Subagents have arrived in Gemini CLI- Google Developers Blog

Introduces the concept of 'subagents' within the Gemini CLI, which are specialized AI agents that can be delegated complex tasks. Subagents operate with isolated context windows, system instructions, and toolsets. This design aims to improve efficiency, reduce context rot, and enable parallel execution of tasks. The post details how to define custom subagents using Markdown files and provides examples of built-in subagents like 'frontend-specialist', 'generalist', 'cli_help', and 'codebase_investigator'. It also explains explicit delegation using the '@agent' syntax and discusses the implications of parallel subagent execution.
