Method Details

input

public DecisionRequest.Builder input(String text)

Sets the input to evaluate as text. Replaces any input set before.

public DecisionRequest.Builder inputFields(Map<String,?> fields)

Sets the input to evaluate as named fields, for example Map.of("ticket", ticket, "plan", "enterprise"). See FieldsInput for the supported values. Replaces any input set before.

Since:

1.23.0

inputContents

public DecisionRequest.Builder inputContents(List<? extends Content> contents)

Sets the input to evaluate as a list of contents, for example a TextContent and an ImageContent. Which kinds of contents are supported depends on the decision model. Replaces any input set before.

Since:

1.23.0

inputMessages

public DecisionRequest.Builder inputMessages(List<? extends ChatMessage> messages)

Sets the input to evaluate as a conversation: messages in the order they were exchanged, for example a chat between a user and an AI assistant, including the tools the assistant called (AiMessage.toolExecutionRequests()) and their results (ToolExecutionResultMessage). This lets you ask questions about the whole conversation, for example whether the assistant answered the user's question, or whether a tool call is safe to execute. Messages and tool results can contain text written to influence the decision (prompt injection): do not rely on a decision alone to allow a dangerous action. Which kinds of messages and contents are supported depends on the decision model. Replaces any input set before.
