Designing Knowledge Freshness for Antigravity AI Agents — A Runtime Architecture for Model Cutoffs, Corpus Staleness, and Real-World Time Drift
Antigravity agents have to juggle three independent time axes — model cutoff, RAG corpus update, real-world clock — or they will confidently cite six-month-old documentation. Here is the runtime architecture I use, with working TypeScript code and the TTL thresholds I run in production.
Letting Antigravity Background Agent Watch the First 72 Hours After Release: A Monitoring Pipeline Forged Across Six Wallpaper Apps
Drawing on twelve years of indie iOS and Android development and six wallpaper apps released in parallel, this article shares a release-monitoring workflow built on Antigravity Background Agent. It covers how to collapse Firebase Analytics, Crashlytics, and AdMob into one Markdown report, with the actual queries and thresholds used in production.
Prompt Caching and Context Strategy for Antigravity Agents — Cutting 60-80% Off Monthly API Costs in Long-Running Production
The longer you keep agents running, the more the monthly invoice quietly piles up. Running Antigravity agents alongside an AdMob-monetized indie app business (50M cumulative downloads), I managed to cut API costs by 60-80% by rebuilding prompt caching and context strategy. This article shares the three-layer cache, context compression, and TTL design I now run in production — with the code and numbers behind them.
Running AdMob and AppLovin MAX side by side with an Antigravity sub-agent that compares them daily
For the past two months I have been running my wallpaper apps on both AdMob and AppLovin MAX in parallel, and letting Antigravity sub-agents pull eCPM, fill rate and ARPDAU into a single daily comparison. This is an implementation memo from those 90 days, focused on cross-network normalisation and the thresholds I trust an agent with.
Weekly Picks: Top 5 Must-Read Articles on Antigravity Lab (May 12 – May 18)
A roundup of the five most-read articles on Antigravity Lab from May 12 to May 18, 2026 — covering handing a ten-year-old wallpaper app to Antigravity for refactoring, a six-week maintenance report on a 50M-download portfolio, multi-agent Crashlytics triage, two weeks of Browser Sub-Agent for AdMob mediation, and the delegation boundary problem for indie developers.
When Antigravity's AI rewrites your package.json dependencies and breaks the build
You asked Antigravity for a small visual change, and somehow twenty-three dependency lines in package.json got rewritten — carets stripped, pins bumped to latest, the build dead on arrival. Here is what triggers it, how to roll back cleanly, and three guardrails to keep it from recurring.
Three Weeks of Letting Antigravity Run wrangler tail Across Six Cloudflare Workers
I run six Cloudflare Workers in parallel — four Lab sites and two storytelling blogs — and the morning log review was quietly eating an hour and a half every day. Here is what changed when I handed wrangler tail interpretation to Antigravity's Inline Agent for three weeks, what I trusted it with, and what I kept for myself.
Splitting Daily Crashlytics Triage Across Five Antigravity Sub-Agents
Running six indie iOS and Android apps, the morning Crashlytics triage was draining me. I split the workflow across five Antigravity sub-agents (Fetcher, Classifier, Repro, Patch, PR) and locked their input and output to JSON schemas. Two weeks of production data shows where the human review boundary belongs.
When Antigravity Ignores Your AGENTS.md — How to Diagnose and Fix It
You dropped an AGENTS.md at the repo root with clear rules, but the agent still pulls in banned libraries and blows past your conventions. Here is how I diagnose and fix the three most common causes I have seen across more than a hundred Antigravity sessions.
Two Weeks of Letting Antigravity's Browser Sub-Agent Handle My Weekly AdMob Mediation Review
A field record of letting Antigravity's Browser Sub-Agent handle the weekly mediation waterfall review inside the AdMob console for two weeks. What I delegated, what I kept manual, the unexpected behaviors, and what the freed-up time actually surfaced.
Integrating Antigravity Agents into My Android Release Workflow — 3 Months of Honest Findings
After 12 years of indie development and 50 million cumulative downloads, I integrated Antigravity Agents into my Android app release workflow. Here's what worked, what didn't, and where the delegation boundary actually sits.
Surviving New iPhone Resolution Support with Antigravity — 29 Changes in DefineManager.h, One Honest Recap
A real-world account of updating Beautiful HD Wallpapers and three other iOS apps for iPhone Air (420×912) and iPhone 17 Pro (402×874). What Antigravity caught, what it missed, and the two-step prompt pattern that made the 29-edit process manageable.
