Claude Code in Google Antigravity IDE — Full Setup Guide (2026)
About This Video
Claude Code in Google Antigravity IDE — Full Setup Guide (2026) Claude Code running inside Google Antigravity IDE is the most underrated AI coding setup of 2026 — and it takes about 5 minutes to configure. In this tutorial I show the full install, how to plan with Gemini 3 and execute with Claude, and the workflow mistakes that quietly burn your usage limits. Google Antigravity is Google's agent-first IDE with built-in Claude Sonnet support, but running Claude Code as a separate terminal agent alongside it unlocks a very different workflow: Antigravity's agent manager handles orchestration, browser verification, and artifacts, while Claude Code handles deep, surgical multi-file edits. Used together they cover each other's weak spots. In this video: — Installing Claude Code and wiring it into Antigravity's integrated terminal — Authentication options (subscription vs API key) and which is cheaper — Plan with Gemini 3, execute with Claude: the exact handoff pattern — CLAUDE.md + AGENTS.md so both agents share the same project context — Avoiding merge conflicts when two agents touch the same repo — Rate limits, cooldowns, and how to stretch your quota — When Antigravity's native agent is genuinely the better choice ⏱ TIMESTAMPS 00:00 Why this combo works 00:xx Installing Antigravity 00:xx Installing Claude Code 00:xx Authentication + first run 00:xx Shared context files (CLAUDE.md / AGENTS.md) 00:xx Plan-with-Gemini, build-with-Claude demo 00:xx Real project walkthrough 00:xx Rate limits + cost breakdown 00:xx Mistakes to avoid 00:xx Which one should you actually use? 🔗 LINKS Google Antigravity: https://antigravity.google Claude Code docs: https://docs.claude.com 💬 Which agent do you trust more with a big refactor — Claude Code or Antigravity's agent?
