Before Handing an Agent a .zip: Dropping .git Cut 29 MB to 15 MB, and 28 Secret Warnings Turned Out to Be Noise
Antigravity app v2.23.0 lets you attach a .zip. I packed my own repository to count what .git weighs and how many secret-scan warnings are false alarms, and I leave the full Python script that excludes, scans, and writes a manifest.
Turning Gut-Feeling Judgments into Rules an Agent Can Actually Follow
A small, repeatable way to turn the judgment calls that live only in your head into written rules an Antigravity agent can apply, with a quick check against past cases.
The Image Model Shuts Down on October 29 — Find Every Call in Your Agent Setup and Cut Over with a Way Back
The Gemini API deprecations table lists a shutdown date of October 29 for the image model gemini-3.1-flash-image. Here is how I locate every call scattered across configs and code, match them to a ledger, and fix a cutover date and a fallback in advance — with scripts that run.
A Small Guard Script That Catches an Unattended Agent Rewriting Its Own Settings
After reading a report of an agent widening its own read-only limits by editing settings.json, I wrapped my overnight headless runs in an outside guard. Before/after fingerprints, quarantine and restore, and a hard timeout, with working code.
When an agent ends without a reason, I check the page's character encoding first
A page handed to ReadURL can end an Antigravity agent with nothing but Agent execution terminated. Here is how I tell those pages apart before handing them over, and why I now fetch and re-encode first.
When the iOS 27 Date Landed, the First File I Grepped Was AGENTS.md
iOS 27 and iPadOS 27 ship on September 14. Old version numbers linger in your source, but also in the files only your agent reads. Here is a script that counts both zones, plus the one line keyword search will never find.
Before I accept what /boost says it verified, I count what its throwaway worktree never saw
Antigravity's /boost runs its tests inside an ephemeral isolated worktree. If your build reaches for files git never tracked, that verification passed on a different tree than yours. Here is how I measure the gap first.
With scheduled agents, I now look for runs that never happened before I look for failures
My run ledger showed a 100% success rate while the evening slot had not fired for two weeks. Here is the reconciliation I now run against an expected-fire table, with measured notes on cron expansion, exit codes, and how the ledger itself gets written.
Snapshot Your Agents' Effective Scope So You Notice the Day a Default Changes
Antigravity 1.1.25 made Markdown-defined custom agents inherit the surrounding skills, rules, and subagents by default. Here is the snapshot-and-diff routine I now use to check whether an agent I meant to keep narrow quietly got wider after an update.
The Five Days Between the iOS 27 RC and Release — I Check Init Order and Entitlement Restore Before Layout
A record of how I narrow the agent's search scope during the short window before an OS release — by launch path rather than by screen. Includes the audit script I run to catch consent and ads init ordering, entitlement restore gaps, and hardcoded size branches.
How much of Antigravity's generated commit message I actually keep
Where the Review pane's generated commit message stops being enough, and where I start writing. A prepare-commit-msg hook that adds a Why trailer, plus measured behaviour during rebase, cherry-pick and revert.
Why Filename Search Misses Every Error String in Your Repo
Antigravity 2.12 improved partial filename search. Measuring name lookups against full-text search across a 2,088-file repository, the reading cost differed by 67x and error strings hit filenames only 4.5% of the time. Here is where the line actually falls.
