Antigravity CLI

Gemini CLI Is Being Retired

Google replaced Gemini CLI with Antigravity CLI (agy) and stopped serving individual-tier accounts on June 18, 2026. Antigravity CLI reuses your existing ~/.gemini home, honors both GEMINI.md and AGENTS.md, and can import installed Gemini CLI extensions as Antigravity plugins — including Nowledge Mem.

One-Minute Setup

1. Install the Nowledge Mem extension for Gemini CLI (see the Gemini CLI guide).
2. Install Antigravity CLI: curl -fsSL https://antigravity.google/cli/install.sh | bash
3. Run agy plugin import gemini to convert the extension into an Antigravity plugin.
4. Run nmem status once, then open a new agy session.

MCP Configuration

Antigravity CLI keeps MCP servers in .agents/mcp_config.json. Generate the Mem block with nmem config mcp show --host gemini-cli and place it there; remote server definitions use serverUrl instead of url.

What You Get

• The same Context Bundle / Working Memory, routed recall, distillation, and handoff surfaces inside Antigravity CLI
• Bundled local MCP tools for retrieval and memory writes
• Session capture through the shared ~/.gemini history: nmem t save --from gemini-cli
• Older sessions backfilled with nmem t sync --from gemini-cli --all-projects
• Clean local and remote auth through nmem

Known Boundaries

• agy plugin import gemini is Google's official migration channel and the supported way to run the Nowledge Mem extension under Antigravity today.
• Session capture reads the shared ~/.gemini history through the Gemini CLI connector; if Google moves Antigravity session storage, re-verify with nmem t sync --from gemini-cli --limit 5 after upgrading agy.
