Combining All Four Antigravity Surfaces in One Project — Up to Running Your Own SDK Agent
How to split a single project across Antigravity 2.0, CLI, IDE, and SDK, and how to bridge between them — from diverging on design to converging on production, all the way to running a small custom agent with the Python SDK, with implementation included.
Antigravity 2.0, CLI, IDE, SDK — Weaving All Four Surfaces Through a Real Project
Antigravity ships as a desktop app, a CLI, an IDE, and a Python SDK. Beyond picking one, this guide shows how to weave all four across a single project — with a headless-execution wrapper for automation, plus the cost and migration traps to sidestep.
Running Pre-Release Checks Without Opening the IDE — Designing the Android CLI as the Verification Gate of an Unattended Pipeline
How to slot Android CLI v1.0 into an unattended pipeline as its verification gate — three layers of checks, an exit-code contract, and a density-by-locale matrix, sized for an indie developer's day-to-day.
Before a Stray Instruction in a Fetched Page Drives Your Unattended Agent — Tainting Inputs to Downgrade Capabilities
So an unattended agent that reads external pages or PDFs can't be hijacked by an instruction hidden inside them: track the taint of every input and automatically downgrade side-effecting tools. With working Python and real operational numbers.
Letting a Background Agent Work Overnight Without Regretting It by Morning — Guardrails for Unattended Runs
When you hand overnight refactoring to Antigravity's Background Agent, the morning brings as much anxiety as convenience. From three angles — blast radius, completion criteria, and detecting silent regressions — here are the guardrails that let me run unattended jobs with confidence.
Piping Antigravity CLI's JSON Lines Output Into My Own Script — Notes on Partial Lines and Exit Codes
Feeding Antigravity CLI's machine-readable JSON Lines output into my own script broke with JSONDecodeError roughly one run in three. Here are the three traps — partial lines, exit codes, and stderr bleed — and the line-buffered consumer that finally made it stable.
Keeping Scheduled Runs Reproducible: Pinning the Antigravity CLI Version to Tame Behavior Drift
The Go-based Antigravity CLI is now available to everyone, and updates are landing at a quick pace. When a CLI baked into your automation upgrades underneath you, a single morning's job can behave differently. Here is how I keep things reproducible — pinning the binary, recording its identity in each run's log, and rolling upgrades forward one job at a time — drawn from running four sites on an overnight schedule.
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.
From Gemini CLI to Antigravity CLI: Migrating Without Stopping Your Automation
Gemini CLI has been retired and the Go-rewritten Antigravity CLI is now its successor. If you have the CLI wired into CI or scheduled jobs, swapping everything at once will break your automation. Here is a concrete plan for migrating gradually, from parallel testing to full cutover.
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.
Running Antigravity CLI Unattended: Notify Only on Real Failures
A small wrapper for scheduled Antigravity CLI runs that stays silent on success and alerts you only on failures a human needs to act on, covering exit codes, transient-error triage, and duplicate suppression.
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.
