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.
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.
When Your MCP Servers Vanish From the Chat App in Antigravity 2.0
After Antigravity 2.0 split into an IDE and a separate chat-style agent app, an MCP server I had set up in the IDE stopped showing up on the chat side. Here is why the settings scopes are separate, and how to fix it by making a single workspace-level source of truth that both apps read.
