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.
Putting a Verification Step After 'Done': Confirming What Your Antigravity Background Agents Actually Produced
An Antigravity 2.0 background agent reported 'Done,' yet the output was nowhere to be found. Running several sites on autopilot as a solo developer, I hit this gap more than once. Here is how I learned to check ground truth instead of the agent's self-report.
When Your Agent Got 4x Faster: Rebuilding the Parallel Pipeline
When the Antigravity CLI moves to a faster model, the bottleneck in your parallel agent pipeline shifts. Here is a practical way to rethink verification, task granularity, concurrency, and cost caps with speed as the new baseline.
Does the New CLI Do the Same Job? An Output-Parity Gate Before Switching to Antigravity CLI
With Gemini CLI shutting down on June 18, here is how I froze the old CLI's artifacts as a golden baseline and built a parity harness to catch regressions before cutting over to Antigravity CLI — with normalization and a go/no-go gate, in code.

As Google consolidates its AI coding tools into Antigravity and the personal Gemini CLI sunsets on June 18, here is a practical design for quantifying vendor lock-in and keeping a configuration you can step away from at any time.
After Gemini 3.5 Flash Became the Default, Route Flash and Pro Per Task
Now that Antigravity's default Flash is Gemini 3.5 Flash, leaving everything on Flash wastes accuracy and forcing everything onto Pro wastes time. Here is a two-axis decision table for splitting work between Flash and Pro, plus the routing setup to wire it into your agents.
A Compatibility Shim That Bridges Old Scripts to agy Before Gemini CLI Shuts Down
Ahead of the June 18 Gemini CLI shutdown, instead of rewriting every gemini call scattered across cron and CI at once, a thin compatibility shim can bridge them to the Antigravity CLI (agy). Here is the approach with working shell scripts.
Budgeting Quota So Parallel Agents in Antigravity 2.0 Don't Run Dry
Run several agents at once in Antigravity 2.0 and your quota can be gone by mid-afternoon, right when you need it for the real work. Here is how I measure per-agent consumption, find the Pro-vs-Ultra break-even, and budget so I never hit the ceiling.
Running Antigravity Behind a Proxy
Keep Antigravity working behind corporate proxies, SSL inspection, and hotel Wi-Fi: layer-by-layer diagnosis, certificate trust, NO_PROXY design, and connection profiles with a local LLM fallback.

How to keep Antigravity agents behaving consistently across several independent repositories when a monorepo isn't an option. A layered governance design with a working distribution script and drift audit, drawn from running four sites in parallel.
Why Your Antigravity Agent Stops Mid-Task with 429 RESOURCE_EXHAUSTED, and How to Fix It
When you hand a long task to an Antigravity agent, it sometimes halts halfway with a red 429 RESOURCE_EXHAUSTED. That is a rate-limit or quota signal, not a bug. Here is how I diagnose the three flavors of 429 in production, and how to keep your agent from stalling on the same wall twice.
A Month with Antigravity Inspector — Reading the Agent's Real Behavior
Notes from a month of seriously using Antigravity's Inspector while maintaining four wallpaper apps. The reading order I settled on, the panels I actually look at, and the pitfalls that quietly mislead you.
Fixing Antigravity Google Sign-in That Won't Return From the Browser
When you press Sign in with Google in Antigravity and the browser just hangs without returning to the editor, the cause is rarely a single thing. Here is how I narrow it down across four layers — callback port, third-party cookies, stale session files, and network path — using only commands I keep close on every machine.
Why Antigravity Agents Hang on ssh, sudo, and git rebase -i — Diagnosing and Permanently Fixing the Missing TTY Problem
When you ask an Antigravity agent to deploy, the terminal panel stops on 'password:' and never moves. The agent isn't broken — the shell behind it has no PTY, so interactive prompts have no one to answer them. Here's how to diagnose and remove every interactive command from your agent workflow.
When Japanese Prompts Drag Down Antigravity Quality — A Multilingual Operator's Hybrid Workaround
Switching Antigravity's UI to Japanese is one thing; getting Antigravity to produce quality output from Japanese prompts is another. As an indie developer running multilingual apps and Japanese-language blogs in parallel, I break down measured quality drops with Japanese prompts, a hybrid English-Japanese strategy, a lightweight translation layer, and the reality of running Gemma 4 locally for Japanese.
Which Local-LLM Path to Keep with Antigravity: Ollama, LM Studio, or Raw Gemma 4 (Indie Judgment Notes)

Antigravity vs Codex CLI After Six Months in Production — Measured Comparison from Running Six Sites in Parallel
I ran Antigravity and OpenAI's Codex CLI in parallel for six months across six auto-publishing pipelines at Dolice. This is the measured comparison — not benchmark numbers, but the real decision axes that mattered: concurrency, fix cost, recovery behavior, and monthly bill — with the production data behind each.
Why Antigravity Agents Hit `Permission denied` on git push, and How to Fix It for Good
Your Antigravity agent finishes the edits, tests pass, the commit message is sharp — and then git push fails with `remote: Permission to ... denied` or `fatal: Authentication failed`.
