create-command Guide Skill

This skill allows Tars to create custom slash commands for Gemini CLI extensions.

Instructions

1. •Locate Extension: Navigate to the target extension directory (e.g., ~/.gemini/extensions/<name>).
2. •Create Directory: Create a commands directory if it doesn't exist, and a subdirectory for the command group (e.g., commands/utils).
   • •The directory structure determines the command name: commands/<group>/<name>.toml becomes /<group>:<name>.
3. •Create TOML File: Create a .toml file with the command definition.
4. •Define Content:
   • •prompt: The text sent to the LLM.
   • •{{args}}: Placeholder for user arguments.
   • •!{command}: Syntax to execute shell commands and inject output.

Template

# commands/utils/summarize.toml

prompt = """
Please summarize the content of the following file:

File Content:
!{cat {{args}}}
"""

Usage

After creating the file, restart the Gemini CLI (or re-link extension). Default commands are available immediately in commands/. The command above would be invoked as /utils:summarize path/to/file.
