Three Safety Nets to Test with a Fake agy Before Running the Antigravity CLI in a Container

Before you call the Antigravity CLI (agy) from Docker or a Cloud Run job, reproduce three failure modes with a fake agy: an installer that returns gzip, a hang on tool approval, and an exit code of 0 with nothing produced. Everything here rests on official docs and on code I ran myself.

Purging Cloudflare Didn't Bring Back the New Wallpapers: the Stale JPEGs Were Held by XPageSpeed on the Origin

An operations record from a wallpaper app: images overwritten at the same URL kept arriving stale even after a Cloudflare purge. Covers the three-way local/origin/edge probe that names the guilty layer, when prefix purge beats per-URL purge, and how to switch off Xserver's XPageSpeed in .htaccess without a 500.

I Asked for the Whole Quote PDF Tool at Once, Then Split It Into Four Requests

How I moved my client quote paperwork from copy-and-edit to a small PDF tool built with Antigravity, why the first single-shot request had to be thrown away, and the four smaller requests that replaced it, with working code.

When the iOS 27 Date Landed, the First File I Grepped Was AGENTS.md

iOS 27 and iPadOS 27 ship on September 14. Old version numbers linger in your source, but also in the files only your agent reads. Here is a script that counts both zones, plus the one line keyword search will never find.

Answering the age-rating questionnaire from a file in the repo, not from memory

The App Store age-rating questionnaire became mandatory in September 2026. Here is how I moved the answers into a declaration file in the repo and had a stdlib-only script argue back, with the real output.

The Five Days Between the iOS 27 RC and Release — I Check Init Order and Entitlement Restore Before Layout

A record of how I narrow the agent's search scope during the short window before an OS release — by launch path rather than by screen. Includes the audit script I run to catch consent and ads init ordering, entitlement restore gaps, and hardcoded size branches.

A dependency without musllinux wheels doesn't fail on Alpine. It just gets slower

On Alpine, a dependency without musllinux wheels can quietly fall back to pure Python. Protobuf went from 0.043ms to 36.2ms, and pip reported no error.

Why I took the show-or-not decision away from every dialog

A paywall prompt, a review request and a rewarded-ad confirmation landed on the same frame. Here is how I moved the show-or-not decision out of each dialog into a single gate, how I rewrote the agent instructions as invariants, and how a CI check keeps it that way.

A Green Build Is Not Proof That Your pbxproj Edit Was Correct

When an agent edits project.pbxproj, the build stays green while resources and script phases quietly fall out. Four structural checks and an audit script that finishes in 0.1 seconds on a 1,200-file project, drawn from running iOS apps in production.

How Silently Ignored Config Keys Slip Through CI, and Where to Block Them

A key you added to a config file can be discarded without a single warning. Measured behavior across tsc, ESLint, wrangler, npm and vitest, plus a probe that verifies a setting is actually in effect and a wrapper that turns warnings into build failures.

The Cleanup Step Removed the Working Directory, Not Its Contents — Making Unattended Destruction Fail Closed

An unattended cleanup step deleted the working directory itself instead of what was inside it. Here is why the mkdir -p that followed was not a safety net, and how a defensive-looking default value ended up selecting the destructive branch, with the actual verification output.

Turn Off the Liquid Glass Compatibility Flag Yourself, Before Xcode 27 Does It for You

UIDesignRequiresCompatibility is expected to be ignored in Xcode 27. Flip it to false yourself and you can rehearse next year's forced appearance today, on the SDK you already have. Here is what actually broke in my wallpaper apps, and the order I checked things in.
