Running Antigravity CLI Headless: Design Before It Hits CI and cron
The Antigravity CLI was rewritten in Go. Here is how to run it unattended in CI and cron, covering exit codes, idempotency, timeouts, and output parsing.
Six Days Until Gemini CLI Shuts Down — Auditing Automation Dependencies and Migrating to Antigravity CLI
With Gemini CLI ending on June 18, here is a practical walkthrough for finding gemini command dependencies hiding in cron, CI, and shell scripts, then migrating and verifying them on Antigravity CLI.
Rehearsing an Agent's Actions Before They Touch Production — Designing a Zero-Side-Effect Dry-Run Layer
Some accidents survive shadow mode and canaries: the very first time an agent touches an external API. This is the design and TypeScript implementation of a zero-side-effect dry-run layer you can bolt onto Antigravity's parallel agents, with the real numbers from running six sites autonomously.
Capping Parallel Agents With a Token Budget — Designing a Guard That Stops Runaway Cost
Running many agents in parallel quietly inflates your token bill. This is not about shrinking prompts — it is about a governance layer that meters spend in real time and cuts it off at a budget. Full design and TypeScript implementation, drawn from running six sites autonomously.
Catching "Running but Doing Nothing" Antigravity Subagents — A 3-Layer Observability Pattern Across Six Production Apps
Running Antigravity subagents across six production apps surfaced more than ten silent failures every month — exits clean, logs green, but nothing actually happened. Here is the Heartbeat / Output Trace / Decision Log pattern I now use to catch them inside 60 seconds, with code, GCP costs, and four months of running numbers.
Six Weeks of Letting an Antigravity Background Agent Watch the Drift Between AdMob and Remote Config
A six-week field report on handing weekly AdMob and Firebase Remote Config diffs to an Antigravity Background Agent, with the drift cases it actually caught and the operational boundaries I ended up drawing.
Teaching Antigravity Agents to Learn from Failure — A Solo Developer's Loop for Reusing Failure History
Antigravity agents repeat the same mistakes because each session starts blank. A solo developer's six-month run with a structured failure log, a separate observer agent, and the side-effect of overfitting.
Letting Antigravity Be Your Night-Shift Engineer: A Solo Dev Operating Model
How to operate Antigravity agents as the second engineer who works while you sleep. Task hand-off, scope boundaries, and a five-minute morning review — the model I have refined while running multiple products solo.
Designing Antigravity Agent Traces That Tell You Why It Failed — Observability in Practice
Run Antigravity agents long enough and unreadable failure logs pile up fast. This piece walks span structure, attribute design, failure tagging, dashboards, cost visibility, and retry policy — backed by six months of production metrics — so you can cut post-incident debugging time in half.
End-to-End Playbook for Antigravity Contract Work — Pricing, Contracts, and the Ongoing Operations Flow
A premium playbook for landing, delivering, and operating Antigravity-based business automation contracts as an indie developer. Covers initial discovery, pricing logic, the contract clauses that protect you, delivery patterns, and the ongoing operational issues that determine whether contract work is profitable or exhausting.
Designing Antigravity Browser Agents That Don't Go Flaky — Taming DOM Drift and Timing
A browser-agent task that passed yesterday trips today, then succeeds on retry, then fails again. Here's how I've been breaking down the causes of flaky Antigravity browser agents in production and addressing them at the design level.
