Subagents have arrived in Gemini CLI

Gemini CLI now supports subagents, specialized agents that handle complex tasks within their own isolated context windows, tools, and system instructions while keeping the main session focused and efficient.

• •Subagents operate independently with dedicated context windows, custom tools, and instructions, consolidating their execution into a single response to prevent context pollution
• •Custom subagents can be created using Markdown files with YAML frontmatter, defined globally in ~/.gemini/agents or at project level in .gemini/agents
• •Gemini CLI supports parallel execution of multiple subagents simultaneously, useful for research, code exploration, and analysis tasks
• •Built-in subagents include generalist for general-purpose tasks, cli_help for CLI documentation queries, and codebase_investigator for code analysis
