How do I create custom commands for the Gemini CLI?▼

To create custom commands for the Gemini CLI, you define command syntax and arguments using TOML configuration files and map them to specific prompts within an extension-based structure.

What are extension-based commands in the Gemini CLI?▼

Extension-based commands in the Gemini CLI are custom slash commands integrated within Gemini extensions, allowing you to extend CLI functionality by mapping defined TOML configurations to actionable prompts.

How do I define command arguments using TOML for my CLI tool?▼

You define command arguments using TOML by specifying the argument syntax within a configuration file, which the Gemini CLI then parses to handle inputs like file paths for your custom commands.
