Overview

Expert skill for defining custom slash commands in the Gemini CLI. Unlike Claude Code's markdown-based commands, Gemini uses TOML configuration or Extension-based commands.

When to Use This Skill

Keywords: gemini commands, custom slash commands, .toml commands, command arguments, command alias

Use this skill when:

  • Creating custom commands in commands.toml (or similar)
  • creating extension-based commands (<extension>/commands/*.toml)
  • Defining command arguments and defaults
  • Mapping commands to complex prompts

Command Structure (TOML)

Gemini commands are typically defined in TOML files within extensions or configuration.

[command-name]
description = "Description"
prompt = "The actual prompt to send..."

(Note: Verify exact syntax via gemini-cli-docs as specific implementation details vary by version)
