Weather Now

Q: How do I know the Weather Now output is good?

The skill verifies itself against its own quality checks: The first line answers the actual question (rain timing, not temperature, if rain was asked); Units match the user's locale or stated preference; The source and its timestamp are quoted; The rerunnable curl appears.

Get current weather and forecasts with zero API keys — wttr.in one-liners for humans, Open-Meteo JSON for data, with the exact curl commands and format codes. Use when asked what's the weather, will it rain today, forecast for a city, or get me weather data for a location. Produces the live conditions or forecast pulled via curl, interpreted plainly, with the source timestamp and the command used shown so the user can rerun it.

What to give it

▸Location — city name, airport code (wttr.in takes IATA), lat/lon, or "here" (ask rather than guess the user's location)

▸What they actually want — right-now vs. today vs. multi-day; "will it rain" wants precipitation timing, not a temperature

▸Units — metric/imperial if ambiguous from the location

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The first line answers the actual question (rain timing, not temperature, if rain was asked)

✓Units match the user's locale or stated preference

✓The source and its timestamp are quoted

✓The rerunnable curl appears

✓Fallback engaged silently on primary failure, and the answer names which source spoke

⚠️ What it refuses to do

Do not answer from memory — no network means no weather; say so and hand over the command

Do not dump raw JSON as the answer — interpret first, data second

Do not guess the user's location — ask, or use the location they named

Do not present a rate-limited wttr.in error page as weather

Do not oversell precision — hour-level precipitation timing is a forecast, and the wording should sound like one
