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.
The Cleanup Step Removed the Working Directory, Not Its Contents — Making Unattended Destruction Fail Closed
An unattended cleanup step deleted the working directory itself instead of what was inside it. Here is why the mkdir -p that followed was not a safety net, and how a defensive-looking default value ended up selecting the destructive branch, with the actual verification output.
Why I Check Description Overlap Before Turning On inheritCustomizations
CLI 1.1.14 collapsed markdown agent inheritance into a single inheritCustomizations switch. Here is what happened when I actually inventoried the 47 skills in my workspace and decided the switch on description overlap rather than on context size.
When Antigravity Swaps Its Default Model, Only the Jobs You Narrowed First Survive
Gemini 3.7 Flash is now the default model for Antigravity agents. The places you never configured are exactly the places that shift silently. Here is how to inventory your default-model exposure, then split your jobs into move-now and hold, scored by how much output freedom you left open.
Android 17 Went Canary-Only, So I Gave My Agent the Silence Rules First
Android 17 dropped Developer Previews in favour of rolling Canary builds, which moved the verification deadline onto my side of the table. Here is how I handed the tracking job to an Antigravity agent by designing when it stays quiet, not when it reports.
How Far to Narrow an Agent's Choices in a 30-Category Wallpaper Classification Pipeline
Asking an agent to pick one of 30 categories per image means re-running every image the moment a definition changes. Here is the reasoning and the implementation behind switching to closed-vocabulary tags plus a deterministic rule mapping.
A Typo in agent.md Quietly Widened My Permissions — Writing a Strict Frontmatter Lint
Misspelled keys in agent.md frontmatter do not raise errors. They fall back to defaults, and for permission fields that fallback points the wrong way. Here is the failure I hit, the lint I wrote to catch it, and what the measurements showed.
After Compose-First: Choosing Which View Screens to Migrate, Ranked by Churn Instead of Count
Google has declared Android development Compose-first. Here is how I rank View-based screens for migration using git history rather than screen counts, with the scoring script I actually ran and the three places partial migration quietly duplicates state.
One Space in a Path, and Nine Commands Reported Success While Counting the Wrong Place
A single space in a workspace name sends agent-written commands somewhere else, quietly. Measurements across eleven unquoted-path forms, and the entry-point script that closes the boundary in one cd.
Android 17's Local Network Permission: Inventory Every LAN Call Site Before You Hand the Fix to an Agent
Apps targeting the new API level need explicit permission to reach the local network. A grep for private IPs found 2 of my 11 LAN paths. Here is the detector that found all 11, and how I turned its output into eleven checkable tasks for an agent.
Three Quarters of My Reference Notes Never Reached the Agent: Measuring What head Cuts Away
I fed reference notes to a scheduled agent with cat and head, and the lines that mattered were quietly cut. Here is the measurement, and how I replaced a line count with a section-level contract.
When to Hand Your Agent the Next Instruction: Waiting, Interrupting, and Queuing, Measured
Antigravity v2.3.0 added message queuing and Send Now. I measured waiting, interrupting, and queuing against the same yardstick, found that 41% of queued instructions arrive stale, and cut rework from 22% to 9% with a twenty-line stamp.
