Subagents in Gemini CLI

What it does

Gemini CLI's new subagents feature lets the main agent delegate complex tasks to specialised agents, each with isolated context, custom tools, and scoped permissions. For developers building or automating from the terminal.

Learn how subagents in Gemini CLI act as specialized experts to handle complex, high-volume tasks in isolated context windows. This new feature enables parallel execution, reduces context rot, and allows for custom agent definitions using simple Markdown and YAML.

Subagents allow Gemini CLI to delegate complex, repetitive, or high-volume tasks to specialized expert agents. Each subagent operates within its own separate context window , custom system instructions, and curated set of tools. This keeps your main session fast, lean, and focused on the big picture while intermediate steps are handed off to a team of subagents. Subagents are specialized, expert agents that operate alongside your primary Gemini CLI session. When you give Gemini CLI a broad or complex task, it acts as a strategic orchestrator, delegating specific sub-tasks to the most relevant subagent . Subagents act in isolation with their own set of tools , MCP servers , system…from developers.googleblog.com

  A simple weekend project, to check if chat conversation could be used on CLI. Uses Google Gemini's gemini-2.0-flash model. Configs will make it nicer, but I wanted to keep it simple to test and launch for now. I can add things for you :) Please give it a try!

  OSS Agent I built topped the TerminalBench on Gemini-3-flash-previewApr 2026 · github.com · ▲393

  Scored 65.2% vs google's official 47.8%, and the existing top closed source model Junie CLI's 64.3%. Since there are a lot of reports of deliberate cheating on TerminalBench 2.0 lately (https://debugml.github.io/cheating-agents/), I would like to also clarify a few things 1. Absolutely no {agents/skills}.md files were inserted at any point. No cheating mechanisms whatsoever 2. The cli agent was run in leaderboard compliant way (no modification of resources or timeouts) 3. The full terminal bench run was done using the fully open source version of the agent, no…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
