Summary
Google added subagents to Gemini CLI so the main session can delegate isolated tasks with separate tools, MCP servers, and context windows.
What changed
Gemini CLI can now hand complex or repetitive tasks to specialized subagents that run with their own instructions, tools, MCP servers, and context windows.
Why it matters
Subagent orchestration is quickly becoming a baseline expectation for coding and agent tooling.
