Weather Skill

Fast, reliable current weather via wttr.in — one curl call, no API key, no browser required, works in containers and VMs where Chrome/Chromium is unavailable.

When to Use

User asks for current weather, temperature, conditions, wind, humidity for any city
User asks for a weather forecast
Browser-based tools fail (headless Chrome not available)
Speed matters — wttr.in responds in <1s

DO NOT use `delegate_task` for simple weather lookups

delegate_task with toolsets=["web"] for a simple weather query timed out at 216 seconds in practice. Use curl wttr.in directly instead — it's the right tool for this class of task.

Quick One-Liner (current conditions)

curl -s "https://wttr.in/<CITY>,<COUNTRY_CODE>?format=%l:+%C,+%t,+vítr+%w,+vlhkost+%h"

Format tokens

Token	Meaning
`%l`	Location name
`%C`	Weather condition (text)
`%t`	Temperature
`%w`	Wind speed + direction arrow
`%h`	Humidity
`%p`	Precipitation (mm)
`%P`	Atmospheric pressure (hPa)
`%S`	Sunrise time
`%s`	Sunset time
`%m`	Moon phase

Examples

# Current weather — Czech city
curl -s "https://wttr.in/Zlin,CZ?format=%l:+%C,+%t,+vítr+%w,+vlhkost+%h"
# → zlin,cz: Partly cloudy, +14°C, vítr ↓7km/h, vlhkost 82%

# Specific small village with district (disambiguate with full name)
curl -s "https://wttr.in/Hrusky,Breclav,CZ?format=%l:+%C,+%t,+vítr+%w,+vlhkost+%h"

# Simple 3-field format (city + condition + temp)
curl -s "https://wttr.in/Prague?format=3"
# → Prague: ⛅  +17°C

# Full ASCII forecast block (3 days)
curl -s "https://wttr.in/London?lang=en"

Multi-Day Forecast (JSON)

curl -s "https://wttr.in/<CITY>.json" | python3 -c "
import json,sys
d = json.load(sys.stdin)
cc = d['current_condition'][0]
print(f\"Temp: {cc['temp_C']}°C, Feels like: {cc['FeelsLikeC']}°C\")
print(f\"Condition: {cc['weatherDesc'][0]['value']}\")
print(f\"Wind: {cc['windspeedKmph']} km/h {cc['winddir16Point']}\")
print(f\"Humidity: {cc['humidity']}%\")
"

Language Support

Append &lang=<code> for localized condition strings:

curl -s "https://wttr.in/Praha?format=%C+%t&lang=cs"   # Czech
curl -s "https://wttr.in/Berlin?format=%C+%t&lang=de"  # German
curl -s "https://wttr.in/Paris?format=%C+%t&lang=fr"   # French

Pitfalls

Ambiguous city names: add country code (CZ, DE, US) or region (Hrusky,Breclav,CZ) to disambiguate small villages
UTF-8 arrows in wind: the ↓↑→← direction arrows render fine in Discord/Telegram
Rate limiting: wttr.in is a free public service — don't hammer it in loops; for batch queries add sleep 1 between calls
Container environments: Chrome/Chromium browser tools often fail with sandbox errors in Docker/VMs; curl wttr.in always works

Presenting Results in Chat

Format with emojis for readability in Discord/Telegram:

🌤️ **Počasí v Zlíně**
- 🌥️ Podmínky: Částečně oblačno
- 🌡️ Teplota: +14 °C
- 💨 Vítr: 7 km/h (severní)
- 💧 Vlhkost: 82 %

Map condition keywords to emojis: - Clear / sunny → ☀️ - Partly cloudy → 🌤️ - Cloudy / overcast → ☁️ - Rain / drizzle → 🌧️ - Snow → ❄️ - Thunderstorm → ⛈️ - Fog / mist → 🌫️
