    Interface EntityCopilotProps

    entity-copilot.tsx — EntityCopilot: a compact "sidebar copilot" variant.

    Unlike EntityChat (which renders a full chat surface), EntityCopilot is designed to be embedded inline — a floating panel, a slide-over, or an editor drawer. It reuses useChatSession for the same entity-graph projection while providing a narrower component API and a more compact default UI.

    Layering: Component → useChatSession hook → applyAgUiSnapshot/Delta (store).

    interface EntityCopilotProps {
        className?: string;
        mappings?: AgUiStateMapping[];
        onClose?: () => void;
        onError?: (error: Error) => void;
        onMessage?: (message: ChatMessage) => void;
        open?: boolean;
        placeholder?: string;
        renderSuggestion?: (message: ChatMessage, index: number) => ReactNode;
        sessionId?: string;
        streamFactory: (
            messages: ChatMessage[],
        ) => AsyncIterable<StreamEvent, any, any> | ReadableStream<StreamEvent>;
        suggestions?: string[];
        title?: string;
        toolProvider?: EntityToolProvider;
    }
