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 built from rule-based risk classification, per-agent review markers, and a 30-second verification pass.
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.
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.
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.
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.
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.
From Gemini CLI to Antigravity CLI: Migrating Without Stopping Your Automation
Gemini CLI has been retired and the Go-rewritten Antigravity CLI is now its successor. If you have the CLI wired into CI or scheduled jobs, swapping everything at once will break your automation. Here is a concrete plan for migrating gradually, from parallel testing to full cutover.
Running Antigravity CLI Unattended: Notify Only on Real Failures
A small wrapper for scheduled Antigravity CLI runs that stays silent on success and alerts you only on failures a human needs to act on, covering exit codes, transient-error triage, and duplicate suppression.
On Cutover Day to the Antigravity CLI, Verify Production Automation by Side-Effect Equivalence, Not Output
On the day you switch from the Gemini CLI to the Antigravity CLI, verify production automation by the equivalence of side effects — files written, commits, network calls — instead of matching stdout. A sandbox parallel run and a go/no-go cutover gate, with implementation steps.
Gating Your Agent's Commits With pre-commit — Keeping Broken Changes Out of the Main Repo
How to wire up a pre-commit gate that lints, type-checks, runs fast tests, and scans for secrets the moment Antigravity's agent commits — with measured timings and the ordering that keeps it fast.
When the Antigravity CLI Stalls on a 401 During Unattended Runs
If your scheduled Antigravity CLI job suddenly stops producing output after a single 401 in the logs, here is how to separate an expired token from a silent re-login prompt and rebuild your unattended setup.
