374 exclusive articlesAre You Actually Using Every Permission You Granted? Tightening Antigravity's Unified Permissions from Real Usage Logs
Once you flip a unified permission policy to 'allow everything,' unused grants quietly pile up. This is the grant-to-usage reconciliation loop: match granted permissions against your action logs, revoke what was never exercised, and narrow what's too broad — with working TypeScript and real numbers from solo operation.
An Agent's ORM Code Made p95 Five Times Slower — Measuring Query Counts and Blocking Them in CI
N+1 queries slip past code review because the code looks correct. Here is a CI gate that measures query counts and judges them by their slope against input size, with working code and real numbers.
You Can Measure a Request Before You Send It — Sizing Agent Tasks by Working Backward from Rework Rate
When an Antigravity agent returns code that misses the mark, the cause is rarely the wording of the prompt. It is the size of the task. Here is a Python scorer that grades a request before you send it, plus what happened when I scored 80 past requests against their actual rework outcomes.
Tracing Why an Agent Wrote That Line Six Months Ago — Commit Granularity and Provenance Trailers
When an agent packs 14 files and 800 lines into a single commit, git blame tells you nothing six months later. Here is how I split commits at intent boundaries, recorded provenance as machine-readable Git trailers, and built a one-command path from a blamed line back to the design decision behind it.
When Your Agent's Files Vanish Into .gitignore — A Pre-Commit Detection Gate
When an agent writes files that match .gitignore, the diff review looks perfect but nothing lands in the commit. Here is a gate script that catches ignored build output before you push, plus the tuning it needs.
Deciding When to Stop a Staged Rollout, Before You Have To — Agents Watch, I Halt
Field notes on building a Google Play staged-rollout watcher with Antigravity. Crash rate as a ratio to baseline, delayed ANR evaluation, and an explicit insufficient_data verdict — with the halt action kept in human hands.
Background Refresh May Never Run — Measuring Execution Opportunity and Redesigning Around Freshness
Scheduling a BGTaskScheduler or WorkManager job is a request, not a guarantee. Here is how I instrumented execution opportunity, defined freshness as an SLO with p50 and p90 targets, and rebuilt the update path into three layers that hold up when background work never runs.
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.
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.
Building a Live Wallpaper That Doesn't Drain the Battery — Designing the WallpaperService Render Loop Around a Power Budget
Live wallpapers quietly burn battery because they keep drawing when nothing is visible. Here is the WallpaperService.Engine design I used to cut power draw by roughly 60% in a real wallpaper app, built around visibility, idle, and thermal gates.
Never Miss a Managed Agent Completion: Pairing a Serverless Receiver with Polling Reconciliation
A cloud Managed Agent can finish while you are not watching, and the webhook that should tell you can quietly fail. Here is a serverless receiver on Cloudflare Workers paired with polling reconciliation, and a state machine that recovers every completion within minutes.
Keep the Self-Debugging Agent Away From Live Ads: Three Layers Against AdMob Invalid Traffic
When Antigravity 2.0's real-browser self-debug renders a live AdMob unit, every pass counts as an impression, and Google may read it as invalid traffic. Here is a three-layer setup, with measurements, that keeps the agent from ever touching a production ad.
Protecting Your Agent Stack's Known-Good State with a Single Lockfile — Change-Budget Design for an Era of Simultaneously Moving Parts
When the IDE build, CLI, model, and dependencies all move at once, you can no longer tell which one caused a regression. Here is a change-budget design that pins your known-good state to one lockfile, with working code and operational logs.
Make the Self-Debugging Agent Walk the Logged-In and Post-Paywall Screens
By default, Antigravity 2.0's real-browser self-debug only sees the logged-out free view and reports success. To catch billing regressions, inject an authenticated session and paid state into the agent's browser and force coverage with assertions.
Where Context Should Live — Routing It Across Persistent, Per-Task, and In-the-Moment Layers
Antigravity 2.0's /btw lets you inject context mid-task. But unless you separate what belongs in a persistent rule, a task instruction, and a passing aside, your agent's accuracy actually drops. Here is a design for three context layers.
When Nobody Reads Your AI Code Reviewer Anymore — Field Notes on Measuring Actioned-Rate
Our production AI code-review agent quietly went hollow over six months. When the team started silently resolving every comment, we instrumented actioned-rate and false-positive rate to bring it back. These are the field notes.
When a Stable Line and a Feature Line Ship Together, Which Build Should a Solo Operator Ride?
By shipping a 2.0 (stable) line and a 2.1 (feature) line in parallel, Antigravity now asks solo developers to decide which one to ride. Here is a design for selecting and switching builds without breaking your automation.
Paid, but the Ads Won't Go Away — Closing a StoreKit 2 Transaction.updates Launch Race with Antigravity
How I traced a StoreKit 2 launch race that dropped transactions arriving right after startup, pinned the listener to the app's lifetime instead of a view's, reconciled with currentEntitlements, and let Antigravity turn it into a StoreKitTest regression suite.
When AppEnum Breaks in App Intents — Designing EntityQuery so Siri Can Pick From a Catalog That Grows Every Day
Writing an App Intents parameter with AppEnum works fine while the options are fixed, but it cannot survive content that grows daily. Here is the AppEntity + EntityQuery design that lets Siri and Shortcuts correctly pick from a dynamic catalog, including identifier stability and Spotlight pitfalls.
Where to Put Evidence and Approval When Your Agent Self-Debugs in a Real Browser
Antigravity 2.0 launches a real Chrome mid-build, clicking buttons and taking screenshots to self-heal. It is fast, but shipping that as-is is risky. Here is how to capture evidence and draw the approval boundary.
When Universal Links Break Silently — Catching Association Drift with an Agent-Run Verification Gate
Universal Links and App Links fall back to the browser with no error when your association files or entitlements drift apart. Here is a design that generates the files from one source of truth and hands weekly and pre-release checks to an agent.
Before You Let Siri Run an Agent-Written App Intent — Classify by Side Effect and Gate the Destructive Ones
Letting Siri or an assistant run an Antigravity-generated App Intent without a gate means a destructive action can fire from a single voice command. Here is how I classify intents by side effect, gate the irreversible ones, and catch missing gates before push.
When CI Passes but App Review Rejects Your Screenshots — Field Notes on Measuring the Freshness of Your Validation Rules
Store asset validation can pass in CI and still get rejected in review, because the rules themselves go stale. Move store specs into a freshness-dated contract file, then add locale overflow checks and perceptual diffs.
The Failure That Never Shows Up in Your Crash List — Collecting ANR Traces with ApplicationExitInfo and Handing Triage to an Agent
ANRs never reach your crash handler. Here is how I collect them at startup with ApplicationExitInfo and hand triage to an Antigravity agent, with five weeks of real numbers.
Riding Two Release Lines — Splitting Antigravity's 2.0 and 2.1 Tracks Between Unattended and Interactive Work
On July 1, Antigravity published 2.0-line and 2.1-line builds side by side. Here is a version policy that keeps unattended automation on the stable line and interactive work on the feature line, with a declaration file and drift detection.
Catching Download Size Regressions Before Submission Day — A Weekly Agent Gate for AAB/IPA Size Budgets
Mediation SDKs and bundled assets quietly inflate download size. A design for size ledgers, budget gates, and agent-driven delta attribution using bundletool and App Thinning reports.
Stop Treating Dependency Updates as a Monthly Chore — Weekly Agent Runs with Semver Risk Triage and Verification Gates
Move from batch-updating 47 stale packages at once to a weekly agent-driven routine: semver-based risk tiers, a playbook YAML, hallucination-proof changelog reports, and a lockfile diff gate.
Stop Dreading the Rejection Email: Triaging App Store Review Feedback with an Antigravity Agent
A working setup for feeding App Store rejection notices into Antigravity, classifying them against a guideline playbook, and gating resubmission with an Info.plist lint — with real turnaround numbers.
Handing Off IDE Work to the Chat Agent: Passing Context Through a File After the Two-App Split
Since Antigravity 2.0 split into an IDE and a chat-style agent app, context you build up in one does not carry into the other. Here is a file-based approach that makes a single file in your repo the source of truth for handoff, with a schema, a validation script, and a way to pin it with a Guide skill.
Parallel Agents Multiply Artifacts Too — Designing Lifespans and Cleanup for Intermediate Outputs
Worktrees, screenshots, temp branches — parallel agents leave debris at parallel speed. A design for defining artifact lifespans and automating cleanup without ever destroying uncommitted work.
Before You Let an Agent Own Your Tests — Deciding How Fixtures and Seed Data Live
Agents will happily edit test data until the tests pass. A practical defense built on fixture ownership, deterministic seeds, and anonymized subsets of production data, with working scripts.
Turning Last Night's Failed Runs into Tomorrow's Prevention — Designing a Postmortem Feedback Loop
Stop letting unattended failures end at a notification. A concrete design for classifying failures and feeding fixes back into Guide skills, gates, and schedules, with measured recurrence rates.
When the Tech-Debt Score Drops but the Same Files Keep Breaking — Field Notes on Instrumenting Fan-in and Churn
Letting Antigravity's architecture agent score technical debt is not enough — bugs often recur in the same files after refactoring. Here is how we instrumented the fan-in times churn that static complexity misses, and reconciled the score against real incidents.
Distribution-Path-Agnostic Antigravity CLI Automation: Betting on Both the Consumer and Google Cloud Editions
The 7/1 announcement began offering the Antigravity CLI via the Gemini Enterprise Agent Platform too. Here is a design that abstracts your personal automation to run on either the consumer or Cloud edition, laid out with a wrapper and capability-detection scripts.
Don't Build Your Own Peak: Time-Spreading Background Agent Schedules
Antigravity 2.0's desktop auto-schedules tasks in the background. Convenient, but cluster them at round hours and you build your own peak, and the late-night jobs fail together. Here is a design that spreads times and bans overlap, with real results.
It Worked Interactively but Went Silent Overnight — Making an Antigravity Agent Behave the Same in the Desktop and the CLI
An agent that runs perfectly in the Antigravity desktop app but does nothing when you schedule it through the CLI. This walks through absorbing the gap between interactive and unattended runs across four points — approvals, context, secrets, and runtime — with working code and a preflight check, so one definition behaves identically on both.
Detecting and Fixing Drift Between a Guide Skill and Your Code
Pin a procedure into a built-in Guide skill and it gets left behind when the code later changes. Here is an operational design that machine-checks the things a Guide references, catches drift early, and keeps the Guide thin.
Systematize Pre-Release Checks for Sound-Playing Apps with Waveform Rendering and Agents
The 6/26 update let Antigravity render audio files. Drawing on years of shipping sound in healing apps, here is a design that folds loudness, clipping, length, and silence checks into an agent verification loop, with the actual scripts.
Measure Before You Trim: A Context Ledger for Antigravity CLI Token and Latency Costs
Prompted by the ~70% token reduction reported for the Android CLI agent, I built a thin wrapper and a weekly review to measure my own agent runs. Here is how I replaced whole-file context with line ranges and cut wait times.
Don't Let Your Automation Lean on AI Ultra's 5x Ceiling
The $100/month AI Ultra plan raises Antigravity's usage limits to 5x AI Pro. But if you architect automation around that ceiling, it collapses the moment you drop back a tier. Here is a limit-independent degradation design, with the real pain points.
Faster Substring Search Changes How You Should Let Agents Explore Code
The 6/26 update made substring search noticeably faster. Rather than treating it as a comfort improvement, here is how to redesign the way agents explore code, budget context, and verify their targets, with measurements from indie development.
Keeping Naming and Formatting Stable When Your Model Falls Back
When a model falls back mid-run, an agent's naming conventions and formatting drift quietly. Here is how I enforce a model-independent style contract plus a drift probe to keep output consistent.
When the Android CLI Got 3x Faster and Cut Tokens by ~70%, the Right Move Was More Verification Per Change — Not More Parallelism
Reading that the Android CLI agent runs ~3x faster while using ~70% fewer tokens, my first instinct was to ask how many runs to parallelize. But a faster agent doesn't change how much work ships — it changes where the queue forms. This walks through why, sizes the new bottleneck (review and verification gates) with Little's Law, enforces a WIP cap with a working Python admission controller, and reinvests the freed budget into depth per change — with measured results.
The Built-in Guide Skill Is Only Advice — Pair It With a Gate That Mechanically Rejects Antigravity's Output
The v2.2.1 built-in Guide skill raises how often the agent complies, but it is still probabilistic advice. Here is the design for a deterministic gate that reliably stops the violations that slip through, with working code and measured results.
When Every Antigravity-Written Test Is Green but the Same Bug Comes Back — Field Notes on Measuring Hollow Assertions
Your AI-written tests all pass, coverage is high, yet the same defect returns to production. The cause is over-mocking and tautological assertions. These are field notes on using mutation testing as ground truth to measure what your tests actually protect, and to fix it operationally.
When the Agent Hands You 1,400 Replacements in One Commit, Ask for Batches Instead
Ask Antigravity to run a large codemod and you can get back one unreviewable commit. Here is a small design — ast-grep rules plus a verified batch driver — that splits a mechanical replacement into the machine's job and the human's check, with working code.
The App Open Ad Antigravity Wrote for Me Fires Every Time I Return From My Own Paywall or Rewarded Video
Ask Antigravity to add an App Open ad and it shows one the instant you return from your own rewarded video or the Google Play purchase sheet — which also brushes against AdMob policy. Here is a foreground arbiter that records why the app came back, with working Kotlin and a verification matrix.
Running Xcode 27's Agent and Antigravity Side by Side: Designing the Work Boundary for iOS
With Xcode 27 bringing agentic coding into the IDE itself, iOS development now has two code-writing agents over one repository. Here is a practical design for keeping a single source of truth and splitting work across spec, implementation, and verification.
When Parallel Sub-Agents Fight Over One API's Rate Limit: A Shared Token Bucket That Caps the Aggregate
Run Antigravity 2.0 dynamic sub-agents in parallel and each one hits the same external API independently, pushing the aggregate rate over the limit and triggering cascades of 429s. Here is a shared token bucket that caps the aggregate proactively, with working code through a Redis version.
Keep an Agent Running on a Nearly Empty Quota — Designing Graceful Degradation
When the monthly quota is almost gone, stopping the agent entirely is not the only option. Here is how to design graceful degradation — dropping capability one tier at a time while still producing valuable output — with policy code.
When Your Antigravity Agent Opens a PR That Just Says "Update files" — and a Gate That Forces a Reviewable Summary
Pull requests opened automatically by an Antigravity agent tend to carry empty descriptions like "Update files." Here is a validation gate, with working code, that estimates risk from the diff and rejects vacuous descriptions so a human can actually review them.
Spotting Agents That Are Alive but Stuck — Designing a Progress Heartbeat and Watchdog
The process is alive but the work isn't moving — the nastiest state for a background agent. Here is how to switch from liveness to progress monitoring to detect it, and how to stop it safely, with working code.
When Background Agents Run Twice — Stopping Double Execution with Leases and Fencing Tokens
The same scheduled job fires from two machines at once and they overwrite each other's output. Here is how to stop that failure mode at the root in Antigravity 2.0 background agents, using leases and fencing tokens, with working code.
When Your Antigravity-Written Tests Only Look Green: Measuring Effectiveness with Mutation Testing
Tests written by an Antigravity agent can pass and still fail to catch the bug that matters. Here is how to measure their real effectiveness with mutation testing and only adopt tests after they kill the surviving mutants — with working code.
When Antigravity Skips Parts of a Long Attached PDF — and a Gate That Forces It to Cite Sources
How to handle the case where Antigravity answers confidently from a long attached PDF but quietly skips a clause. With working code: a prompt that forces citations, and a gate that verifies each cited quote actually exists in the PDF.
Adding Mediation Partners Quietly Starved My iOS Attribution — Reconciling SKAdNetwork IDs Across Four Apps
I added mediation partners but iOS revenue barely moved — the cause was missing SKAdNetwork IDs in Info.plist. Here is how I reconciled SKAdNetworkItems across four apps, using an Antigravity agent as the matcher while keeping the revenue decisions by hand.
A Review Gate Design for Safely Folding Parallel Agents' Diffs into One Branch
Antigravity 2.0 made running multiple agents in parallel practical, but verifying each agent's output and integrating it into one branch is left to you. Here is how to build a diff-level review gate in stages, with judgment criteria and scripts.
It Did Things I Never Asked For — Binding an Agent's Task Scope With a Contract
Ask it to fix a button color and you get a refactor, renames, and a dependency bump too. This is a scope problem, not a permission one. Here is a contract that stops at the scope boundary and asks.
When Streaming Works Locally but Arrives All at Once in Production — Field Notes on Proxy Buffering and Silent Stalls
Stream Gemini through Antigravity over SSE and it flows token-by-token on localhost, then freezes for seconds and dumps the whole answer in production. Field notes on measuring the stall first, then killing proxy buffering, idle disconnects, and reconnect-driven double generation.
Where to Start Reading an Unattended Agent's Changes — A Digest for Re-Entry
How do you review the pile of changes an unattended agent left overnight? Not the full diff, not the chat log — a re-entry digest grouped by risk class.
Turning Faster Substring Search into Solid Grounding for Agents in Large Repos
Antigravity's substring search got faster. Rather than stopping at perceived speed, here is how to wire it into a search design that hands agents exactly the right context in a huge codebase, with concrete steps and pitfalls.
The Day My Own Skill Stopped Firing — When the Built-in Guide Skill Collides With Yours
Since the built-in Guide skill arrived, custom skills started getting skipped or double-fired. Here is how to observe which skill is chosen, and how to settle the conflict through descriptions and naming.
Treating Built-in Guide Skills as Design Assets, Not Throwaway Prompts
Antigravity v2.2.1 added built-in Guide skills. Here is a concrete structure and set of judgment calls for running them as version-controlled, shared design assets instead of one-off instructions.
Prune an Antigravity plan before you approve it
Instead of approving a Planning-mode plan wholesale, cut the one risky step and keep the rest. A field-tested look at partial plan editing from a solo developer's desk.
The Day the Article I Asked It to Format Became the Agent's Instructions
When you run an unattended content-formatting pipeline with Antigravity CLI, instruction-like text buried in the file you are processing can hijack the agent. Here is how I separate the instruction channel from the data channel and add an output-scope acceptance gate to reject anything out of bounds.
Before AI Studio's Gradle and AGP Versions Quietly Break Your Existing App
When you drop an AI Studio-generated Kotlin/Compose screen into an existing Android app, the AGP, Kotlin, and library versions drift and the build breaks silently. Here is how to pin a single source of truth with a version catalog and add a gate that inspects the generated declarations at the import boundary, with measurements and code.
Before Desktop and CLI Drift Apart: Put Agent Steps in One Versioned File
As Antigravity 2.0 multiplies entry points across desktop, CLI, and SDK, the instructions for the same task slowly diverge per surface. As an indie developer running several sites on autopilot, I lay out a design that consolidates the steps into a single versioned file each surface merely reads.
Before Your dynamic sub-agents Branch Out Too Far — Designing a Depth Budget and Fan-out Cap
Antigravity 2.0's dynamic sub-agents can spawn their own sub-agents at runtime. Handy, but without depth and fan-out control they can burn through your quota overnight. Here are three guards, with concrete code.
Keep a Tamper-Evident Audit Log of Your Autonomous Agent's Actions
To record the decisions and actions an Antigravity agent takes autonomously in a form you can trace and verify later, design an append-only audit log whose hash chain detects tampering. Includes the implementation.
Pass Your Agent's Structured Output Downstream With Schema Validation and Bounded Repair
Before the JSON an Antigravity agent returns flows straight into downstream automation and causes an incident, build a safe boundary with JSON Schema validation and a turn-limited repair loop. Includes the implementation.
Rotate Keys Without Stopping an Unattended Agent: An Overlap-Window Design
API keys and tokens are worth rotating on a schedule before they leak. But an unattended agent goes quietly dead the moment auth breaks during the swap. As an indie developer running several sites on autopilot, I lay out an overlap-window design that rotates keys without downtime.
When a Local iOS Build Passes but CI's TestFlight Upload Rejects the Signature — Field Notes on match Code-Signing Drift
Running fastlane match on CI can produce builds that succeed while only the TestFlight upload fails on signing. These field notes show how to diagnose the certificate/profile drift reproducibly, lock CI to readonly, and add a pre-upload gate that stops bad signatures before they reach Apple.
Pin Your Agent's Output With Golden Snapshots Before Switching Models
When Antigravity's engine moves to Gemini 3.5 Flash, an agent's output can drift silently. This walks through a golden-snapshot regression gate that catches the drift, with the actual test code and a migration-day checklist.
When Your Agent Automation Breaks: How Many Minutes to Recovery?
As Antigravity 2.0 adds desktop, CLI, and SDK surfaces, the things you must restore after a failure multiply too. As an indie developer running several sites on autopilot, I lay out a three-layer recovery design covering credentials, definitions, and state, plus a monthly restore drill.
Why Antigravity Agents Build Your Xcode Project Fine One Day and Break It the Next on a Synced Folder
Put an Xcode project inside a Dropbox-synced folder, hand it to an Antigravity agent, and builds start passing and failing at random. Here is the real cause — sync daemon versus build — and how to fix it with xattr exclusion and a conflict-copy preflight.
Turning a throwaway prompt into a reusable sub-agent
When a one-off prompt to an Antigravity 2.0 dynamic sub-agent works beautifully, it usually vanishes into your chat history. Here is how to capture it as a reusable definition, with the actual file layout and the distillation steps.
Hand Over Generation and Shipping, but Never the Signing Key — Designing Key Custody and Handover for an AI-Driven Pipeline
Even in an era where AI Studio and Antigravity take over everything from generation to internal-test shipping, the app signing key is in a class of its own. Lose it, and that app can never be updated again. As a solo developer who has run several apps for years, here is how I design key custody — separating the upload key from the app signing key, storing it, and planning the handover for the worst case.
Green in the Embedded Emulator, Broken on the First Real Device — Putting a Parity Gate on AI-Generated Compose Apps
AI Studio now generates Kotlin/Compose apps from a prompt, runs them in an embedded emulator, and pushes them to a real device over USB — all from one screen. Yet a screen that passed in the emulator can break the first time it lands on a real phone. As a solo developer running several apps, here is how I put a gate that catches device parity issues before they ship.
Designing MCP Tool Output So It Doesn't Flood Your Agent's Context
When a custom MCP server returns large results in one shot, your Antigravity agent quietly degrades. Field projection, pagination, resource_link, and an output budget keep context from overflowing — shown with concrete TypeScript and measured numbers.
Splitting a Giant Antigravity Diff Into Meaningful Commits
Are you committing the agent's 400-line diffs as a single blob? Here is a practical workflow, with scripts, for re-splitting an unreviewable bulk commit into one concern per commit.
An Agent Granted 'Watch an Ad to Unlock a Wallpaper' Entirely Client-Side — Re-Verifying Reward Grants with AdMob SSV
I asked an Antigravity agent to wire up 'watch a rewarded ad to unlock a wallpaper,' and it returned an implementation that wrote the unlock flag client-side only. Here is why that is not enough, how I re-verified the reward grant with AdMob server-side verification (SSV), and how I stopped double grants too.
Before a Major Update Silently Breaks Your Overnight Automation — Designing a Staged-Adoption Canary Gate
After a major update dropped my unattended run success rate from about 98% to 63% overnight, I built a staged-adoption gate that freezes the working setup, verifies a new version against a golden output in an isolated profile, and only then adopts it. Here is the design with bash and Python.
When Xcode Cloud's Free 25 Hours Quietly Run Out at Month's End — Field Notes on Measuring and Defending Compute Time
Before Xcode Cloud's free compute allowance drains at month's end and your builds sit queued, measure where it goes. Practical field notes on pulling usage from the App Store Connect API, stopping wasteful builds early, and trimming test runs to keep CI inside budget.
A Translated Line Had Quietly Reverted to English — Guarding String Resources an Agent's Refactor Touched
Let an agent tidy your values folder and translated strings can silently revert to the source text. Here is a design and implementation that treats the default locale as the source of truth, reads every other locale as a diff, and blocks only dropped keys, reverted translations, and broken format arguments at pre-commit.
The Day Rolled Over and Yesterday's Wallpaper Came Back — Designing Date Boundaries Instead of Trusting an Agent's Time Code
A record of redesigning a daily-rotating wallpaper feature that showed yesterday's pick after midnight for some users and switched twice in one night for travelers. I separate the device clock, time zone, and daylight saving time into three distinct failure sources, show how to define a stable day key, defend reward boundaries against a rewound clock, and test it all with an injectable clock — from a solo indie developer's point of view.
Every Favorite Tap Was Redrawing Every Visible Wallpaper — Stopping Needless Recomposition in Compose, Measured
A record of fixing a wallpaper grid where toggling a single favorite recomposed every visible thumbnail. Covers turning on Composition Tracing to measure first, tracking the unstable parameter down, stabilizing the data model, handling lambdas and derived state, and comparing recomposition counts before and after from an indie developer's view.
Combining All Four Antigravity Surfaces in One Project — Up to Running Your Own SDK Agent
How to split a single project across Antigravity 2.0, CLI, IDE, and SDK, and how to bridge between them — from diverging on design to converging on production, all the way to running a small custom agent with the Python SDK, with implementation included.
The Day Generation, Device, and Internal-Test Shipping Became One Step — What I Refused to Hand Over
AI Studio now turns a text prompt into a Kotlin/Compose app and carries it through the emulator, a real device, and Google Play's internal test track from one screen. Behind that convenience sits a question: how much of the moment of shipping do you hand to the machine, and what do you keep in your own hands? Here is where I draw the line as a solo developer running several apps, and the implementation that holds that boundary.
Three Paths Were Each Picking Their Own Number — Deriving versionCode From a Single Source So Releases Stop Stalling
Now that AI Studio can generate an app from one prompt and push it straight to Play's internal testing track, three paths — you, CI, and the agent — each allocate versionCode on their own and collide. Here's how to derive the number from a single source and add a pre-upload guard, with working code.
Before Your Antigravity Agents Fight Over the Same File — Ownership Manifests and Conflict Detection
Multi-agent workflows do not break at the design stage. They break at runtime. Here are the field notes: an ownership manifest that pins each agent's editable region, a git-only conflict detector, and a three-part handoff contract.
When an Overnight Local Agent Crawls by Dawn — Keeping Ollama's Latency Flat by Working Backward from Context Length
Why each step of a long-running local agent gets heavier toward the end, how to measure it from Ollama's timing fields, and how a fixed num_ctx plus a rolling summary keep per-step latency flat.
Antigravity 2.0, CLI, IDE, SDK — Weaving All Four Surfaces Through a Real Project
Antigravity ships as a desktop app, a CLI, an IDE, and a Python SDK. Beyond picking one, this guide shows how to weave all four across a single project — with a headless-execution wrapper for automation, plus the cost and migration traps to sidestep.
Running Pre-Release Checks Without Opening the IDE — Designing the Android CLI as the Verification Gate of an Unattended Pipeline
How to slot Android CLI v1.0 into an unattended pipeline as its verification gate — three layers of checks, an exit-code contract, and a density-by-locale matrix, sized for an indie developer's day-to-day.
Before a Stray Instruction in a Fetched Page Drives Your Unattended Agent — Tainting Inputs to Downgrade Capabilities
So an unattended agent that reads external pages or PDFs can't be hijacked by an instruction hidden inside them: track the taint of every input and automatically downgrade side-effecting tools. With working Python and real operational numbers.
My Daily Wallpaper Widget Stopped Updating — Measuring WidgetKit's Reload Budget and Rebuilding the Design
A widget that was supposed to rotate the wallpaper every day froze after a few days. Here is how I measured WidgetKit's timeline reload budget and extension memory limit, then rebuilt the design around a single daily timeline.
The Review Prompt Fired but Nothing Appeared — Designing Around Play In-App Review's Quota and No-Show Guarantee
Play In-App Review's launchReviewFlow can succeed without ever showing a dialog. This walks through the three traps — quota, no display guarantee, and silent testing — and the engagement-based trigger design that fires at the right moment without colliding with ads, with steps to have Antigravity implement it.
When StoreKit 2 Users Say They Paid but Can't Access — Field Notes on Subscription Entitlement Drift
StoreKit 2 subscriptions are harder to operate than to implement. This is a record of the drift between currentEntitlements, subscription.status, and server notifications — and the reconcile logic that finally stopped the support tickets.
When Only the Japanese Turns to Tofu in Your Share Image — Fixing next/og CJK Fonts with Antigravity
In next/og's ImageResponse, the Japanese title renders as empty boxes while English looks fine. Here is the real cause (Satori cannot read woff2), a complete edge implementation that pulls a TrueType subset via Google Fonts css2?text=, and how to get Antigravity to fix it the first time.
When the Default Model Changes Underneath You: Pinning and Diff-Gating Scheduled Runs
Antigravity 2.0 promoted Gemini 3.5 Flash to the default fast model. It is a welcome upgrade, but any scheduled run that leaned on the default starts producing subtly different output one morning. Here is how I pin the model explicitly, fingerprint the output, and gate drift, sized for a solo developer's pipeline.

Why an Android app stutters on launch only right after install or update, explained through JIT and Cloud Profiles, plus a measured walkthrough of cutting cold-start time with Baseline Profiles — from building a Macrobenchmark harness to staged rollout, from an indie developer's perspective.
Precedence for Nested AGENTS.md: A Merge Design for Many Projects in One Workspace
Put several projects in one workspace, each with its own AGENTS.md, and which instruction the agent follows turns ambiguous. Root and per-project rules quietly collide; one wins, or both blend. Taking 'closer is stronger' as the base rule, this designs a merge that distinguishes overriding from appending, with working Python and field notes.
Strip Secrets Out of the Agent Logs You Keep: Designing a Redaction Layer
Once you start keeping logs from unattended agents, a token or API key eventually lands in them in plaintext. Rotating the key doesn't unmake the leaked log. This designs a redaction layer that reliably drops secrets right before the write, going beyond regex to register known secrets and mask them for certain, with working Python and field notes.
Scope the MCP Tools You Hand an Agent: A Least-Privilege Allowlist Design
As you add MCP servers to Antigravity 2.0, the set of tools every agent can reach quietly grows into an all-you-can-eat buffet. An agent that only needs to read files seeing delete and deploy tools is an accident waiting to happen. This walks through a least-privilege design that scopes tools per agent role, denies at call time, and gates destructive operations behind a second step, with working Python and field notes.
It Only Crashes in Release — Tracking Down When R8 Full Mode Broke My Gson Mapping
It works in debug but crashes only in release. This walks through the R8 full-mode pattern that breaks Gson reflection, how to reproduce it locally, deobfuscate the stack trace, and write the smallest keep rules that fix it.

Your Antigravity Custom Tools Don't Break by Design — They Break on Re-execution: Field Notes on Idempotency and Error Contracts
Once you add a custom tool to an Antigravity agent, the real production problem is re-execution and duplicated side effects. Here are the idempotency keys, error contracts, health gates, and tool-sprawl checks that actually held up in practice.
Stop Hard-Coding Your Agent Concurrency: Let It Tune Itself From What It Observes
When you run several Antigravity 2.0 agents in parallel, a single fixed concurrency number is wrong twice: it stalls at 429s during the day and idles capacity at night. Here is an adaptive design borrowed from TCP congestion control — additive increase, multiplicative decrease — that moves your concurrency from observed signals, with working Python and field notes.
The Back Button Showed an Interstitial Sometimes, Not Others — Rewriting Nested ifs Into a List of Independent Guards
Interstitial display on back press was unstable because nested if statements hid the priority between conditions. Here is how I split it into reason-returning guards and generated tests from a decision table.
Taking Stock of the Dependencies Your Agent Added — A Design for Keeping License and Provenance Traceable
A few months of letting agents work, and your package.json quietly grows dependencies you don't remember adding. Here is a design for taking stock — recovering what was added, when, and why, in a form you can still trace later.
Letting a Background Agent Work Overnight Without Regretting It by Morning — Guardrails for Unattended Runs
When you hand overnight refactoring to Antigravity's Background Agent, the morning brings as much anxiety as convenience. From three angles — blast radius, completion criteria, and detecting silent regressions — here are the guardrails that let me run unattended jobs with confidence.
Piping Antigravity CLI's JSON Lines Output Into My Own Script — Notes on Partial Lines and Exit Codes
Feeding Antigravity CLI's machine-readable JSON Lines output into my own script broke with JSONDecodeError roughly one run in three. Here are the three traps — partial lines, exit codes, and stderr bleed — and the line-buffered consumer that finally made it stable.
Keeping Unattended Agent Run Logs Long Enough to Debug — Without Filling the Disk
A scheduled agent is only fixable if you can reconstruct why it failed. Here is how to keep run logs around without filling the disk — tiered retention, schema-versioned records, and a compaction job — drawn from running four sites on autopilot as an indie developer.
A Few Low-Density Phones Lost Their Bundled Wallpaper — The drawable vs nodpi Boundary in Play's Density Splits
App Bundle density splits will happily split images that should never be split, dropping a static resource on one density bucket only. Here is how I reproduced it with bundletool and fixed it by moving to drawable-nodpi or disabling density split — with the decision criteria.
Feeding Store Review Guidelines as a PDF to the Agent to Build a Per-App Pre-Release Checklist
Using Antigravity v2.1.4's PDF attachment, this walks through reading the App Store and Play review guidelines into the agent as context and turning them into a pre-release checklist tied to your app's actual features.

Scheduled agents fail silently overnight and the work simply vanishes. Here is how to catch those failures with a dead-letter store and a staged requeue, drawn from running four sites on autopilot as an indie developer.
Designing Safe Background Tasks with the Managed Agents API
Antigravity 2.0's Managed Agents API launches an agent in an isolated Linux environment with a single API call, handling reasoning, tool use, and code execution. Convenient, but left unattended it invites runaways and cost overruns. Here is a design for running it safely as a background task.
More Agents Won't Speed Up Every Part of Your Pipeline — Designing the Parallel/Serial Line
Antigravity 2.0's parallel multi-agent execution is powerful, but adding agents doesn't make everything faster. Here's how I decide which work to parallelize and which to keep serial, derived from invariants and a dependency graph, with examples from running several sites as a solo developer.
When CLI, Desktop, and SDK Share One Agent Harness: Designing for Consistent Behavior
Now that Antigravity's CLI, desktop, and SDK share one agent harness, here is how to separate what stays consistent from what differs by environment, and how to align behavior with smoke tests and a version-tracking habit.
Your Antigravity Sandbox Isolates Multi-Agents Less Than You Think — Notes on Containing the Blast Radius
An Antigravity sandbox gives you the feeling of isolation, but isolation leaks through three real gaps: shared volumes, over-broad allowed domains, and approval fatigue. Field notes on plugging the leaks, containing the blast radius by design, and proving isolation holds with tests.
How to Orchestrate Multiple Agents: Drawing the Line Between Parallel and Serial Work
Antigravity 2.0 brings true parallel execution across multiple agents. But making everything parallel does not make it faster. Which work should fan out in parallel, and which should stay serial? This is an orchestration design that does not fall apart, viewed through dependencies and contention.
