Get Weather Skill

When to Use

Use this skill whenever the user asks about:

• Current weather conditions in a city or location
• Temperature (today, this week)
• Forecast (hourly, daily, weekly)
• Rain, snow, wind, humidity, or UV index
• Phrases like "what's the weather in X", "is it raining in X", "will it snow"

How to Fetch Weather

Use wttr.in — no API key required.

PowerShell (Windows)

# Current weather (plain text, one-line)
(Invoke-WebRequest -Uri "https://wttr.in/Tokyo?format=3" -UseBasicParsing).Content

# Full forecast (3 days)
(Invoke-WebRequest -Uri "https://wttr.in/Tokyo?format=4" -UseBasicParsing).Content

# JSON for programmatic use
$weather = Invoke-WebRequest -Uri "https://wttr.in/Tokyo?format=j1" -UseBasicParsing | ConvertFrom-Json
$weather.current_condition[0]

Shell / curl (macOS/Linux)

# One-line summary
curl "https://wttr.in/Tokyo?format=3"

# Full forecast
curl "https://wttr.in/Tokyo"

# JSON
curl "https://wttr.in/Tokyo?format=j1" | jq '.current_condition[0]'

Python

import urllib.request, json

city = "Tokyo"
url = f"https://wttr.in/{city}?format=j1"
with urllib.request.urlopen(url) as r:
    data = json.loads(r.read())

current = data["current_condition"][0]
print(f"Temp: {current['temp_C']}°C / {current['temp_F']}°F")
print(f"Feels like: {current['FeelsLikeC']}°C")
print(f"Humidity: {current['humidity']}%")
print(f"Wind: {current['windspeedKmph']} km/h {current['winddir16Point']}")
print(f"Description: {current['weatherDesc'][0]['value']}")

Format Codes (wttr.in)

Format	Description
?format=3	City: ⛅ +18°C one-liner
?format=4	Multi-line with forecast
?format=j1	Full JSON response
?format=%t	Temperature only
?format=%h	Humidity only
?format=%w	Wind only
?format=%C	Condition description

Steps

1. Extract the city/location from the user's request
2. Run the appropriate command for the current OS
3. Parse and present the result in a readable format
4. If the city name has spaces, replace them with + (e.g., New+York)
