An Agent Granted 'Watch an Ad to Unlock a Wallpaper' Entirely Client-Side — Re-Verifying Reward Grants with AdMob SSV
I asked an Antigravity agent to wire up 'watch a rewarded ad to unlock a wallpaper,' and it returned an implementation that wrote the unlock flag client-side only. Here is why that is not enough, how I re-verified the reward grant with AdMob server-side verification (SSV), and how I stopped double grants too.
Before a Major Update Silently Breaks Your Overnight Automation — Designing a Staged-Adoption Canary Gate
After a major update dropped my unattended run success rate from about 98% to 63% overnight, I built a staged-adoption gate that freezes the working setup, verifies a new version against a golden output in an isolated profile, and only then adopts it. Here is the design with bash and Python.
When Xcode Cloud's Free 25 Hours Quietly Run Out at Month's End — Field Notes on Measuring and Defending Compute Time
Before Xcode Cloud's free compute allowance drains at month's end and your builds sit queued, measure where it goes. Practical field notes on pulling usage from the App Store Connect API, stopping wasteful builds early, and trimming test runs to keep CI inside budget.
A Translated Line Had Quietly Reverted to English — Guarding String Resources an Agent's Refactor Touched
Let an agent tidy your values folder and translated strings can silently revert to the source text. Here is a design and implementation that treats the default locale as the source of truth, reads every other locale as a diff, and blocks only dropped keys, reverted translations, and broken format arguments at pre-commit.
Combining All Four Antigravity Surfaces in One Project — Up to Running Your Own SDK Agent
How to split a single project across Antigravity 2.0, CLI, IDE, and SDK, and how to bridge between them — from diverging on design to converging on production, all the way to running a small custom agent with the Python SDK, with implementation included.
The Day Generation, Device, and Internal-Test Shipping Became One Step — What I Refused to Hand Over
AI Studio now turns a text prompt into a Kotlin/Compose app and carries it through the emulator, a real device, and Google Play's internal test track from one screen. Behind that convenience sits a question: how much of the moment of shipping do you hand to the machine, and what do you keep in your own hands? Here is where I draw the line as a solo developer running several apps, and the implementation that holds that boundary.
Three Paths Were Each Picking Their Own Number — Deriving versionCode From a Single Source So Releases Stop Stalling
Now that AI Studio can generate an app from one prompt and push it straight to Play's internal testing track, three paths — you, CI, and the agent — each allocate versionCode on their own and collide. Here's how to derive the number from a single source and add a pre-upload guard, with working code.
Before Your Antigravity Agents Fight Over the Same File — Ownership Manifests and Conflict Detection
Multi-agent workflows do not break at the design stage. They break at runtime. Here are the field notes: an ownership manifest that pins each agent's editable region, a git-only conflict detector, and a three-part handoff contract.
Antigravity 2.0, CLI, IDE, SDK — Weaving All Four Surfaces Through a Real Project
Antigravity ships as a desktop app, a CLI, an IDE, and a Python SDK. Beyond picking one, this guide shows how to weave all four across a single project — with a headless-execution wrapper for automation, plus the cost and migration traps to sidestep.
Running Pre-Release Checks Without Opening the IDE — Designing the Android CLI as the Verification Gate of an Unattended Pipeline
How to slot Android CLI v1.0 into an unattended pipeline as its verification gate — three layers of checks, an exit-code contract, and a density-by-locale matrix, sized for an indie developer's day-to-day.
Before a Stray Instruction in a Fetched Page Drives Your Unattended Agent — Tainting Inputs to Downgrade Capabilities
So an unattended agent that reads external pages or PDFs can't be hijacked by an instruction hidden inside them: track the taint of every input and automatically downgrade side-effecting tools. With working Python and real operational numbers.
My Daily Wallpaper Widget Stopped Updating — Measuring WidgetKit's Reload Budget and Rebuilding the Design
A widget that was supposed to rotate the wallpaper every day froze after a few days. Here is how I measured WidgetKit's timeline reload budget and extension memory limit, then rebuilt the design around a single daily timeline.
