Google just open-sourced agents-cli.
Google has open-sourced agents-cli, a command-line tool that turns coding agents like Claude Code, GeminiCLI, and OpenAI's CodexCLI into full agent engineers. With a single setup command, these agents gain the ability to scaffold projects, write ADK Python code, run evaluations, and deploy to Cloud Run — enabling a single natural language prompt to build and deploy a complete agent.
