Anthropic expanded Claude SDK with mounted memory stores (Python, TypeScript, Go), redesigned session viewer with timeline minimap and cost tracking, and added Playground to Claude Console with full Messages API support. Builders can now inspect per-tool statistics, thread activity, and resource usage—critical for debugging agentic workflows and controlling inference spend at scale.

Google Antigravity launched IDE extensions for VS Code, Visual Studio, JetBrains, and Zed Editor, bringing multi-agent tools and agentic conversation directly into top editors. This closes the gap between local development and orchestrated agent workflows—developers no longer need separate platforms to compose and test multi-agent behavior.

GitHub released Copilot SDK, exposing the Copilot CLI's production-tested agent runtime for programmatic invocation without custom orchestration. Developers define agent behavior; Copilot handles planning and tool invocation—lowering friction for teams embedding agent logic into internal tools and applications.

Anthropic optimized Claude Code's self-hosted runner by removing unnecessary tree rewrites and eliminating blocking server round trips during session launch; fixed apps gateway error forwarding for 400/413 errors from Vertex, Foundry, and AWS upstreams. Lower latency and clearer error messages reduce friction for teams running Claude Code in production CI/CD and deployment pipelines.
