Outputs: What will the skill return or display after execution?

Create a blueprint or pseudo-code to streamline your implementation.

3.2 Skill Implementation

In the /skills directory, create a new file named after your skill (e.g., my_new_skill.py for Python). Here’s an example structure for a Python skill:

class MyNewSkill:
    def __init__(self, data):
        self.data = data

    def execute(self):
        try:
            return f"Processed input: {self.data}"
        except Exception as e:
            return f"An error occurred: {str(e)}"

Comment clearly throughout your code to improve readability and maintainability.

Step 4: Testing Your Skill

4.1 Writing and Organizing Unit Tests

Tests ensure your skill operates correctly and remains reliable even after changes. In the /tests folder, create a test file corresponding to your skill.

Example in /tests/test_my_new_skill.py:

import unittest
from skills.my_new_skill import MyNewSkill

class TestMyNewSkill(unittest.TestCase):
    
    def test_execute_valid(self):
        skill = MyNewSkill("test")
        self.assertEqual(skill.execute(), "Processed input: test")
    
    def test_execute_error(self):
        skill = MyNewSkill(None)
        self.assertIn("An error occurred", skill.execute())

if __name__ == "__main__":
    unittest.main()

4.2 Run Tests

Use appropriate commands to run your tests:

For Python:

python -m unittest discover

For JavaScript:

npm test

Ensure all tests pass before proceeding.

Step 5: Documenting Your Skill

Documentation is critical so others can understand and use your work effectively. Add or update relevant files in the /docs directory, describing:

The purpose and functionality of your skill.

New Section: Advanced Skill Implementation Examples

Adding External APIs to Your Skill

One way to create a highly functional skill is by integrating an external API. For instance, creating a weather-fetching skill:

import requests

class WeatherSkill:
    def __init__(self, location, api_key):
        self.location = location
        self.api_key = api_key

    def fetch_weather(self):
        try:
            url = f"http://api.openweathermap.org/data/2.5/weather?q={self.location}&appid={self.api_key}"
            response = requests.get(url)
            response.raise_for_status()
            data = response.json()
            return f"Current weather in {self.location}: {data['weather'][0]['description']}, temperature: {data['main']['temp']}K"
        except Exception as e:
            return f"An error occurred: {str(e)}"

This skill demonstrates how you can use APIs (like OpenWeather) to augment functionality. Always include proper error handling to ensure robust operations.

### Creating Skills with Multiple Functionalities

Skills can also include several related functions. For instance, a calculator skill:

```python
class CalculatorSkill:
    def add(self, a, b):
        return a + b

    def subtract(self, a, b):
        return a - b

    def multiply(self, a, b):
        return a * b

    def divide(self, a, b):
        if b == 0:
            return "Division by zero is undefined"
        return a / b
These examples showcase that skills can be tailored for one specific task or for a group of closely related tasks.
