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.
The work-root guard I run before letting an agent near several repositories
When several repositories share one machine, an agent's working root is remarkably easy to mix up. Here is a small guard that compares resolved paths, tested against seven inputs.
Git Tracks the File, but Your Agent Can't See It. Here's Where It Drops Out
An agent's code search returned two files. git grep returned six. I traced the three paths that quietly drop tracked files out of search, measured them on a synthetic repo and a production one, and worked out how to spot the gap in a single line.
