Keep the Self-Debugging Agent Away From Live Ads: Three Layers Against AdMob Invalid Traffic
When Antigravity 2.0's real-browser self-debug renders a live AdMob unit, every pass counts as an impression, and Google may read it as invalid traffic. Here is a three-layer setup, with measurements, that keeps the agent from ever touching a production ad.
When Your Agent's Commits Pick Up Junk Files: Fixing It With Staging Scope and a Message Convention
Agents tend to run git add -A, sweeping .bak files and caches into your history, and leave a one-word message. Here is how a staging allowlist, a preflight, and a fill-in message template stop it.
Protecting Your Agent Stack's Known-Good State with a Single Lockfile — Change-Budget Design for an Era of Simultaneously Moving Parts
When the IDE build, CLI, model, and dependencies all move at once, you can no longer tell which one caused a regression. Here is a change-budget design that pins your known-good state to one lockfile, with working code and operational logs.
Make the Self-Debugging Agent Walk the Logged-In and Post-Paywall Screens
By default, Antigravity 2.0's real-browser self-debug only sees the logged-out free view and reports success. To catch billing regressions, inject an authenticated session and paid state into the agent's browser and force coverage with assertions.
Paid, but the Ads Won't Go Away — Closing a StoreKit 2 Transaction.updates Launch Race with Antigravity
How I traced a StoreKit 2 launch race that dropped transactions arriving right after startup, pinned the listener to the app's lifetime instead of a view's, reconciled with currentEntitlements, and let Antigravity turn it into a StoreKitTest regression suite.
Point Real-Browser Self-Debug at a Throwaway Preview, Not Localhost or Production
Antigravity 2.0's real-browser self-debug is genuinely useful, but aim it at the wrong place and it touches production data. Here is a practical way to confine it to a per-branch throwaway preview and neutralize email, billing, and webhook side effects.
When AppEnum Breaks in App Intents — Designing EntityQuery so Siri Can Pick From a Catalog That Grows Every Day
Writing an App Intents parameter with AppEnum works fine while the options are fixed, but it cannot survive content that grows daily. Here is the AppEntity + EntityQuery design that lets Siri and Shortcuts correctly pick from a dynamic catalog, including identifier stability and Spotlight pitfalls.
When Universal Links Break Silently — Catching Association Drift with an Agent-Run Verification Gate
Universal Links and App Links fall back to the browser with no error when your association files or entitlements drift apart. Here is a design that generates the files from one source of truth and hands weekly and pre-release checks to an agent.
Before You Let Siri Run an Agent-Written App Intent — Classify by Side Effect and Gate the Destructive Ones
Letting Siri or an assistant run an Antigravity-generated App Intent without a gate means a destructive action can fire from a single voice command. Here is how I classify intents by side effect, gate the irreversible ones, and catch missing gates before push.
When CI Passes but App Review Rejects Your Screenshots — Field Notes on Measuring the Freshness of Your Validation Rules
Store asset validation can pass in CI and still get rejected in review, because the rules themselves go stale. Move store specs into a freshness-dated contract file, then add locale overflow checks and perceptual diffs.
The Failure That Never Shows Up in Your Crash List — Collecting ANR Traces with ApplicationExitInfo and Handing Triage to an Agent
ANRs never reach your crash handler. Here is how I collect them at startup with ApplicationExitInfo and hand triage to an Antigravity agent, with five weeks of real numbers.
Catching Download Size Regressions Before Submission Day — A Weekly Agent Gate for AAB/IPA Size Budgets
Mediation SDKs and bundled assets quietly inflate download size. A design for size ledgers, budget gates, and agent-driven delta attribution using bundletool and App Thinning reports.
