How does microManager run Gemini CLI?
The built-in Gemini CLI profile runs:
gemini --acpin the workspace’s worktree and talks to it over the Agent Client Protocol. It uses the gemini on your login shell’s PATH, or the absolute path you set in Settings → Agents. The profile’s arguments are editable, so you can follow changes to Gemini CLI’s flags without waiting for a microManager update.
Who can still use Gemini CLI?
Google’s Gemini CLI README says that since 18 June 2026 it is for organizations with Gemini Code Assist Standard or Enterprise, or Code Assist for GitHub, on Google Cloud, plus older paid Gemini API and Vertex AI keys. Free Google accounts and Google AI Pro and Ultra moved to Antigravity CLI (agy).
Antigravity CLI speaks the Agent Client Protocol too. To use it, sign in once by running agy in a terminal, then in Settings → Agents choose Add ACP agent with the command agy and the argument acp.
What works with Gemini CLI?
Streamed replies, tool calls as cards, plans, permission requests, model choice when Gemini offers it and slash commands, plus microManager’s MCP tools. Worktrees, checkpoints, diff review and pull requests work as they do for every agent.
What do I need?
Gemini CLI installed and signed in with an account it still serves, so that gemini works in your terminal.
