/echo

Name

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

Implementation logic:

if [ -n "$1" ]; then
  echo "Hello $1"
else
  echo "Hello world"
fi

Return Value

Claude agent text: "Hello world" (default) or "Hello $1" (when name is provided)

Examples

With a name argument:

```
