When Your Antigravity Agent Opens a PR That Just Says "Update files" — and a Gate That Forces a Reviewable Summary
Pull requests opened automatically by an Antigravity agent tend to carry empty descriptions like "Update files." Here is a validation gate, with working code, that estimates risk from the diff and rejects vacuous descriptions so a human can actually review them.
When Your Antigravity-Written Tests Only Look Green: Measuring Effectiveness with Mutation Testing
Tests written by an Antigravity agent can pass and still fail to catch the bug that matters. Here is how to measure their real effectiveness with mutation testing and only adopt tests after they kill the surviving mutants — with working code.
Stop Letting Antigravity Agents Self-Report 'Done' — Completion Contracts and External Verification
An Antigravity agent reporting 'done' when the work was not actually finished is a failure mode I kept hitting. Moving the completion decision out of the agent and into code fixed it. Here is the contract, a three-layer verifier, and how it holds up under unattended, scheduled runs.
Engineering Quality Into AI Agents — When Autonomous Execution Breaks and How to Prevent It
Autonomous AI agents degrade over time. This article shows how to catch the decay before it breaks, with multi-stage verification gates and a failure dictionary that lets agents self-recover — drawn from running four sites with multiple agents in parallel.
Antigravity Agent Output Validation Errors: A Practical Fix Guide
Fix Antigravity agent output validation errors systematically: format failures, quality issues, and consistency problems across multi-agent runs — with prompt design, auto-repair patterns, self-checking, and consensus aggregation.
Antigravity × TDD Mastery: AI-Paired Development Strategy for Zero-Bug Production Code
Master TDD with Antigravity: auto-generate Vitest and Playwright tests, build smart mocks, enforce coverage thresholds, and ship with CI/CD quality gates.
