Loop keepalive is on by default

Self-paced loops now keep going until the budget is spent instead of stopping early.

What

Loops that let the model set its own pace now keep rescheduling by default. The gate tengu_kairos_loop_keepalive ships with a built-in default of on (it was off), and the per-schedule check that bailed out early has been removed, so a loop runs until the budget is spent rather than stopping at the gate.

Details
  • Rescheduling goes straight to the budget check, which ends the loop with "keepalive budget exhausted (model declined to reschedule twice) — ending loop".
  • CLAUDE_CODE_LOOP_KEEPALIVE overrides both the server value and the built-in default.
  • With no server value set, keepalive is live on this build.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on Common workflows touched a line naming /loop after this was published. | [`/loop`](/docs/en/scheduled-tasks) | The current CLI session | Quick polling while a session is open. `--resume` and `--continue` restore unexpired fixed-interval loops. | common-workflows see the edit
Confirmed since Anthropic's documentation has since written up /loop, on Schedule recurring tasks in Claude Code Desktop. | | [Cloud](/docs/en/routines) | [Desktop](/docs/en/desktop-scheduled-tasks) | [`/loop`](/docs/en/scheduled-tasks) | desktop-scheduled-tasks see the edit
