- Summary: Anthropic states in a post dated 2026-08-07 that starting 2026-08-14 new sessions on Pro, Max, and Team plans run in auto mode, the permission mode in which a classifier decides which commands run without a prompt. A user who set a different default may get a one-time prompt, and a pinned default is unchanged. The announcement cites a controlled study in which human review of prompts detected a planted dangerous command 13.6 percent of the time against 89 percent for the classifier.
- Why it matters: The permission model most Claude Code sessions run under changes on a fixed date, so teams that rely on per-command prompts have until 2026-08-14 to pin the mode explicitly.
- Follow-up: Confirm the rollout on 2026-08-14.
