Anthropic Enables Auto Mode For Claude Code

Anthropic PBC announced on March 24, 2026 that it is launching "auto mode" for Claude Code, allowing the coding assistant to autonomously decide permissions for file writes and bash commands. The research-preview feature applies internal safety classifiers to approve or block each action and checks for prompt-injection attacks, and will initially roll out to Enterprise and API users on Claude Sonnet 4.6 and Opus 4.6. Anthropic recommends using auto mode only in sandboxed environments to limit potential damage.
