turn/interrupt

Stops the running turn on the runtime’s priority lane, optionally pairing a durable retract intent.

Parameters

Type: TurnInterruptParams

turn/interrupt params: the “user pressed stop” gesture, on the runtime’s priority lane.

Field	Type	Stability	Presence	Description
commandId	string		required	The idempotency handle (UUIDv7).
retract	boolean		optional	Pair a retract intent with the interrupt: if the turn is cancelled before any assistant output committed, the submission is durably retracted (view event turn/retracted) so the client may restore the prompt text. A rejected retract does not undo the interrupt. Default false.
sessionId	string		required	The target session.
turnId	string		optional	The exact turn to interrupt. Omit to target the session’s current foreground turn, resolved at admission; prefer passing the explicit id when you have one.
