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.
When Your Antigravity Agent Eval Gate Keeps Flickering — Build Notes on Pass/Fail That Survives Non-Determinism
Same code, yet the eval passes in the morning and fails by noon. The first thing that breaks when you put agent evaluation into CI on Antigravity is the stability of the verdict. Here's how I separate noise from real regression and lock down pass/fail in code.
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.
Generating Multilingual Release Notes with the Managed Antigravity Agent via the Gemini API
A hands-on record of building a pipeline that turns git commit logs into multilingual App Store and Google Play release notes using the Managed Antigravity Agent, now in public preview through the Gemini API.
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.
Bundling Nightly Tasks With agy Async Jobs — A fan-out, poll, join Design
The Go-based Antigravity CLI (agy) can detach jobs and run them asynchronously. Here is a fan-out, poll, join design for firing many long-running tasks at once, collecting their job IDs, and waiting for completion — drawn from an actual nightly batch.
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.
Feeding Spec PDFs to Antigravity 2.1.4: A Practical Attachment Workflow
Field notes on using the PDF attachment added in Antigravity 2.1.4 as a spec-driven implementation workflow: supported formats, the scanned-PDF trap, token cost, and how to verify the output.
Treating the Managed Agent as a Cost-Capped Throwaway Worker: Isolating Untrusted Input from Production
How to use the Managed Antigravity Agent, now in Gemini API public preview, as a throwaway worker that is born and discarded per request. Cost caps, isolation, and idempotency with implementation steps.
Supervising Multiple Agents at Once on the Antigravity 2.0 Desktop: Screen Layout and Interruption Design
Now that Antigravity 2.0 has been recast as an agent control tower, here is how I lay out the screen, decide when to interrupt, and surface state when running several agents in parallel.
