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.
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.

Why Antigravity's AI Agent Misreads .env Values — Quoting, Whitespace, and Export Pitfalls
When Antigravity's agent writes or reads .env files, subtle differences in quoting, trailing whitespace, export prefixes, and # characters cause silent value corruption. Here are four real cases I hit in production, with concrete diagnostics and fixes.
