What is Gemini CLI

Gemini CLI is Google's agentic coding tool for the terminal. It leverages Gemini models with up to 1M tokens of context, built-in Google Search grounding, and can read/edit files, run shell commands, and fetch web content.

When to delegate to Gemini CLI

Use Gemini CLI when you need to:
