Weather Forecast

When to use

Call get_weather when the user asks about conditions or a forecast. Typical phrasings:

• "what's the weather in Lisbon next week"
• "will it rain on the 12th"
• "how cold will it be in Tokyo in December"
• "should I pack a coat for Madrid"

Do NOT call for general climate questions ("what's Lisbon usually like in spring") — answer in prose for those.

How to use

1. Resolve the date. If the user says "next week" or "the 12th", call compute_relative_date to get a YYYY-MM-DD. If they ask for "today", call get_current_date.
2. Call get_weather({ city, date }). The tool returns { tempC, tempF, condition, summary, source }.
3. Reply in one short sentence with the user-facing values. Mention source only if it's the mock (the user should know they're seeing demo data, not a real forecast).

Output narration

Examples of good replies:

• "Lisbon on 2026-05-20: 22°C, partly cloudy."
• "Tokyo on 2026-12-15: -2°C, light snow expected (mock data — set OPENWEATHER_API_KEY for live)."

Anti-patterns

• Do NOT call get_weather repeatedly for adjacent days; one call per city/day is enough for a single user question.
• Do NOT recommend specific clothing items here; that's the packing skill's job. Just report the conditions.
• Do NOT hide the source: "mock" flag from the user.
