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.
The Day I Stopped Splitting by Skill — Three Questions for Routing Work Between Antigravity CLI and Claude Code
An unattended job sat waiting on an approval prompt for three days without a single error line. Here is how I stopped dividing work between two agent CLIs by capability, and started dividing it by where the approval boundary falls.
Your UI Is in Japanese. Your Commit Log Isn't.
Setting your editor's display language does nothing for the language your agents write into the repository. Here is what six weeks of unattended runs actually produced, how to pin output language per audience, and a gate that catches the drift mechanically.
The Morning It Wrote Outside the Working Folder: Vetting Every Write Path in One Function
Antigravity CLI 1.1.3 closed a bug where always-proceed mode silently auto-approved writes outside the workspace. Here is a small guard that vets every write path with nothing but path canonicalization and a containment check, plus an escape-attempt test suite.
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.
Quarantining the Dependencies Your Agent Adds, Before They Install
When an agent adds a dependency overnight, nobody reviews the lifecycle scripts that run at install time. Here is how I turned the default off and built a quarantine score to let the safe ones through.
Confirm Your Unattended Runs Survived a Point Release in 30 Seconds
As Antigravity ships point releases at a fast clip, how do you stop scheduled runs from quietly breaking after an update? Here is a lightweight smoke test that detects regressions against a golden output and rolls back automatically when it diverges.
