When an Unresponsive MCP Server Freezes Your Agent: Separate Timeouts for Connect, List, and Call
Antigravity CLI 1.1.3 closed the case where an unresponsive MCP server stalls an agent forever, by adding timeouts to connect, list-tools, and call-tool. This walks through why the three boundaries fail differently, and builds a defensive wrapper with a circuit breaker and failure-only notifications, backed by working code and a week of overnight runs.
The One File That Stops Startup: Guarding config.json Integrity Before Scheduled Runs
Antigravity 2.3.1 fixed a bug where an empty or corrupt config.json blocked startup. The symptom was fixed; the causes of corruption still live in your environment. Here is a three-layer guard — validate, snapshot, restore — that runs before a scheduled job, with working code and notes from running it nightly.
Turning Silent Auto-Approvals into Allow Rules, One Soft-Deny at a Time
In Antigravity CLI 1.1.3, headless -p stops silently auto-approving confirmation-required tools and instead soft-denies them, printing the required allow-rule name to stderr. This piece uses that output as a discovery source to build least privilege from an empty allow set upward, with a working harness and real numbers from a personal automation.
When an Unattended Run Finds Its Working Folder Owned by Someone Else
A schedule that had been green for weeks failed one morning because it could not write .git/config. The cause was ownership drift on a reused working folder. Here is how to tell apart the read-but-not-write trap, probe writability for real, and fall back to a folder you can always write.
Pour Your Unattended Run Logs into SQLite and Count Failures Across Every Run
Running Antigravity CLI on an unattended schedule leaves a growing pile of JSON Lines logs. Instead of grepping files, I pour them into a tiny SQLite database and answer 'which step fails, and when' with a single query. Here is the ingest script, six diagnostic queries, and six weeks of real numbers.
Nobody Is There to Say Yes: Writing Unified Permissions as an Unattended Contract
The v2.2.1 unified permission system assumes a person is watching. On a 3 a.m. scheduled run, that assumption quietly breaks. Here is how I declared the policy up front as an allow / deny / queue contract so an unattended agent never stalls on a prompt no one can answer.
Calling Local LLMs from Antigravity — Ollama and LM Studio Integration in Practice
Running local LLMs from Antigravity via Ollama or LM Studio: a real benchmark harness, how to confirm the model is actually on the GPU, a monthly breakeven model, and a wrapper that forces JSON output.
Antigravity Now Saves OAuth Tokens to the OS Keyring — Keeping Auth Alive in Headless Runs
In v2.2.1, refreshed OAuth tokens are saved to the OS keyring automatically. Pleasant on the desktop, but on headless scheduled runs the vault itself may not exist and auth quietly breaks. We design explicit backend selection, a safe file fallback, and per-location liveness checks.
When Successful Automation Quietly Stops Earning Its Keep: Designing for Value Decay and Retirement
A dashboard full of green success logs often hides the most dangerous kind of failure. Here is a design — with working code — for surfacing automations that keep succeeding while producing no value, and deciding whether to retire, repair, or keep them.
The Thumbnails Had Been Drifting: Catching Image-Asset Regressions with pHash and SSIM in Your Agent Workflow
After letting an agent rewrite an image pipeline, visual quality can quietly slip in ways tests never catch. This guide shows how to measure that drift with two numbers — pHash and SSIM — and block it in CI, from threshold calibration to a ready-to-run gate script and Antigravity integration.
Semantic Search Over Your Own Codebase with Gemini Embeddings and sqlite-vec: An Incremental Index Keyed on Git Blob Hashes
A build log for semantic search scoped to your own repository, using Gemini embeddings and sqlite-vec. Covers an incremental pipeline that skips re-embedding unchanged files via git blob hashes, with measured index size and query latency.
Distribution-Path-Agnostic Antigravity CLI Automation: Betting on Both the Consumer and Google Cloud Editions
The 7/1 announcement began offering the Antigravity CLI via the Gemini Enterprise Agent Platform too. Here is a design that abstracts your personal automation to run on either the consumer or Cloud edition, laid out with a wrapper and capability-detection scripts.
