Auto mode is now the default in Claude Code for Pro, Max, and Team plans

Anthropic is making auto mode the default for Claude Code on Pro, Max, and Team plans starting August 14th, citing confidence in its safety mechanisms. In a third-party evaluation by Trajectory Labs testing 720 indirect prompt injection attacks across Claude's latest models, none of the attacks succeeded. The change shifts responsibility from users approving individual actions to the model's autonomous decision-making, though questions remain about protection against sophisticated supply-chain attacks.
