Gemini. Is Google’s open-source agentic coding agent for the terminal, ReAct loop, built-in tools (files, shell, search), MCP servers, and large-context Gemini models.

Summary

Gemini CLI (google-gemini/gemini-cli) runs an agent loop in your repo: reason, call tools, checkpoint conversations, and load project context via GEMINI.md. It shares quota with Gemini Code Assist agent mode on free and paid Google tiers.

Use for interactive coding, refactors, and skill-driven workflows when Gemini models or Google Cloud billing are the constraint. It is a repo-bounded AI Agent; not an omnichannel personal bot (OpenClaw, Hermes are hold). For scheduled automation, prefer deterministic scripts and Dagu with LLM steps only where reasoning is required.

Compare Claude Code (Anthropic) and Codex (OpenAI) for the same agent-loop-in-repo pattern.
