Gemini CLI Ships Subagents: Google's CLI Now Orchestrates Parallel Specialized Agents with Isolated Context Windows

Google Developers Blog·high signal

Google announced on April 15, 2026 that subagents have arrived in Gemini CLI. Each subagent operates within its own separate context window, custom system instructions, and curated tool set, keeping the main session lean while delegating sub-tasks. Parallel execution lets you dispatch multiple agents simultaneously — research five topics or refactor several components at once. Built-in subagents include Codebase Investigator (dependency mapping), CLI Help Agent, and an experimental Browser Agent. This positions Gemini CLI as a direct competitor to Claude Code's subagent architecture.
