Antigravity × Multi-Provider LLM Failover — A Production Guide for Gemini, Claude, and Local Gemma
When Gemini returns 503, does your agent stop responding? This guide walks through a production-ready router, circuit breaker, and graded fallback design, with code you can paste in today.
Production Multi-Agent Systems with Antigravity AgentKit 2.0: Patterns, Failure Modes, and What the Demos Don't Show
AgentKit 2.0 makes multi-agent systems look effortless in demos, but running them in production is a different problem. This guide covers Planning vs. Fast mode, three real orchestration patterns, and the failure modes — infinite loops, cost blowouts, prompt injection — that bite on day one.
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.
Build a CSV Analysis Agent in Antigravity with pandas and Matplotlib
Walk through building an Antigravity agent that analyzes CSV files from natural-language instructions. Covers the pandas tool design, common pitfalls, and safety practices for production use.
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.
Diagnosing and Stopping Runaway Agent Loops in Antigravity
Build agents with Antigravity and you will eventually meet the 'same tool called twenty times in a row' problem. Here is how to classify the failure mode and stop it at the implementation level.
Antigravity Walkthrough Won't Load? A Field Guide to Fixing Empty or Frozen Panels
Your Walkthrough panel is blank, stuck on loading, or showing old data. Here's how to diagnose the real cause — cache, sync, or network — and get it working again.
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.
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.
Antigravity Background Agent in Production — Task Specs, git worktree Parallelism, and the Interactions API
From the sandbox VM to task specifications, AGENTS.md, git worktree parallelism, CI/CD wiring through the Interactions API, and realistic cost estimates — including the mistakes that shaped each one.
Antigravity AI Agent Design: Multimodal Production Implementation Patterns
A complete guide to building multimodal AI agents with Google Antigravity (Gemma 4). Covers image+text integration, Function Calling, async batch processing, state management, error handling, and cost estimation — with production-ready code.
AI Agent Memory Design: 4 Patterns for Context That Persists Beyond a Single Conversation
A practical breakdown of four memory architectures for AI agents — from in-session compression to episodic storage — with implementation code and the gotchas that only show up in production.
