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.
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.
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.
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.
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.
Ask Antigravity CLI Once Whether It Actually Answers, Right Before a Scheduled Run
When Gemini CLI shuts down on June 18 and you move to Antigravity CLI, an expired token or a bad first day can let an unattended job fail silently. Here is a preflight that probes the CLI once, classifies the failure, and decides whether the real job should start at all.
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.
When a Cloud Nightly Batch Drifts From Yesterday's Result — An Input Contract and Snapshot Design for Reproducibility
When you push a batch to a cloud ephemeral worker via the Managed Agents API, the environment assumptions you took for granted locally vanish. Here is a three-layer design — environment snapshot, input contract, seed pinning — that keeps the same input producing the same result.
Regression-Testing Antigravity Agent Output in CI
Agent output drifts between identical runs and turns CI red for no real reason. Here is how I stabilized snapshot regression testing for Antigravity agents using a normalization layer and pytest golden files, drawn from running it in my own indie developer CI.
Trusting Temporal Workflows in Production — Field Notes on Idempotency, Retry Triage, and Saga Compensation
Practical notes from running Temporal as a production backend: how to make activities idempotent for real, where to draw the line between retryable and fatal errors, how to keep Saga compensation from firing twice, and how to make it all observable—built with Antigravity in the loop.
After Migrating to Antigravity CLI: Deciding How Much to Delegate to Scheduled Runs
When the June 18 Gemini CLI sunset pushes you onto Antigravity CLI, you gain background scheduled runs. Convenient, but delegate everything and you won't notice when it breaks. Here is how I separate what to schedule from what to keep manual, with the actual routing rules.
