Properties

afterAgentCallbacks

val afterAgentCallbacks: List<AfterAgentCallback>

List of callbacks to run after the agent executes.

beforeAgentCallbacks

val beforeAgentCallbacks: List<BeforeAgentCallback>

List of callbacks to run before the agent executes.

description

open val description: String

The description of the agent.

disallowTransferToParent

val disallowTransferToParent: Boolean = false

When true, the framework will not route the next user turn back to this agent after the parent transfers control to it; instead the next turn falls back to the root agent. Set this on utility sub-agents the parent calls and returns from (translators, summarizers, classifiers). Leave at the default false for sub-agents that should keep handling follow-up turns directly (e.g. billing, support).

disallowTransferToPeers

val disallowTransferToPeers: Boolean = false

When true, prevents this agent from transferring sideways to a peer agent under the same parent. Typically set together with disallowTransferToParent on one-shot utility agents. Violations are surfaced by the runner as IllegalArgumentException.

name

val name: String

The name of the agent.

subAgents

val subAgents: List<BaseAgent>

List of sub-agents.

Functions

findAgent

fun BaseAgent.findAgent(targetName: String): BaseAgent?

Finds an agent with the given name in this agent's subtree (including itself).

runAsync

fun runAsync(parentContext: InvocationContext): Flow<Event>

Public entry point for executing the agent asynchronously (text-based).
