Weather Skill

This skill demonstrates how to build an API integration skill using the SKILL.md format.

Overview

The weather skill fetches weather data from a public API and formats it for display. It shows patterns for:

• API integration with curl
• JSON parsing with jq
• Error handling
• Optional parameters with defaults

When to Use

Use this skill when you need to:

• Check current weather for a location
• Get weather forecasts
• Integrate weather data into workflows

Tools

current

Get current weather for a city.

This tool fetches real-time weather data including temperature, conditions, and humidity.

Parameters:

• city (required, string): City name (e.g., "London", "New York", "Tokyo")
• units (optional, string): Temperature units - "metric" for Celsius, "imperial" for Fahrenheit (default: metric)

Example:

# Basic usage
skill run weather:current city="London"

# With units
skill run weather:current city="Paris" units="metric"
skill run weather:current city="New York" units="imperial"

forecast

Get weather forecast for upcoming days.

Returns a multi-day weather forecast for the specified location.

Parameters:

• city (required, string): City name
• days (optional, integer): Number of days to forecast (1-5, default: 3)

Example:

# 3-day forecast (default)
skill run weather:forecast city="Berlin"

# 5-day forecast
skill run weather:forecast city="Tokyo" days=5

Implementation Notes

This skill uses:

• curl: For HTTP requests to weather API
• jq: For JSON parsing and formatting
• Environment variable: WEATHER_API_KEY for authentication

The API used is OpenWeatherMap (https://openweathermap.org/api). You'll need to configure your API key before using this skill.

Configuration

Set your OpenWeatherMap API key:

export WEATHER_API_KEY="your-api-key-here"

Or use skill config:

skill config weather
