Giving Antigravity Agents Safe Write Access — Production Permission Boundary Design
A practical guide to designing Permission Boundaries that let AI agents safely touch production databases, deploys, and billing APIs — with dry-runs, approval queues, and audit logs.
Antigravity × Gemma 4: Building an On-Prem PII Masking Agent — Production Design That Keeps Sensitive Data In-House
When customer data cannot leave your network, here is the on-prem PII masking pipeline I run in production using Antigravity and Gemma 4 — including the audit, key, and latency decisions that hold up under SOC2 review.
Why Antigravity's Browser Preview Goes Blank — A Diagnosis Workflow That Actually Works
Your agent says the dev server is up, but Antigravity's embedded preview is blank. Here's the order of checks I run to narrow it down to the real cause in a few minutes.
Building a Subscription SaaS on Antigravity Multi-Agent — Role Splits, Quotas, and Stripe Integration That Actually Stick
Antigravity multi-agent is fun to demo. Turning it into the core of a paying subscription SaaS is a different game. Here's the implementation playbook — agent role splits, idempotent task queues, Stripe metered billing, and retention — with working TypeScript code.
Implementing Agent-to-Agent Communication in Antigravity Using the A2A Protocol
A practical guide to wiring agents together with the A2A protocol on Google Antigravity. Covers the design rationale, endpoint shapes, authentication, error handling, and the production-readiness checklist I run through.
Antigravity Background Agent Stops Mid-Task — 5 Causes and Fixes
Learn why Antigravity's Background Agent stops before completing tasks and how to fix it. Covers timeout, context exhaustion, network drops, file conflicts, and error loops — with concrete prevention strategies.
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.
Shipping an Antigravity Agent as a Paid API — Gateway Design, Usage Billing, and Enterprise Pricing from Scratch
A complete implementation guide for turning Antigravity agents into a billable API service. Covers API gateway, API key management, token tracking, Stripe Metered Billing, rate limiting, and enterprise SLA design — with production-ready code throughout.
Force Gemma 4 to Stay Inside Your Schema: A Production Guide to Constrained Decoding in Antigravity with GBNF, Outlines, and vLLM
A production-grade guide to running Gemma 4 locally in Antigravity while guaranteeing schema-compliant output. Covers llama.cpp GBNF grammars, Outlines with Pydantic, and vLLM guided_json — with concrete Python code and failure-mode fallbacks.
Implementing Antigravity's A2A Protocol — Practical Patterns for Agent-to-Agent Conversation
A hands-on guide to Antigravity's A2A (Agent-to-Agent) protocol. Walks through the minimal two-agent setup and three real-world patterns — fire-and-forget, bidirectional confirmation, and scatter-gather — with runnable samples.
SRE for Antigravity Agents — Taming Probabilistic Systems with SLOs and Error Budgets
AI agents are probabilistic by nature, so running them in production without SRE thinking is risky. This guide applies SLIs, SLOs, and error budgets to Antigravity agents with working code, and shows why the textbook 14.4x burn-rate alert never fires on a loose SLO.
