AguiA2cuiBridge

class AguiA2cuiBridge(parser: A2uiParser = A2uiParser(), val a2uiCustomEventName: String = "a2ui")

Translation layer sitting between AguiEvents and A2CUI's own abstractions.

CopilotKit carries A2UI frames as AG-UI CUSTOM events named "a2ui", with the frame embedded in the value field. This bridge extracts those payloads and re-emits them through the standard A2uiParser path. Tool calls and state events are exposed as separate flows so apps can wire per-concern consumers.

Constructors

AguiA2cuiBridge

constructor(parser: A2uiParser = A2uiParser(), a2uiCustomEventName: String = "a2ui")

Properties

a2uiCustomEventName

val a2uiCustomEventName: String

Name matched against CUSTOM.name to detect A2UI-carrying events.

Functions

a2uiFrames

fun a2uiFrames(events: Flow<AguiEvent>): Flow<A2uiStreamEvent>

Extract A2UI frames from CUSTOM events whose name matches a2uiCustomEventName.

interrupts

fun interrupts(events: Flow<AguiEvent>): Flow<List<Interrupt>>

Filter only RUN_FINISHED events whose outcome is "interrupt" — ready to present as HITL prompts.

toolCalls

fun toolCalls(events: Flow<AguiEvent>): Flow<ToolCallEvent>

Streaming tool-call reducer: builds ToolCallEvents out of TOOL_CALL_* events.
