Before an Agent's .proto Edit Silently Breaks Binary Compatibility: Gating Wire Compat with buf breaking
When an agent edits your .proto files, the text can look perfect while wire compatibility quietly breaks. Here is how to stop field-number reuse and unsafe type changes with a working gate built from buf breaking and reserved.
Antigravity DevContainer: A Complete Setup Guide for Reproducible AI Development
An end-to-end guide to running Antigravity inside a DevContainer — Docker setup, Ollama integration, secrets, volume persistence, team distribution, and CI parity.
When Antigravity Reads Cloud-Synced Files as Empty: The Online-Only Placeholder Trap
A file is right there in Finder, yet the Antigravity agent insists it is empty or missing. The culprit is an online-only placeholder created by cloud sync. Here is how to spot it, hydrate the data, and design a workspace that avoids the problem.
Measuring the Rework Rate of What You Delegate to Agents: Drawing Delegation Boundaries with Numbers, Not Instinct
How much should you hand to an agent? I drew that line by instinct for a long time. Here is a practical way to compute a per-category rework rate from your git history and redraw the delegation boundary with numbers, with working code.
When Lighthouse Is Green but Search Console's Core Web Vitals Are Red — Field Notes on Naming the Slow Interaction with Real-User Data
Lighthouse scores in the 90s, yet field Core Web Vitals won't budge. Here is how I closed the lab-vs-field gap with real-user monitoring (RUM), named the exact interaction driving a slow INP, and fixed it with Antigravity.
Antigravity Now Saves OAuth Tokens to the OS Keyring — Keeping Auth Alive in Headless Runs
In v2.2.1, refreshed OAuth tokens are saved to the OS keyring automatically. Pleasant on the desktop, but on headless scheduled runs the vault itself may not exist and auth quietly breaks. We design explicit backend selection, a safe file fallback, and per-location liveness checks.
When Successful Automation Quietly Stops Earning Its Keep: Designing for Value Decay and Retirement
A dashboard full of green success logs often hides the most dangerous kind of failure. Here is a design — with working code — for surfacing automations that keep succeeding while producing no value, and deciding whether to retire, repair, or keep them.
The Thumbnails Had Been Drifting: Catching Image-Asset Regressions with pHash and SSIM in Your Agent Workflow
After letting an agent rewrite an image pipeline, visual quality can quietly slip in ways tests never catch. This guide shows how to measure that drift with two numbers — pHash and SSIM — and block it in CI, from threshold calibration to a ready-to-run gate script and Antigravity integration.
When Antivirus Blocks Antigravity's Launch, Verify the Signature Before You Allow It
When the Antigravity desktop app won't launch because antivirus stepped in, here's how to tell a false positive from a real threat. Verify the code signature on macOS Gatekeeper and Windows Defender first, then allow-list with the narrowest possible scope.
Before Your Finger Learns the Approval Dialog: Folding Antigravity Permissions Into One Policy
Scattered approval dialogs, per-MCP allowlists, repeated re-auth. Built around Antigravity 2.2.1's unified permissions and OAuth keyring storage, here is how I fold every permission into a single policy and design away approval fatigue, with working code and measured numbers.
When Parallel Agents Ran the Same Task Twice and Quietly Doubled the Bill — Field Notes on Measuring and Stopping Duplicates
The bill for our parallel agents came in about 1.9x higher than expected — because multiple workers were running the same task twice. These are field notes on measuring the duplication, stopping it with idempotency keys, and attributing cost per task.
Semantic Search Over Your Own Codebase with Gemini Embeddings and sqlite-vec: An Incremental Index Keyed on Git Blob Hashes
A build log for semantic search scoped to your own repository, using Gemini embeddings and sqlite-vec. Covers an incremental pipeline that skips re-embedding unchanged files via git blob hashes, with measured index size and query latency.
