Canary Deployment with Auto-Rollback for AI Agents — Protecting Production with Antigravity and Burn-Rate SLOs
A practical playbook for shipping new AI agent versions through canary deployment on Antigravity, with automatic rollback driven by burn-rate SLOs. Includes a lightweight setup that solo developers can sustain.
Defining 'Done' with Antigravity Agents: Writing Acceptance Criteria into Your Prompts
When Antigravity returns code that is only halfway working, the usual cause is a missing Definition of Done. Here is the three-layer fix.
Giving Your Antigravity AI Agents a 'Time Budget' — A Production Scheduling Design That Unifies Timeouts, Priorities, and Deadlines
Your AI agent's response time creeps up, users drop off, and unexpected costs pile on. This guide walks through giving Antigravity agents a single 'Time Budget' object that unifies timeouts, priority, and deadlines, drawing on Masaki Hirokawa's production experience.
Why Antigravity Agents Can't Read Your .env File — Three Propagation Paths to Check First
When an Antigravity agent fails with Missing API_KEY but the same build works in your terminal, the cause is one of three env propagation paths. Diagnose each.
Designing Confidence Scores for Antigravity Agent Outputs: Auto-Approve the Certain, Escalate the Ambiguous
Reviewing every Antigravity Agent output by hand does not scale. Attach a confidence score to each output, auto-approve the certain ones, and only escalate the ambiguous to humans. This guide walks through implementation and threshold calibration end to end.
The Self-Critique Architecture for AI Agents — Four Reflection Patterns That Make Antigravity Outputs Trustworthy
Four production-tested patterns for adding self-critique loops to Antigravity agents, with implementation code, stopping conditions, confidence calibration, and cost-control strategies.
Replay-Driven Agent Design — Time-Travel Debugging for Production AI Agents
Reproduce one-off agent failures from production on your laptop. A practical three-layer replay design — event, state, and decision — built on top of Antigravity's Manager Surface, with TypeScript code you can drop into your own stack.
Building a Subscription AI Agent Service with AgentKit 2.0 — Stripe Billing to Monthly Revenue Design
Complete guide to building and monetizing a subscription-based AI agent service using AgentKit 2.0. Covers Stripe integration, multi-agent design, pricing strategy, and churn prevention — everything needed to reach stable monthly recurring revenue.
Debugging Antigravity AI Agents: A Systematic Diagnosis Guide
A systematic approach to diagnosing AI agent failures in Antigravity—covering startup failures, tool call errors, loop detection, and incorrect behavior—with practical debugging patterns for each.
