Weather on the first ask

A guest walking up to Mu for the first time should be able to ask about the weather and get a useful forecast quickly. That’s what the recent refinement is about: making the first interaction with weather feel natural, not like a setup wizard. If you say “what’s the weather like?” and Mu has never seen you before, it should respond with something useful within a few seconds — not a blank stare or a technical error.

The trick is handling the two most common gaps: no location and no provider data. When Mu doesn’t know where you are, it can use your IP address to guess a city, but it says so plainly: “I’m using your approximate location based on your IP. If you want a different city, just tell me.” If the IP geolocation is too coarse or unavailable, Mu asks directly: “I don’t know where you are. Which city should I check?” No forced sign-up, no hidden permission prompts. The same honesty applies when the weather provider is down or returns no data. Mu says “I wasn’t able to get a forecast right now — the weather service didn’t return a result. Try again in a few minutes.” No fake confidence, no spinning wheel.

This matters for first-run usefulness because weather is one of the most common casual queries. A new user shouldn’t have to read documentation or configure a location before getting a simple answer. At the same time, Mu doesn’t pretend to know what it doesn’t. If the location is ambiguous or the data is stale, it says so. The goal is to be helpful quickly, but not at the cost of honesty. That trade-off is built into the design: get to a forecast fast, and when you can’t, say exactly why.
