+
+## 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:
+```bash
+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
+
+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
+   ```
+
+## Arguments:
+- $1: The name to be printed "Hello ${1}"
