Fixing spawn npx ENOENT When an Antigravity MCP Server Won't Start
Your MCP server config JSON looks correct, but Antigravity logs spawn npx ENOENT and the server stays gray. This is almost always a PATH inheritance problem, not a broken server. Here is how to diagnose and fix it.
Why Your Antigravity Agent Stops Mid-Task with 429 RESOURCE_EXHAUSTED, and How to Fix It
When you hand a long task to an Antigravity agent, it sometimes halts halfway with a red 429 RESOURCE_EXHAUSTED. That is a rate-limit or quota signal, not a bug. Here is how I diagnose the three flavors of 429 in production, and how to keep your agent from stalling on the same wall twice.
When the Antigravity Agent Says 'command not found' for node or python: Causes and Fixes
It works in your own terminal, but the Antigravity agent hits command not found. Starting from how PATH inheritance works, here are concrete fixes for nvm, pyenv, Homebrew, and WSL setups—plus how to confirm the fix actually took.
Why Antigravity Agent Edits Vanish with Auto Save (and How to Stop It)
When Antigravity's agent stream collides with the editor's Auto Save, parts of an applied diff silently disappear. This guide walks through the exact conditions that trigger it and a three-step fix you can keep across projects.
Fixing Antigravity Google Sign-in That Won't Return From the Browser
When you press Sign in with Google in Antigravity and the browser just hangs without returning to the editor, the cause is rarely a single thing. Here is how I narrow it down across four layers — callback port, third-party cookies, stale session files, and network path — using only commands I keep close on every machine.
Fixing Japanese Mojibake (Garbled Text) in Antigravity's Integrated Terminal
When git log, npm errors, or filenames containing Japanese characters turn into gibberish like 譁?ュ怜喧縺 in Antigravity's integrated terminal, the fix usually takes one or two lines per platform. Here are the Windows, macOS, and WSL2 patterns I keep running into.
Why Antigravity's Browser Sub-Agent Reads SPAs as Empty Pages — and Three Wait Strategies That Stuck for Me
When you hand an SPA dashboard to Antigravity's Browser Sub-Agent, get_page_text often returns before the real content is rendered, and the agent reports an empty page. Here is how I diagnose the symptom and the three wait strategies that have stabilized my routine.
Why Antigravity Agents Hang on ssh, sudo, and git rebase -i — Diagnosing and Permanently Fixing the Missing TTY Problem
When you ask an Antigravity agent to deploy, the terminal panel stops on 'password:' and never moves. The agent isn't broken — the shell behind it has no PTY, so interactive prompts have no one to answer them. Here's how to diagnose and remove every interactive command from your agent workflow.
Why Antigravity's Agent Keeps Referencing the Previous Repo After You Switch Projects — Diagnosis and Fix
When Antigravity carries leftover state from your previous project into a new one, the agent confidently edits files that don't belong to the current repo. Here's how to diagnose and prevent that context bleed.
Why Antigravity's AI Agent Misreads .env Values — Quoting, Whitespace, and Export Pitfalls
When Antigravity's agent writes or reads .env files, subtle differences in quoting, trailing whitespace, export prefixes, and # characters cause silent value corruption. Here are four real cases I hit in production, with concrete diagnostics and fixes.
Why Antigravity's Workspace Indexing Stalls on Large Repositories — and How to Fix It
A walk-through of why Antigravity's indexer can spin forever on a monorepo, with the diagnostic steps and fixes I use on my own 12 GB repository.
Why Antigravity Agents Hit `Permission denied` on git push, and How to Fix It for Good
Your Antigravity agent finishes the edits, tests pass, the commit message is sharp — and then git push fails with `remote: Permission to ... denied` or `fatal: Authentication failed`. Here's the diagnostic flow I actually use for multi-account, multi-PAT setups, plus the long-term fixes that keep the error from coming back.
