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

weather 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 9d ago.

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.

What it actually says

Weather

Two free services, no API keys needed.

wttr.in (primary)

Quick one-liner:

curl -s "wttr.in/London?format=3"
# Output: London: ⛅️ +8°C

Compact format:

curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h

Full forecast:

curl -s "wttr.in/London?T"

Format codes: %c condition · %t temp · %h humidity · %w wind · %l location · %m moon

Tips:

  • URL-encode spaces: wttr.in/New+York
  • Airport codes: wttr.in/JFK
  • Units: ?m (metric) ?u (USCS)
  • Today only: ?1 · Current only: ?0
  • PNG: curl -s "wttr.in/Berlin.png" -o /tmp/weather.png

Open-Meteo (fallback, JSON)

Free, no key, good for programmatic use:

curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true"

Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.

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.
