Repository Details
About
Google's official open-source terminal coding agent for Gemini. Brings Gemini's models and 1M-token context to the shell: read/edit files, run commands, ground answers with built-in Google Search, and automate via MCP servers and extensions. Free tier with a personal Google account offers generous request allowances. ReAct-style loop with checkpointing, custom slash commands, and GEMINI.md project context. Direct competitor to Claude Code and Codex CLI. Best for developers in the Google ecosystem and for high-context monorepo work. Limitation: tool reliability trails Claude Code on complex multi-file edits; quality depends on which Gemini tier is routed.
