Demonstration

@Serializable

data class Demonstration(val input: String, val output: String, val intermediateMessages: List<Message>? = null)

A unified demonstration representing an input-output example for few-shot learning.

Demonstrations can represent either compact I/O pairs (labeled examples) or full execution traces with intermediate reasoning steps (bootstrapped examples). The intermediateMessages field distinguishes these: when present, it contains the full conversation trace from a successful subgraph execution (tool calls, assistant responses, etc.).

Constructors

Demonstration

constructor(input: String, output: String, intermediateMessages: List<Message>? = null)

Properties

input

val input: String

The example input, stringified at the subgraph boundary.

intermediateMessages

val intermediateMessages: List<Message>? = null

Optional intermediate conversation messages from the subgraph execution. When present, includes tool calls, tool results, and assistant responses that produced the output. Absent for labeled (non-bootstrapped) demonstrations.

output

val output: String

The example output, stringified at the subgraph boundary.
