showTurnDuration Setting

New setting showTurnDuration controls whether "Cooked for Xm Xs" messages appear.

showTurnDuration is a boolean runtime setting in Claude Code 2.1.7 that toggles whether turn-duration messages ("Cooked for Xm Xs") appear in terminal output.

How It Works

The setting controls terminal verbosity for a single runtime message type. Default value is true (shows duration). Set to false in settings.json to suppress the message:

{
  "showTurnDuration": false
}

When enabled, Claude Code displays elapsed time at the end of each turn completion; when disabled, the message is omitted entirely.

What the Test Found

Status: CODE REVIEW / INCONCLUSIVE. The test (2026-01-16, version 2.1.7 features on 2.1.9) was not runtime-verified. The behavior was assessed as straightforward toggle logic and documented as expected, but no actual invocation of a prompt with the setting toggled was executed to confirm the message suppress/display behavior in practice.

Use Cases

Disabling the duration message reduces terminal noise in four scenarios: cleaner output during normal use, screencast/demo recording (timing not visible), CI pipeline logs (reduced noise), and focus modes to minimize visual distraction.

Caveats

As an unverified code review, actual runtime behavior may differ from documented expectations. The setting affects only the duration-display message, not the underlying timing calculation. Verification requires invoking a prompt in Claude Code 2.1.7+ with the setting enabled and disabled to observe presence or absence of "Cooked for" output.
