Using Gemini CLI

Gemini CLI extends Claude's capabilities with multimodal and web access features. Use it for tasks Claude cannot do natively: analyzing images, analyzing videos, accessing YouTube content, fetching web pages, and searching the web with Google.

Base Command Syntax

bash

gemini --allowed-mcp-server-names "" [other-flags] "Your prompt here"

Always use --allowed-mcp-server-names "" to disable MCP servers for faster startup.

Controlling Detail Level

Control the detail level of Gemini's responses through your prompt wording:

•For comprehensive analysis: Add "in detail" to your prompt
•For quick summaries: Use "briefly" in your prompt

Note: Each use case may have specific wording requirements. Check the reference file for use-case-specific guidance on prompt wording.
