A command that looks up a city's current time and weather, including temperature and the chance of precipitation during the next four hours.

Use it when someone gives a city name and wants its local time, current temperature, current precipitation, and near-term precipitation forecast.

It provides a repeatable way to gather a short city weather report instead of checking several details separately.

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.

Model	Per session	Once invoked
Fable 5	$0.00012	$0.00499
Opus 5	$0.00006	$0.00249
Sonnet 5	$0.00002	$0.00100
Haiku 4.5	$0.00001	$0.00050

Security

Grade A, and why

now 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 2d 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

City Weather Report

Get the current time, temperature (in both Fahrenheit and Celsius), and precipitation forecast for the next 4 hours for the specified city.

Instructions

Parse the city name from the arguments: $ARGUMENTS
Use the Open-Meteo Geocoding API to find the city coordinates:
```
curl -s "https://geocoding-api.open-meteo.com/v1/search?name=CITY_NAME&count=1&language=en&format=json"
```
Replace CITY_NAME with the URL-encoded city name.
Extract the latitude, longitude, and timezone from the response.

Use the Open-Meteo Weather API to fetch current weather and hourly forecast:

curl -s "https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&current=temperature_2m,precipitation&hourly=temperature_2m,precipitation_probability&timezone=TIMEZONE&forecast_hours=4"

Replace LAT, LON, and TIMEZONE with the values from step 3.

Format and present the results in a clear report:

City Weather Report for [City Name]
- Current Time: [formatted local time in the city's timezone]
- Temperature: [X]°F / [Y]°C
- Current Precipitation: [amount] mm

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.
