Designing Antigravity Browser Agents That Don't Go Flaky — Taming DOM Drift and Timing
A browser-agent task that passed yesterday trips today, then succeeds on retry, then fails again. Here's how I've been breaking down the causes of flaky Antigravity browser agents in production and addressing them at the design level.
Keeping the Antigravity Python API Stable in Production — Retries, Timeouts, and Circuit Breakers That Actually Work
A deeply practical guide to keeping Python services built on the Google Gen AI SDK alive under real traffic. We cover retry, timeout, circuit breaker, rate limit, and cost budgeting patterns with runnable code from an Antigravity workflow.
Prompt Injection Defense in Antigravity — A Production Security Playbook for LLM Apps
Build a four-layer prompt injection defense inside Antigravity with working Python. Includes measured heuristic recall across eight obfuscations and the normalization bug that breaks detection for non-Latin scripts.
Three Safeguards Every Antigravity Python API Deployment Needs Before Production
Retries, timeouts, and circuit breakers — the three production safeguards you need around your Antigravity Python API calls, with working code for each.
Running Multiple Gemma 4 LoRAs in Production — A Practical Guide to Merging and Dynamic Adapter Switching
You've trained several LoRAs on Gemma 4 — summarization, translation, code review. How do you serve them without tripling your GPU bill? A working notebook on pre-merge rank checks, Weighted and TIES merges, dynamic switching, and measuring switch churn, written with Antigravity alongside.
Fixing Antigravity Connection Errors Behind Corporate Proxies and Firewalls
Antigravity works fine at home but fails to sign in or reach the Gemini API on your office network. This guide walks through reading the logs, configuring HTTP proxies, trusting corporate CAs, and getting domain allowlisting right.
Harness Engineering for Antigravity
A deep dive into 'harness engineering' for Antigravity — the prompt-and-template design that makes an agent complete a project, not just answer a question.
Running Gemma 4 on a Self-Hosted vLLM Server from Antigravity — A Practical Guide to Building High-Throughput Inference
Gemma 4 runs beautifully in Ollama for a single user. The moment a handful of teammates start hitting the same endpoint, throughput collapses. This guide walks you through replacing Ollama with a self-hosted vLLM server, wiring it into Antigravity as a custom endpoint, choosing a quantization level with real numbers, and hardening the stack with rate limits and LoRA routing — end to end.
Prompts Are Assets: Building a Production-Grade Prompt Management Platform with Antigravity — Versioning, A/B Testing, and Quality Evaluation
A hands-on implementation guide for treating prompts as first-class code — with versioning, A/B testing, and automated quality evaluation. Design patterns and working code for running AI agents on Antigravity with safe, continuous prompt improvement.
Tuning Gemma 4 for Yourself — A Realistic LoRA / QLoRA Workflow on a Solo Developer's Budget
Full fine-tuning of Gemma 4 is out of reach for most individuals, but LoRA / QLoRA makes personalization realistic on a solo budget. This guide walks through data prep, training settings, evaluation, and wiring the result into an Antigravity workflow — from hard-earned practical experience.
Building Production-Grade Voice Agents with Gemini Live API in Antigravity — Bidirectional Audio, Screen Share, and Latency Patterns
A field guide for shipping production-ready realtime voice agents with Gemini Live API on Antigravity. Covers architecture, latency, resilience, function calling, and cost governance with working TypeScript.
Building a Business Automation Agent with Antigravity × Google Workspace API — Gmail, Drive, Sheets and Docs in Production
Learn how to build AI agents that automate Gmail responses, generate documents from Drive templates, and create intelligent Sheets reports using Antigravity, Google Workspace APIs, and Gemini.
