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

test-skill 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 3d 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 Information Fetcher

Fetches current weather data for any city using OpenWeatherMap API.

Dependencies

  • curl or wget for HTTP requests
  • OpenWeatherMap API key (free registration at openweathermap.org)
  • Environment variable: OPENWEATHER_API_KEY

Installation

  1. Sign up for API key at https://openweathermap.org/api
  2. Set environment variable: export OPENWEATHER_API_KEY=your_api_key
  3. Ensure curl is installed: which curl

Usage

  1. When user asks for weather information for a specific city
  2. Extract the city name from the request
  3. Make API call: curl "http://api.openweathermap.org/data/2.5/weather?q=CITY&appid=$OPENWEATHER_API_KEY&units=metric"
  4. Parse the JSON response and format for user
  5. Handle errors gracefully if city not found or API unavailable

Examples

# Example API call
curl "http://api.openweathermap.org/data/2.5/weather?q=London&appid=your_api_key&units=metric"

Expected response includes temperature, description, humidity, and pressure.

Error Handling

  • No API key: Prompt user to set OPENWEATHER_API_KEY environment variable
  • City not found: Return "City not found, please check spelling"
  • API down: Fallback to generic message "Weather service temporarily unavailable"
  • Network error: Retry once, then inform user of connection issue

Limitations

  • Requires internet connection
  • API has rate limits (1000 calls/day for free tier)
  • Only supports current weather (not forecasts)
  • City names must be in English

Troubleshooting

If you get "unauthorized" error:

  1. Verify API key is correct
  2. Check if key is activated (can take up to 10 minutes)
  3. Ensure environment variable is set properly

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.
