Building Production iCloud Sync Apps with SwiftUI and CloudKit in Antigravity
Build a production iCloud sync iOS app with SwiftUI and CloudKit in Antigravity. Covers CKRecord design, offline support, and the queryable-index and Development-to-Production schema pitfalls that break release builds.
Antigravity Pricing and Usage Limits — Free Tier, Pro, or AI Ultra?
A June 2026 look at Google Antigravity's pricing: what the free tier covers, when Pro ($20) is enough, when AI Ultra ($100) pays off for parallel agents, and a simple way to measure your own quota usage before deciding.
VS Code × Antigravity Migration Guide — Seamlessly Transition Your Dev Environment to an AI IDE
A complete guide to migrating from VS Code to Google Antigravity. Learn how to transfer settings, extensions, keybindings, and effectively use both editors together.
The One File That Stops Startup: Guarding config.json Integrity Before Scheduled Runs
Antigravity 2.3.1 fixed a bug where an empty or corrupt config.json blocked startup. The symptom was fixed; the causes of corruption still live in your environment. Here is a three-layer guard — validate, snapshot, restore — that runs before a scheduled job, with working code and notes from running it nightly.
When the JSDoc an AI Wrote Quietly Stopped Matching the Code: Field Notes on Measuring Documentation Drift
AI-generated JSDoc gets written once, looks authoritative, and is then trusted and left to rot. Field notes on hashing function signatures to detect staleness, tracking a drift rate, and fixing only the blocks that actually diverged.
After Compose-First: Choosing Which View Screens to Migrate, Ranked by Churn Instead of Count
Google has declared Android development Compose-first. Here is how I rank View-based screens for migration using git history rather than screen counts, with the scoring script I actually ran and the three places partial migration quietly duplicates state.
Three Quarters of My Reference Notes Never Reached the Agent: Measuring What head Cuts Away
I fed reference notes to a scheduled agent with cat and head, and the lines that mattered were quietly cut. Here is the measurement, and how I replaced a line count with a section-level contract.
The More I Wrote in AGENTS.md, the Less Got Followed — Measuring Adherence and Cutting Rules
The rules in my AGENTS.md were being ignored — not from precedence conflicts or load failures, just plain ignored. Here is how I turned rules into checkable predicates, measured adherence over three weeks, and cut the file in half.
Three Ways to Hand 4,000 Lines of Logs to an Agent — Paste, .txt Attachment, or @ Reference
v2.3.0 added plain-text attachments, which means there are now three ways to hand a long log to an agent — and a new question about which one to pick. Here is how I trim, measure, and decide, with the scripts I actually run.
When to Hand Your Agent the Next Instruction: Waiting, Interrupting, and Queuing, Measured
Antigravity v2.3.0 added message queuing and Send Now. I measured waiting, interrupting, and queuing against the same yardstick, found that 41% of queued instructions arrive stale, and cut rework from 22% to 9% with a twenty-line stamp.
When Your Agent Commits a .bak File: Why Fix-Tool Artifacts End Up in Git
Backup files like .bak and .orig slip into commits after an agent runs a --fix tool. Here are the reproduction conditions, the real root cause, and three fixes: narrowing the staged scope, wrapping the fixer, and adding a pre-commit extension gate.
Quarantining the Dependencies Your Agent Adds, Before They Install
When an agent adds a dependency overnight, nobody reviews the lifecycle scripts that run at install time. Here is how I turned the default off and built a quarantine score to let the safe ones through.
