Anthropic has released Claude Code v2.1.158, which introduces classifier-gated execution, also known as auto mode, to AWS Bedrock, Google Vertex AI, and Azure Foundry. This update allows provably safe operations to proceed without user prompts, while clearly risky actions are blocked. The release is part of a rapid series of updates, including the default use of Opus 4.8 and a plugin system overhaul. Users are advised to upgrade to v2.1.158 and migrate away from a deprecated fast mode override before June 1, 2026. AI
IMPACT Enhances safety and automation for code generation tools integrated into major cloud AI platforms.
