation area, and refresh environmental evidence.
    
    query: string, radiusKm: number?
    
-   `get_workspace_state`
    
    Inspect the current shared Earth Lens area, time window, visible layers, source states, evidence, and revision.

    latitude: number, longitude: number, radiusKm: number, label: string?

    Show or hide one environmental evidence layer on the shared map.
    
    layerId: string, visible: boolean

    Change the shared evidence time window and visibly refresh time-dependent sources.
