Turn
One complete response from , from your message to its finish. See what it is, how it works, how it is used and what to watch for, with pictures and examples.
What it is
A turn is one full answer from . It starts when you send a message and ends when Claude finishes responding. In between, Claude may use tools many times, for example run the tests, read the errors, edit a file and run the tests again. A session is a chain of many turns.
How it works
-
You send one message
-
Claude gathers with tools
-
Claude acts and checks results
-
Claude finishes; the turn ends
How to use it
-
Escstops Claude right away; the running is canceled and Claude waits for you.
-
Type and press
Enterwhile Claude works — your message is queued, and Claude reads it within the same turn after the current tool calls finish. -
— a hook that runs each time Claude finishes responding, for example to send a notification.
-
Commands sent during a turn — most of them and runs them after the turn ends; a few, such as
/status, run at once.
Watch out
One turn is not one tool call. A single turn can hold dozens of actions. A Stop hook does not run when you interrupt Claude yourself, and errors fire a different hook named StopFailure.
