Weather (Deutsch)

Fast, key-free weather information for everyday use.

Übersicht & Zweck

Answers "What will the weather be like?" questions without an API key (data source: wttr.in). Delivers current weather (temperature, feels-like, wind, humidity, UV) plus a compact 3-day forecast. User-neutral: no fixed location in the code — the location comes from the request or from assist/prefs.json (wetter_default_location), which the LLM fills in interactively with the user.

Triggers

User input	Action
"Weather for Potsdam?" / "What will the weather be like in Hamburg?"	`wetter_core.py "<location>"`
"Weather tomorrow?" (without location)	`wetter_core.py --default` (location from prefs)
"My default weather location is Potsdam"	`wetter_core.py --set-default "Potsdam"`
Coordinates known	`wetter_core.py <lat> <lon>`

Workflow & Vorgehen

1. Determine location: from request; else prefs.json (wetter_default_location);
   else ask user interactively + optionally save as default.
2. Query wetter_core.py (wttr.in, 2 attempts, 30-min cache).
3. Present readable weather text + 3-day forecast.

CLI Entry Point (wetter_core.py)

python wetter_core.py "Potsdam"          # location
python wetter_core.py 52.6789 13.5878   # coordinates
python wetter_core.py --default         # location from prefs.json
python wetter_core.py --set-default "Potsdam"

Store (optional)

No mandatory store. Optional short cache assist/wetter/.cache.json (TTL 30 min, best-effort) — avoids repeated network calls.
Location preference in assist/prefs.json (wetter_default_location).

Attitude

We use wttr.in as the key-free default source, but are open to other weather backends (e.g. DWD/OpenWeather) if the user prefers them.

Privacy

Only the location name/coordinates go to wttr.in (required for the query).
No telemetry, no account. Cache + preference stay local.
