Body

application/json

Send a message to a session. If the session is busy the message waits on the queue and runs as the next turn; if idle it runs immediately.

Set interrupt to make it take effect now: the session's active run is cancelled and this message drains straight after. Interrupt is a no-op when the session is already idle, and BEST-EFFORT when busy — if the cancel can't be delivered, the message stays queued and runs after the current turn.
