weather-now

Trigger

Use this skill when the user asks for current weather, short-range forecast, rain probability, or temperature for a named place. Examples:

• "今天上海下雨吗"
• "北京气温现在多少"
• "weekend weather in Tokyo"

Do NOT use this for historical climate, severe-weather alerts, marine / aviation weather, or hyper-local microclimate questions — those need specialised sources.

Inputs

• location: city, region or airport code. If the user did not name a

place, ask once. Do not invent a default.

• mode: one of now (default), today, forecast (3-day),

rain (precipitation focus).

Steps

1. URL-encode the location (replace spaces with +).
2. Call read_url with one of:

• now / rain: https://wttr.in/<loc>?format=3
• today: https://wttr.in/<loc>?0
• forecast: https://wttr.in/<loc>?format=v2

1. Trim the response to the relevant lines. wttr.in returns ASCII art

for full forecasts — keep only the summary line + per-day temps.

1. Reply in one short message. Use Celsius and the user's language

(Chinese or English) inferred from the question.

1. End with the location and the time-of-check (Beijing time) so

the user can tell when the data was fetched.

Verification

• Output must contain the resolved location string.
• Numeric temperature / precipitation values come from the response, not

invented.

• For rain checks, state probability or "无降水"; do not guess.
• If read_url returns 5xx or empty, say so plainly and offer to retry.

Failure Signals

• Location ambiguous (e.g. "我家附近") and not recoverable from memory.
• wttr.in unreachable or returns rate-limit message.
• Reply contains ASCII art / tables that don't render in IM.
• User asked for severe-weather alerts or aviation weather — refuse

and recommend an official source.
