Details
The Claude Code v2.1.211 update adds key features for agent workflows.
The main updates are as follows:
- Subagent data streaming: The
--forward-subagent-textflag and theCLAUDE_CODE_FORWARD_SUBAGENT_TEXTenvironment variable allow subagent text and thinking process to be included in thestream-jsonoutput. This makes debugging easier for CI, SDK, and observability workflows. - Model and permission management: Model override settings are now preserved when resuming subagents, and 'Always allow' permission rules are stored at the repository root so they persist across Git worktrees.
- Stability and compatibility improvements: Stability of MCP (Model Context Protocol) servers has been enhanced, and prompt caching and model selection have been optimized for various providers including Bedrock, Vertex, Mantle, and Foundry.
