Antigravity the Ralph Wiggum style

 The [Ralph Wiggum trend](https://ghuntley.com/ralph/) has been surfacing across social platforms lately. If you're tracking current tech developments, it’s hard to miss. Named after a persistent and slightly confused second-grader, the Wiggum Loop agentic development boils down to: **Don't stop until the job is done.** In traditional AI coding, the agent performs a task, stops, and waits for you to approve its next step or request changes. In a Wiggum Loop, you give the agent a mission and success criteria (like passing tests), and it keeps looping, fixing its own bugs and refactoring - until it hits the green light. The recent excitement around the Wiggum Loop agentic development highlights a powerful shift: achieving autonomous, self-correcting development. I've been leveraging a similar approach effectively with [Antigravity](http://antigravity.google) for some time already. In this post, I’ll share my strategy, enabling you to implement true unsupervised development yourself. ## Going "Full Wiggum" To achieve true unsupervised development, we need to move away from the review-driven defaults and let the agent take the wheel. Antigravity is uniquely built for this because it's an agent-first environment capable of acting in both the terminal and the browser. To mirror the “Bash loop" persistence of the Ralph Wiggum plugin, configure your [Antigravity settings](https://antigravity.google/docs/agent-modes-settings) as follows: 1. **Mode:** Select Agent-driven development. This shifts the agent from a "wait for instructions" assistant to a "goal-oriented" architect. 2. **Terminal execution policy:** Set to Always Proceed. This allows the agent to run `npm test`, `uv run pytests`, and other commands without constantly pausing for approval. 3. **Review policy:** Set to Always Proceed. This tells the agent that its implementation plans are pre-approved. 4. **JavaScript execution policy:** Set to Always Proceed. This is essential for agents that need to run scripts or interact with browser environments to verify their work.  > **WARNING: THE SANDBOX IS NOT OPTIONAL.** Running an agent in "Always Proceed" mode is like giving Bart Simpson a slingshot in front of a mirror store. **Only do this in a sandbox environment.** > Here is [a great article](https://medium.com/google-cloud/using-chrome-remote-desktop-to-run-antigravity-on-a-cloud-workstation-or-just-in-a-container-d00296425a0f) from my [colleague](https://medium.com/@danistrebel) which shows a step-by-step guide to setting such an environment up and running on [Cloud Workstation](https://cloud.google.com/workstations?utm_campaign=CDR_0x87fa8d40_default_b478855277&utm_medium=external&utm_source=blog). ## Example To see this in practice, I ran the following prompt against Antigravity: ``` Build a REST API for todos in NodeJS. When complete: - All CRUD endpoints are working - Input validation is in place - Tests are passing (coverage > 80%) - README with API docs exists ``` The screencast below shows how Antigravity handled the task without my interruptions (I spent this time on other tasks rather than handholding the agent): {% embed https://www.youtube.com/watch?v=HLLCn4KsNcc %} ## How does this work? Antigravity isn't just looping in a vacuum. Because it has native hooks into [Gemini 3 Pro](https://docs.cloud.google.com/vertex-ai/generative-ai/docs/start/get-started-with-gemini-3?utm_campaign=CDR_0x87fa8d40_default_b478855277&utm_medium=external&utm_source=blog), it utilizes a massive context window that remembers exactly why a previous command failed. It kicks things off by drafting up an implementation plan and a task list. In the video, you can watch it tick through these items in real time. It doesn't just plan, though - it actually touches the terminal to initialize the npm project and run tests. The loop only closes once every requirement is met and the test suite hits green. It then provides a handy walkthrough so you can easily understand the architecture it just spun up. This approach turns development from writing code into verifying outcomes. ## From vibe-coding to vibe-building The Ralph Wiggum trend isn't about cutting corners; it's about embracing sheer, stubborn persistence through automation. By letting Antigravity operate autonomously, you transition from a coder to an architect and team lead. You define the standards and environment, while agents manage the iterative grind of writing, testing, and debugging cycles that typically consume a developer's valuable time. Are you brave enough to let the agent "Always Proceed"?
