Stop Dialogs From Stacking: One Gate for Paywalls, Review Prompts, and Rewarded Ads
A field record of curing the bug where a paywall, a review prompt, and a rewarded ad all surface at once, fixed with a single priority-based modal gate. I let an Antigravity agent sweep up the scattered show() calls, but kept the display policy in my own hands.
Accounting for Which Agent Spent What: A Cost Attribution Design by Task
Your month-end bill is one number, but running multiple agents on Gemini 3.5 Flash hides which task ate the cost. Separate from a budget guard, I share a cost-attribution accounting design that maps usage to per-task and per-site cost, with a solo-operator implementation and numbers.
Your Antigravity LLM App Drifts on Cost and Quality While the Dashboard Stays Green — Instrumentation Field Notes
Watching only total cost and latency hides the slow drifts that hurt. These are field notes on attributing telemetry by feature, tenant, and prompt version so you catch quality regressions and cost spikes early.
Tracing Parallel Agents After the Fact: Observability with Structured Logs and Spans
Running multiple agents in parallel on the Antigravity 2.0 desktop makes it impossible to tell which one is doing what. I share an observability design that drops tangled print debugging for run_ids and spans you can trace afterward, with a solo-operator implementation and numbers.
When the Antigravity CLI Stalls on a 401 During Unattended Runs
If your scheduled Antigravity CLI job suddenly stops producing output after a single 401 in the logs, here is how to separate an expired token from a silent re-login prompt and rebuild your unattended setup.
Antigravity vs Gemini Code Assist (2026): Which Google AI Coding Tool to Use?
Antigravity and Gemini Code Assist are both Google AI tools for developers, but they serve very different purposes. This guide breaks down the differences by features, cost, and use cases to help you choose — or use both together.
Three Prompts I Tried When Antigravity's Code Felt Correct But Not Mine
When Antigravity's output runs but never quite fits your codebase, the gap is usually missing design context. Three prompting patterns for handing over intent — plus the cases where even that wasn't enough, from real indie development.
Antigravity vs OpenAI Codex: Which AI Coding Agent to Choose in 2026
Antigravity or OpenAI Codex? A hands-on 2026 comparison of architecture, features, pricing, and the clear cases where each wins — plus when it pays to use both.
Making Managed Agent Batches Safe to Re-run: Idempotency and Checkpoints
Running overnight batches on the Antigravity 2.0 Managed Agents API makes recovery from partial failure unavoidable. Starting from a duplicate-post incident, I share the implementation of idempotency keys, a checkpoint store, and resume logic, with real numbers from solo operations.
Feeding axe-core Findings to an Antigravity Agent: An Accessibility Fix Loop in CI
Detect accessibility violations with axe-core, hand them to an Antigravity agent as fixable tasks, and wire detection, triage, fixing, and re-verification into a single CI loop. Includes a diff gate that blocks only new violations and a scoping design that keeps the agent from breaking screen readers.
Collecting Guardrails Across Projects Into One Place — A Thin Wrapper Around the Antigravity SDK
When you copy the same safeguards into every project, you eventually fix one and leave the other stale. Here is a design that builds a single thin wrapper around the Antigravity SDK to centralize cost caps, allowed tools, and output validation — from someone running several apps in parallel.
Measuring the Go-Based Antigravity CLI's Responsiveness to Rethink My Nightly Batch
The Antigravity CLI was reimplemented in Go, and startup and first-response feel different now. I measure startup, time-to-first-token, and throughput as three separate intervals, then use those numbers to move my nightly batch from serial to parallel.
