Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wetter scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (wetter_core.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Wetter

Schnelle, schluesselfreie Wetterauskunft fuer den Alltag.

Zweck

Beantwortet „Wie wird das Wetter?"-Fragen ohne API-Key (Datenquelle: wttr.in). Liefert aktuelles Wetter (Temperatur, gefuehlt, Wind, Luftfeuchte, UV) plus eine kompakte 3-Tage-Vorschau. Userneutral: kein fester Standort im Code — der Ort kommt aus der Anfrage oder aus assist/prefs.json (wetter_default_location), die das LLM interaktiv mit dem Nutzer fuellt.

Trigger

Nutzereingabe Aktion
„Wetter fuer Potsdam?" / „Wie wird das Wetter in Hamburg?" wetter_core.py "<Ort>"
„Wetter morgen?" (ohne Ort) wetter_core.py --default (Ort aus prefs)
„Mein Standard-Wetterort ist Potsdam" wetter_core.py --set-default "Potsdam"
Koordinaten bekannt wetter_core.py <lat> <lon>

Workflow

1. Ort bestimmen: aus Anfrage; sonst prefs.json (wetter_default_location);
   sonst Nutzer interaktiv fragen + optional als Default speichern.
2. wetter_core.py abfragen (wttr.in, 2 Versuche, 30-min-Cache).
3. Lesbaren Wetter-Text + 3-Tage-Vorschau praesentieren.

CLI-Einstieg (wetter_core.py)

python wetter_core.py "Potsdam"          # Ort
python wetter_core.py 52.6789 13.5878   # Koordinaten
python wetter_core.py --default         # Ort aus prefs.json
python wetter_core.py --set-default "Potsdam"

Store (optional)

  • Kein Pflicht-Store. Optionaler Kurz-Cache assist/wetter/.cache.json (TTL 30 min, best-effort) — vermeidet wiederholte Netzabrufe.
  • Standortpraeferenz in assist/prefs.json (wetter_default_location).

Haltung

Wir nutzen wttr.in als schluesselfreie Default-Quelle, sind aber offen fuer andere Wetter-Backends (z.B. DWD/OpenWeather), falls der Nutzer das wuenscht.

Datenschutz

  • Nur der Ortsname/die Koordinaten gehen an wttr.in (noetig fuer die Abfrage).
  • Keine Telemetrie, kein Konto. Cache + Praeferenz bleiben lokal.

Verwandte Ressourcen

  • assist/AGENTS.md — Umbrella-Router
  • assist/reiseroute/ — nutzt Wetter ggf. fuer Reiseplanung (geplant)

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
