weather is a skill for Claude Code, Codex from Threat-Vector-Security/guardian-agent. It costs 0 tokens per session (339 once invoked), scanned A, a copy of weather, Apache-2.0.

A workflow for getting current weather from free web services such as wttr.in and Open-Meteo. It supports short current conditions, forecasts, and machine-readable weather data.

In plain words
What is it for?
Checking current conditions, retrieving forecasts, querying weather in JSON, and getting details such as temperature, humidity, wind, and moon information.

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 7d 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.

Files

What ships with it

2 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.
