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
- URL-encode the location (replace spaces with
+).
- 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
- Trim the response to the relevant lines. wttr.in returns ASCII art
for full forecasts — keep only the summary line + per-day temps.
- Reply in one short message. Use Celsius and the user's language
(Chinese or English) inferred from the question.
- 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.
