AgentCore CLI Reaches GA with Multi-Framework Scaffolding Including Google ADK and OpenAI Agents

Full analysis

The AgentCore CLI reached general availability at v0.4.0 in March 2026, providing a command-line tool for scaffolding, developing, and deploying AI agents. It supports multiple agent frameworks at project creation — Strands, LangChain, Google ADK (Agent Development Kit), and OpenAI Agents — with local development including hot reload, and full infrastructure management for production deployment. An Agent Inspector UI, launched in April, adds a browser-based interface for inspecting token usage, tool calls, execution traces, and deployed memory during local development.
