When CLI, Desktop, and SDK Share One Agent Harness: Designing for Consistent Behavior
Now that Antigravity's CLI, desktop, and SDK share one agent harness, here is how to separate what stays consistent from what differs by environment, and how to align behavior with smoke tests and a version-tracking habit.
Your Antigravity Sandbox Isolates Multi-Agents Less Than You Think — Notes on Containing the Blast Radius
An Antigravity sandbox gives you the feeling of isolation, but isolation leaks through three real gaps: shared volumes, over-broad allowed domains, and approval fatigue. Field notes on plugging the leaks, containing the blast radius by design, and proving isolation holds with tests.
How to Orchestrate Multiple Agents: Drawing the Line Between Parallel and Serial Work
Antigravity 2.0 brings true parallel execution across multiple agents. But making everything parallel does not make it faster. Which work should fan out in parallel, and which should stay serial? This is an orchestration design that does not fall apart, viewed through dependencies and contention.
Parallel or Keep It Serial: The Break-Even Point When Orchestrating Multiple Agents
Should you run agents in parallel or keep them serial? A simple way to estimate the break-even between coordination cost and saved wall-clock time, plus how I actually split parallel vs serial across four scheduled sites.
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.
