Python Example Skill

A comprehensive example demonstrating Python SDK features including decorators, configuration, multiple tools, and proper error handling.

When to Use

• Learning how to build skills with the Python SDK
• Testing the skill-engine runtime with Python-based skills
• As a template for creating new Python skills

Tools Provided

greet

Greet someone with a personalized message. Supports formal and informal greeting styles.

Usage:

skill run python-example:greet --name "Alice"
skill run python-example:greet --name "Alice" --formal true

Parameters:

• name (optional): The name of the person to greet (default: "World")

Good day, CEO. How may I assist you?

echo

Echo back a message with optional transformations like uppercase or reverse.

Usage:

skill run python-example:echo --message "Hello World"
skill run python-example:echo --message "hello" --uppercase true
skill run python-example:echo --message "stressed" --reverse true

Parameters:

• message (required): The message to echo
• uppercase (optional): Convert message to uppercase (default: false)
• reverse (optional): Reverse the message (default: false)

Example:

$ skill run python-example:echo --message "stressed" --reverse true
desserts

calculate

Perform basic arithmetic operations on two numbers.

Usage:

skill run python-example:calculate --a 10 --b 5 --operation add
skill run python-example:calculate --a 100 --b 7 --operation divide

Parameters:

• a (required): First number
• b (required): Second number
• operation (optional): Operation to perform - add, subtract, multiply, divide (default: "add")

Example:

$ skill run python-example:calculate --a 15 --b 3 --operation multiply
15 multiply 3 = 45

process_list

Process a JSON array of numbers and return statistics including count, sum, min, max, and average.

Usage:

skill run python-example:process_list --items '[1, 2, 3, 4, 5]'

Parameters:

• items (required): JSON array of numbers to process

Example:

$ skill run python-example:process_list --items '[10, 20, 30, 40, 50]'
Processed 5 items
{
  "count": 5,
  "sum": 150,
  "min": 10,
  "max": 50,
  "average": 30.0
}

status

Get current skill configuration and status including available tools.

Usage:

skill run python-example:status

Example:

$ skill run python-example:status
{
  "skill_name": "python-example",
  "version": "1.0.0",
  "config": {
    "greeting_prefix": "Hello",
    "max_items": 100
  },
  "tools_available": ["greet", "echo", "calculate", "process_list", "status"]
}

Configuration
