   • wttr (default): wttr first, Open-Meteo fallback
   • open-meteo: Open-Meteo first, wttr fallback
4. Pass user location text to location.

Tool Parameters

• location (required): city, region, airport code, or place name. Supports English, Chinese, Japanese, and Korean.
• language (optional): output language. auto (default) detects from input — Hangul → Korean, hiragana/katakana → Japanese, CJK → Simplified Chinese, otherwise English. Can be set explicitly to en-US, zh-Hans, zh-Hant, ja, or ko.

• source: actual provider used (wttr or open-meteo).
• source_display: UI-ready source label (Source: wttr.in. or Source: Open-Meteo.).
• language: resolved output language (en-US, zh-Hans, zh-Hant, ja, or ko).
• location: resolved location name from provider.
• condition: weather condition text (translated when CJK/Japanese output).
• temperature: current temperature in selected units.
• temperature_unit: °C or °F.
• feels_like: feels-like temperature.
• humidity: relative humidity percentage.
• wind_speed: wind speed in selected units.
• wind_speed_unit: km/h or mph.
• summary: concise weather sentence without inline source text (localized).
• open_meteo_compliance_notice: Open-Meteo attribution plus modification declaration (only when source is Open-Meteo).
• rate_limit_notice: fallback notice (only when Open-Meteo fails, including HTTP 429, and fallback is triggered).

Language Support

Language	Detection	Weather Translation	Geocoding
English (en-US)	Default	Passthrough	Standard
Simplified Chinese (zh-Hans)	CJK characters	Full (160+ terms)	zh + en
Traditional Chinese (zh-Hant)	Explicit only	Full (zh-Hans + override)	zh + en
Japanese (ja)	Hiragana/Katakana	Full (160+ terms)	ja + en
Korean (ko)	Hangul	Full (160+ terms)	ko + en

Auto-detection rules:

• Hangul Syllables (U+AC00–U+D7AF) → ko
• Hiragana (U+3040–U+309F) or Katakana (U+30A0–U+30FF) → ja
• CJK characters → zh-Hans
• Otherwise → en-US

Compliance Notes

• For CC BY scenarios, render open_meteo_compliance_notice in a visible area when source=open-meteo.
• Do not silently drop open_meteo_compliance_notice when Open-Meteo is the actual source.
• source and source_display are useful for traceability and UI, but they do not replace open_meteo_compliance_notice.
• rate_limit_notice is returned only when Open-Meteo fails and fallback is activated.
