Migrating to Antigravity 2.0 Without Stopping Your Automation: Parallel-Run and Rollback Design
How to move to Antigravity 2.0 without breaking running automation: how to set up a parallel-run window, verify output parity, pin versions, and keep a one-command rollback path, based on migrating four sites one at a time.
I Started the Ad SDK Before Asking for ATT — the Init-Order Bug That Quietly Lowered First-Session eCPM
When I rolled AdMob mediation out to four iOS apps, only the very first session showed weaker ad revenue. The cause was the order between the ATT prompt and MobileAds initialization. Here is why the order matters, plus how I had Antigravity audit the init sequence across all four apps.
Handing Visual Regression to a Parallel Agent in Antigravity 2.0
A design for running a dedicated headless visual-regression agent alongside your main implementation agent using Antigravity 2.0's parallel orchestration — with a working harness and the reproducibility traps I hit in production.
Choosing Among Desktop, CLI, SDK, and Managed Agents for the Same Job
Antigravity 2.0 has several surfaces: desktop, CLI, SDK, and the Managed Agents API. Which one should run a given task? Here is a framework for choosing the surface from the nature of the work.
On Cutover Day to the Antigravity CLI, Verify Production Automation by Side-Effect Equivalence, Not Output
On the day you switch from the Gemini CLI to the Antigravity CLI, verify production automation by the equivalence of side effects — files written, commits, network calls — instead of matching stdout. A sandbox parallel run and a go/no-go cutover gate, with implementation steps.
When Your Antigravity Agent's Usage Ledger Quietly Drifts From Stripe's Bill — Field Notes on Idempotency, Late Events, and Reconciliation
Usage-based billing for Antigravity agents fails silently when your internal usage ledger and Stripe's Meter Events aggregation drift apart. Field notes on idempotency keys, absorbing late events, the 35-day window, and a daily reconciliation job.
Using the v2.1.4 Quota Screen for a Weekly Reckoning: Reading Used and Remaining to Run an Indie Budget
How to turn the used/remaining display in the reworked Antigravity v2.1.4 quota screen into a weekly reckoning instead of a gut feeling. Baseline recording, burn-rate math, and allocation across multiple projects, written as an indie-dev operating routine.
Gating Your Agent's Commits With pre-commit — Keeping Broken Changes Out of the Main Repo
How to wire up a pre-commit gate that lints, type-checks, runs fast tests, and scans for secrets the moment Antigravity's agent commits — with measured timings and the ordering that keeps it fast.
Three Boundaries I Draw Before Handing Work to an Antigravity 2.0 Agent
What to hand a background agent, and what to keep in your own hands. The three boundaries I actually drew while running solo-dev automation in parallel, and how to encode them so the lines hold.
Spending Less on Failure Without Swallowing It: A Retry Budget for Agents Built Around Gemini 3.5 Flash
A design that separates an agent's retries from quietly swallowing errors: classify the failure first, then retry within a budget. Grounded in the speed and price of Gemini 3.5 Flash, with per-task caps, logging, and a weekly tightening routine.
Stopping Parallel Agents from Clobbering the Same File
When you run several agents at once in Antigravity 2.0, two of them can write to the same file and one set of changes silently disappears. Here is how to design write arbitration inside a shared workspace.
After Generating Several Candidates, Which One Do You Adopt? Designing Best-of-N That Arbitrates by Verification
With Gemini 3.5 Flash's speed, generating several implementations of the same task has become practical. The hard part is no longer generation but arbitration. Here is the design and TypeScript implementation of a Best-of-N arbiter that picks the winner using verifiable signals only — not majority vote, not self-reported confidence.
