What Qwen3.7-Max's '35-Hour Autonomous Run' Means in Practice — Design Notes from an Indie Dev Running Both Antigravity and Claude Code
Alibaba's Qwen team published a demo where Qwen3.7-Max ran autonomously for about 35 hours and made over 1,158 tool calls. I walk through what that number means for a one-person shop using both Antigravity and Claude Code, and how to translate the design lessons into a personal evaluation set.
Forensic Audit Trail for Antigravity Background Agent — Cloudflare R2 logging that reconstructs decisions six months later
How to design a decision-log audit trail for long-running Antigravity Background Agents so you can still reconstruct why an agent did what it did six months later — schema, R2 write layer, PII masking, and Polars queries.
Orchestrating Six iOS App Updates in Parallel with Antigravity's Main and Sub Agents
Running six iOS app updates in parallel — new resolutions, Firebase SPM migration, StoreKit 2, and ATT ordering — with Antigravity's Main + 6 Sub agents. The notes on what to parallelize and what to keep serial.
Running 50+ AdMob Mediation Groups Alone: Four Tasks I Handed to an Agent, Four Decisions I Kept
Two wallpaper apps on iOS and Android put me past 50 AdMob mediation groups. Here are the four tasks I handed to an agent, the four decisions I kept, and the sample-size hole I later found in the evaluation code I had published.
Record & Replay for Antigravity Agents
How to deterministically replay a failed Antigravity Agent run offline, drawn from a month of running it across four production sites. Covers boundary recording, R2 + KV storage costs, PII masking, and a working TypeScript harness.
Splitting Pre-release QA Across Four Antigravity Subagents — A Design Note from a Solo Mobile Developer
A design note from a solo indie developer running six iOS / Android apps in parallel, sharing how Antigravity subagents are split into four parallel paths for pre-release QA. Covers the boundary decisions, prompt templates, termination rules, and merge logic with concrete examples.
Why Antigravity's Browser Sub-Agent Reads SPAs as Empty Pages — and Three Wait Strategies That Stuck for Me
When you hand an SPA dashboard to Antigravity's Browser Sub-Agent, get_page_text often returns before the real content is rendered, and the agent reports an empty page. Here is how I diagnose the symptom and the three wait strategies that have stabilized my routine.
Antigravity Multi-Agent State Tiers — A Three-Layer Design with Ephemeral, Journal, and Canonical
Before your Antigravity Background Agents and Sub-agents start mixing up their memory, split agent state into three lifetimes — ephemeral, journal, canonical — and map each to the right Cloudflare store. Includes a TypeScript approval gate for write-back, and what changed when headless runs stopped silently auto-approving.
Implementation Notes: Running AdMob Mediation A/B Tests with Antigravity Parallel Agents
Notes from automating AdMob mediation A/B testing using Antigravity parallel agents across an indie wallpaper-app portfolio with 50M cumulative downloads. Covers joint eCPM + ARPU optimization, the 7-day rotation pipeline, and the rollout design that does not break production.
Cost Attribution for Antigravity Agents — A Showback Architecture That Maps Execution Cost Back to Tenants Across Multi-Product Operations
A multi-tenant Showback architecture for Antigravity agents running across multiple products, with the schema, propagation patterns, and seven months of production numbers from running 4 sites and 6 apps in parallel.
Designing Antigravity Agents That Survive Multi-Hour Batches — A 4-Layer Durability Pattern From the Trenches
Long-running Antigravity batch agents will fail somewhere. After running them against the operations of an indie app business, I distilled four durability layers — checkpoint granularity, persistence choice, idempotent restore, and context summarization — into a single, opinionated design memo with working code and real cost numbers.
Handing Nightly Wallpaper Asset Updates to a Background Agent — Time Budgets, Duplicate Detection, and a Completion Gate
A reproducible account of handing nightly wallpaper asset updates to Antigravity's Background Agent. Covers how to write the task definition, perceptual-hash duplicate detection, one-pass resizing across 12 device profiles, a morning report you can review in five minutes, and the time-budget and completion-gate design that makes unattended runs safe.
