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.
