Best Antigravityrules & configs
Antigravity is Google's agent-first development platform — an AI IDE where autonomous agents plan, edit, run commands, and drive a browser on your behalf. It runs Gemini 3 Pro by default with model optionality (Claude and GPT-OSS also supported), and is free in public preview. Per-project guidance lives in AGENTS.md (the cross-tool convention Antigravity reads alongside GEMINI.md) plus workspace rule files under .agent/rules/.

What is Google Antigravity?
Antigravity is Google's agent-first IDE. Instead of just autocompleting lines, it lets you spawn and orchestrate autonomous agents that plan, edit files, run terminal commands, and control a browser. It runs Gemini 3 Pro by default and is free during public preview on macOS, Windows, and Linux.
Where does Antigravity read project rules from?
Antigravity reads AGENTS.md at the repo root — the same cross-tool convention Codex uses — plus GEMINI.md for Antigravity-specific overrides and .agent/rules/*.md for scoped workspace rules. If you're unsure where a rule belongs, AGENTS.md at the root is the safest, most portable home.
Can I reuse my Codex or Gemini CLI rules in Antigravity?
Often yes. Antigravity reads the same AGENTS.md file that Codex and other agentic tools use, and GEMINI.md is shared with Gemini CLI. Many RuleSell listings ship AGENTS.md so one file covers Antigravity, Codex, Claude Code, and Gemini CLI at once.
Which models does Antigravity support?
Gemini 3 Pro is the default, with generous public-preview rate limits. Antigravity also supports model optionality — Anthropic's Claude and OpenAI's GPT-OSS run alongside the Gemini models — so you can pick the model per task.
Are RuleSell's Antigravity rules free?
Yes — every listing is free to download during beta. Paid publishing with Stripe Connect payouts opens after beta, and original authors keep the majority cut.
