hello-world-echo

Name

odh-ai-helpers:hello-world-echo

Synopsis

/hello-world:echo [name]

Description

The hello-world:echo command prints a greeting message to the console. By default, it prints "Hello world", but when provided with a name argument hello-world:echo $1, it prints "Hello ${1}". This command serves as a basic example of a Claude Code plugin implementation, demonstrating the minimal structure required for a functional plugin command.

It provides a reference implementation for plugin developers. It demonstrates:

• Basic command structure
• Shell command execution within a plugin
• Handling arguments
• Minimal configuration requirements

The spec sections is inspired by https://man7.org/linux/man-pages/man7/man-pages.7.html#top_of_page

Implementation

• The command executes a simple bash echo statement
• Accepts an optional name argument ($1)
• If $1 is provided, outputs "Hello $1"
• If no argument is provided, outputs "Hello world"
• Output is sent directly to standard output
• The command is stateless and has no side effects

Examples

1. Basic usage (no arguments):

   /hello-world:echo
   

   Output:

   Hello world
   

2. With a name argument:

   /hello-world:echo Alice
   

   Output:

   Hello Alice
   

3. With multiple words as name:

   /hello-world:echo "John Doe"
   

   Output:

   Hello John Doe
