Interface ChainToolInput

Deprecated

Wrap in a DynamicTool instead. Interface for the input parameters of the ChainTool constructor. Extends the DynamicToolInput interface, replacing the 'func' property with a 'chain' property.

interface ChainToolInput {
    callbacks?: Callbacks;
    chain: BaseChain<ChainValues, ChainValues>;
    defaultConfig?: ToolRunnableConfig<Record<string, any>>;
    description: string;
    metadata?: Record<string, unknown>;
    name: string;
    responseFormat?: string;
    returnDirect?: boolean;
    tags?: string[];
    verbose?: boolean;
    verboseParsingErrors?: boolean;
}
