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-fetcher scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Weather Fetcher Skill

This skill provides instructions for fetching current weather data.

Task

Fetch the current temperature for Dubai, UAE in the requested unit (Celsius or Fahrenheit).

Instructions

  1. Fetch Weather Data: Use the WebFetch tool to get current weather data for Dubai from the Open-Meteo API.

    For Celsius:

    • URL: https://api.open-meteo.com/v1/forecast?latitude=25.2048&longitude=55.2708&current=temperature_2m&temperature_unit=celsius

    For Fahrenheit:

    • URL: https://api.open-meteo.com/v1/forecast?latitude=25.2048&longitude=55.2708&current=temperature_2m&temperature_unit=fahrenheit
  2. Extract Temperature: From the JSON response, extract the current temperature:

    • Field: current.temperature_2m
    • Unit label is in: current_units.temperature_2m
  3. Return Result: Return the temperature value and unit clearly.

Expected Output

After completing this skill's instructions:

Current Dubai Temperature: [X]°[C/F]
Unit: [Celsius/Fahrenheit]

Notes

  • Only fetch the temperature, do not perform any transformations or write any files
  • Open-Meteo is free, requires no API key, and uses coordinate-based lookups for reliability
  • Dubai coordinates: latitude 25.2048, longitude 55.2708
  • Return the numeric temperature value and unit clearly
  • Support both Celsius and Fahrenheit based on the caller's request
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.
