Command routing

Check $ARGUMENTS:

• reset → delete ~/.claude/skills/weather/preferences.md, confirm, stop
• anything else (including empty) → run the skill

Config

Use AskUserQuestion:

Q1 — "What city are you in?" (text input via Other)

• Options: suggest common cities as quick picks, plus Other for custom input

Q2 — "Temperature unit?"

• Celsius (default)
• Fahrenheit

Save to ~/.claude/skills/weather/preferences.md.

Reset

Delete ~/.claude/skills/weather/preferences.md and confirm: "Preferences cleared. Using defaults."

First-time detection

If no preferences file exists and no city argument was provided:

1. Use AskUserQuestion to ask: "Where are you located? (city name)"
2. After getting weather, offer to save the location

Steps

1. Determine location

• If $ARGUMENTS contains a city name (not help/config/reset) → use that city
• Else if preferences has a saved city → use that
• Else → ask via AskUserQuestion: "What city should I check the weather for?"

2. Geocode the city

Use WebFetch to call the Open-Meteo geocoding API:

https://geocoding-api.open-meteo.com/v1/search?name={city}&count=1&language=en&format=json

Extract latitude, longitude, and name (resolved city name) from the first result.

If no results found, tell the user and ask for a different city.

3. Fetch current weather

Use WebFetch to call the Open-Meteo forecast API:

https://api.open-meteo.com/v1/forecast?latitude={lat}&longitude={lon}&current=temperature_2m,relative_humidity_2m,apparent_temperature,weather_code,wind_speed_10m,wind_direction_10m&temperature_unit={celsius|fahrenheit}&wind_speed_unit=kmh&timezone=auto

4. Display weather

Show a fun, concise weather card:

{weather emoji} Weather in {City}

  Temperature:  {temp}°{C/F} (feels like {apparent}°)
  Conditions:   {description from weather code}
  Humidity:     {humidity}%
  Wind:         {speed} km/h {direction}

  {fun one-liner comment about the weather}

Weather code mapping (WMO codes):

• 0: Clear sky
• 1-3: Partly cloudy
• 45, 48: Foggy
• 51-55: Drizzle
• 61-65: Rain
• 66-67: Freezing rain
• 71-77: Snow
• 80-82: Rain showers
• 85-86: Snow showers
• 95-99: Thunderstorm

Emoji mapping:

• Clear → sun
• Cloudy → cloud
• Rain/Drizzle → rain
• Snow → snowflake
• Thunderstorm → lightning
• Fog → fog

5. Offer to save (first-time only)

If no preferences existed and no city argument was given, ask:

Save {City} as your default location?

If yes, write preferences file.

Principles

• Always live data — never cache or guess weather; always fetch fresh from the API.
• Fun and concise — keep it light. One screen, one glance. Add a witty comment about the conditions.
• Fail gracefully — if the API is down or city not found, say so clearly and suggest alternatives.
• Respect saved preferences — once configured, just show the weather with zero friction.
