Shipping an Antigravity Agent as a Paid API — Gateway Design, Usage Billing, and Enterprise Pricing from Scratch
A complete implementation guide for turning Antigravity agents into a billable API service. Covers API gateway, API key management, token tracking, Stripe Metered Billing, rate limiting, and enterprise SLA design — with production-ready code throughout.
Force Gemma 4 to Stay Inside Your Schema: A Production Guide to Constrained Decoding in Antigravity with GBNF, Outlines, and vLLM
A production-grade guide to running Gemma 4 locally in Antigravity while guaranteeing schema-compliant output. Covers llama.cpp GBNF grammars, Outlines with Pydantic, and vLLM guided_json — with concrete Python code and failure-mode fallbacks.
Implementing Antigravity's A2A Protocol — Practical Patterns for Agent-to-Agent Conversation
A hands-on guide to Antigravity's A2A (Agent-to-Agent) protocol. Walks through the minimal two-agent setup and three real-world patterns — fire-and-forget, bidirectional confirmation, and scatter-gather — with runnable samples.
SRE for Antigravity Agents — Taming Probabilistic Systems with SLOs and Error Budgets
AI agents are probabilistic by nature, so running them in production without SRE thinking is risky. This guide shows how to apply SLIs, SLOs, and error budgets to Antigravity agents with working code and concrete operational decisions.
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
A practical, code-first guide to defending LLM applications against prompt injection inside Antigravity. Covers direct, indirect, and multi-turn attacks with working Python implementations of a four-layer defense.
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 — Turning an Agent into a Project Executor
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.
