Three Decisions I Kept for Myself When Antigravity Maintained My Older Apps
How far could Antigravity maintain my long-running wallpaper and wellness apps? A field log of crash fixes and a staged rollout, with the lines I drew between delegated and retained work, and how I write context notes.
Building a Coding Agent System with Gemma 4 × Antigravity — A Complete Implementation Guide for Code Review, Test Generation, and Refactoring
A hands-on guide to building a 3-agent collaborative system using Gemma 4 and Antigravity AgentKit 2.0, covering code review, automated test generation, and refactoring suggestions. Covers code, Cloudflare Workers deployment, one month of production numbers, and five pitfalls.
When the Tech-Debt Score Drops but the Same Files Keep Breaking — Field Notes on Instrumenting Fan-in and Churn
Letting Antigravity's architecture agent score technical debt is not enough — bugs often recur in the same files after refactoring. Here is how we instrumented the fan-in times churn that static complexity misses, and reconciled the score against real incidents.
When the Agent Hands You 1,400 Replacements in One Commit, Ask for Batches Instead
Ask Antigravity to run a large codemod and you can get back one unreviewable commit. Here is a small design — ast-grep rules plus a verified batch driver — that splits a mechanical replacement into the machine's job and the human's check, with working code.
Stop Adding a Ternary Every Time a New iPhone Ships: A Table-Driven Resolution Design
Every time a new resolution arrived—iPhone Air, 17 Pro—I was bolting another screen-size ternary onto a 29-branch pile. Here is how I reshaped that into a table-driven design where adding the next device is a one-line data change, with the actual Swift from my wallpaper apps.
Two Weeks of Antigravity Walkthroughs During a Wallpaper App Refactor
Two weeks of practical notes on using Antigravity Walkthroughs during a long-running wallpaper app refactor — where it fits, where it falls short, and how I now split work between Walkthroughs and Plan Mode.
I Let Antigravity Take Over My 10-Year-Old Wallpaper App — What Happened Next Surprised Me
A real case study of handing a wallpaper app's Swift codebase — built since 2014 — to Antigravity's Background Agent. What it got right, what it missed, and what that taught me about AI-assisted refactoring.
