When a Timed-Out Unattended Agent Leaves a Half-Written File Behind
When a scheduled agent gets killed on timeout, it can leave a half-written file that silently poisons the next stage. Here is the atomic write, stale-temp cleanup, and post-write content assertion I use to keep unattended pipelines from breaking.
Don't Lose Failed Agent Jobs: Designing a Dead-Letter and Requeue Path
Scheduled agents fail silently overnight and the work simply vanishes. Here is how to catch those failures with a dead-letter store and a staged requeue, drawn from running four sites on autopilot as an indie developer.
More Agents Won't Speed Up Every Part of Your Pipeline — Designing the Parallel/Serial Line
Antigravity 2.0's parallel multi-agent execution is powerful, but adding agents doesn't make everything faster. Here's how I decide which work to parallelize and which to keep serial, derived from invariants and a dependency graph, with examples from running several sites as a solo developer.
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.
Parallel or Keep It Serial: The Break-Even Point When Orchestrating Multiple Agents
Should you run agents in parallel or keep them serial? A simple way to estimate the break-even between coordination cost and saved wall-clock time, plus how I actually split parallel vs serial across four scheduled sites.
Handing Visual Regression to a Parallel Agent in Antigravity 2.0
A design for running a dedicated headless visual-regression agent alongside your main implementation agent using Antigravity 2.0's parallel orchestration — with a working harness and the reproducibility traps I hit in production.
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.
Three Boundaries I Draw Before Handing Work to an Antigravity 2.0 Agent
What to hand a background agent, and what to keep in your own hands. The three boundaries I actually drew while running solo-dev automation in parallel, and how to encode them so the lines hold.
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.
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.
Making My Managed Agents Batch Survive a Crash Without Redoing Everything
Running a 200-item batch on the Managed Agents API kept torching tokens, because every mid-run failure restarted from item one. Here is the checkpoint-and-idempotency design I added so the batch resumes from where it died.
Before You Trust 'It's Fixed' — Make the Agent Confirm Your Live URL Actually Renders
The agent reported it had fixed the bug and deployed successfully, yet the production page was blank. To prevent the empty-body-with-200 trap, here is how to add a completion gate that makes Antigravity 2.0's Browser Sub-Agent open the live URL and confirm the main content selector is actually filled.
