Gemini-CLI, Jules, Antigravity
Gemini CLI on Windows (no sandbox) - sure it's not a straightforward task. That's why I use GenAI in the first place. To get grindy things done.

Gemini-CLI, Jules, Antigravity

Google announced new tools, and they look promising for coders and creatives alike. GenAI meets automation. Arts meets tech. Let's go.

Recently news spread about Anthropic abandoning their flagship innovation product claude-code.

claude-code epilepsy warning: Do not use in production. And how to stay healthy
Screen flickering with `claude-code`? Headaches from erratic scrolling bugs? Dizzy? This can help you. Stay healthy with a workaround.

Apparently they saw that they don't have a chance. Google decided to take the business instead. Better late than never.

Gemini-CLI

gemini is a helpful command-line center for context engineering in software development. It can also help with documents, btw..

Gemini models allow for super-large context, but the CLI may need a lot of memory. The CLI uses cache to save tokens. Gets the job done.
  • Gemini CLI has different scrolling and scrollback modes for my use cases. Something claude code failed to deliver for months.
    • Integrated terminal buffers
    • It's also open-source, meaning if you need to fix something, you can get it fixed (with AI)
  • The new Gemini 3 model is likely going to rival Sonnet
    • available for 20 to 100 EUR / USD
    • I have been making good experiences with it so far since yesterday
  • I didn't find "claude skills" to be useful, but gemini has
    • extensions for prompts
    • MCP support for context7 and what you may need
    • Obviously it supports Chrome Dev Tools, come on... Google tools working with Google software
    • Memory / user instructions support is good when you move from Opus / Sonnet to Gemini 3
  • Gemini CLI can run in a Sandbox
    • Meaning: you don't have to expose your computer
  • Gemini CLI works on Microsoft Windows
    • It can be instructed to use PowerShell and not WSL (!)

There is no Gemini Desktop app, which could bring MCP to the hands of non-tech folks. But there is an agentic framework you can use. Or an unofficial app or two.

Use MCP servers with Gemini 3 Web / Deep Research / Deep Think / RAGflow with DSPy
Fellow researchers and knowledge seekers, today I have a special trick. The most powerful research tool you have ever had. 1. Gemini 3 (Model Card) - available via a subscription 2. RAGflow with my RAGflow MCP server (GitHub) 1. using a custom knowledge base (Quant Literature) 3. MCP server availability

Personally, I can see myself using the CLI for MCP-aided R&D work. Or the browser extension.

Jules

Jules is an autonomous code (cleanup) tool. It handles the tasks that you don't want to do. Time is money.

  • Update documentation
  • Clean up leftover files
  • Fix smaller build errors
  • Update dependencies
Jules works for 1-2 hours, slowly, slowly, and then makes a PR. You run your test suite via CI and merge it. Ty Jules!

Jules comes as a bonus on top. It can work the night shift, go through Dependabot and CodeQL alerts, check SemGrep issues, etc., etc.

It works in a (random included Google) VM and does not need your computer(s). I am new to this, but you can make instructions to make it autonomous.

There is a learning curve, especially with the CI and GitOps (test envs) part. I can see a ZTNA test env workflow here, where Jules warms up a testbed before I come to the office. And I define minimum access criteria and one-time keys for the low-end tasks.

Antigravity

Antigravity is another addition. It's just a Visual Studio Code fork. But it has two key features:

  1. Focused on automation with Gemini models ("agentic" flows)
    1. can instantiate multiple agents with different objectives
    2. this seems well-done: the agents do what they are supposed to do, and they actually follow the instructions
  2. It doesn't cost extra
Antigravity is like Cursor or Windsurf, but it has the edge when it comes to coordinating agents. Other than that, it is plain, simple VS Code.

On Windows, check out

  • %USERPROFILE%\AppData\Local\Programs\Antigravity\bin for the antigravity cmd
  • On macOS it's agy

These are the pendants to code to open folders. Or cursor if you still remember it.

Summary

My rating of the Gemini productivity suite: 8/10.

Plus points:

  • Powerful new tools
  • Powerful models
    • Gemini 3 benchmarks are not all I look at
  • Rich Web UI
  • Deep Research and Deep Think
  • YT Premium bonus
  • NotebookLM
    • instead of watching YT videos in full length, just move to Deep Research and take notes into your workflows
  • Code Wiki (internal for custom repositories)
  • ...

Minus points:

  • cost model is weird, because Google One Ultra comes with a creative suite of video and image editing models.
    • That is fun to use, if you can afford it.
      • these creative tools do not produce project files for video or image editors (!)
    • For the 20 bucks upfront, you will need to switch from subscriptions to the API keys
      • this feels complicated, tbh.
  • lack of MCP support for Desktop apps (!)
    • power remains hidden

Maybe the next big thing will come from China. 😃
