Weather

Two free services, no API keys needed.

Important Guidelines

Before using this skill:

1. Extract location: If the user mentions a city/location (e.g., "What's the weather in Beijing?"), extract the location and query directly.
2. Ask if missing: If the user says "check weather" without specifying a location, you MUST ask: "Which city would you like to check the weather for?"
3. Do NOT use example cities: The examples below show placeholder cities for demonstration only. Never query any city unless the user explicitly requests it.

wttr.in (primary)

Quick one-liner (replace {location} with the user-specified city):

curl -s "wttr.in/{location}?format=3"
# Example: curl -s "wttr.in/Beijing?format=3"
# Output: Beijing: ⛅️ +8°C

Compact format (replace {location} with user-specified city):

curl -s "wttr.in/{location}?format=%l:+%c+%t+%h+%w"
# Example: curl -s "wttr.in/Shanghai?format=%l:+%c+%t+%h+%w"
# Output: Shanghai: ⛅️ +15°C 65% ↙8km/h

Full forecast:

curl -s "wttr.in/{location}?T"

Format codes: %c condition · %t temp · %h humidity · %w wind · %l location · %m moon

Tips:

• URL-encode spaces: wttr.in/New+York or wttr.in/New%20York
• Airport codes: wttr.in/JFK, wttr.in/PEK
• Units: ?m (metric) ?u (USCS)
• Today only: ?1 · Current only: ?0
• PNG: curl -s "wttr.in/{location}.png" -o /tmp/weather.png

Open-Meteo (fallback, JSON)

Free, no key, good for programmatic use. First get coordinates for the user-specified city, then query:

# Example for Beijing (latitude=39.9&longitude=116.4)
curl -s "https://api.open-meteo.com/v1/forecast?latitude=39.9&longitude=116.4&current_weather=true"

Returns JSON with temp, windspeed, weathercode.
