# 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.
