Monitor Antigravity with FrontierStack

Antigravity is Google's agentic development platform: an IDE, a desktop app and the Antigravity CLI, agy, which replaced Gemini CLI for personal Google accounts on 18 June 2026. FrontierStack detects agy and its version on this Mac or over SSH and installs or updates it with Google's script. It also runs agy doctor, and agy plugin import gemini to bring Gemini CLI extensions and MCP servers across. The MCP pane adds FrontierStack's credential-free bridge to ~/.gemini/config/mcp_config.json, which the CLI, the app and the IDE share, and puts the FrontierStack skill in ~/.gemini/config/skills.
