AI agents: the week

- LangGraph – migrate existing agents to LangGraph’s stateful workflow engine for deterministic execution and built‑in human‑in‑the‑loop support. - Claude Agent SDK – adopt new 5‑level sub‑agent hierarchy and 200‑spawn limit to scale complex delegation tasks. - OpenAI Agents SDK – switch to the SDK’s MIT‑licensed tight‑scope assistants for simpler tool‑calling and easier model interchange. - Microsoft Agent Framework – integrate with Azure IAM, Pub/Sub, and BigQuery for end‑to‑end cloud‑native agent deployments. - Mastra – evaluate this TypeScript‑first framework for production agents when your stack is JavaScript/edge‑centric.
