open-meteo-weather-forecast is a skill for Claude Code, Codex from runxhq/runx. It costs 31 tokens per session (748 once invoked), scanned A, original, Apache-2.0.

A worldwide weather and air-quality service using Open-Meteo, a public forecast provider that covers places around the globe. It first resolves a place name, then retrieves conditions for its coordinates.

In plain words
What is it for?
It helps planning workflows look up a city or place and obtain its current weather, daily forecast, and air-quality data.
Why use it?
It supplies forecast evidence without an API key and records the place, provider response, and request details.

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

open-meteo-weather-forecast 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 8d 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.

Open-Meteo Weather Forecast

Fetch global place, forecast, and air-quality evidence through runx's governed HTTP front. The skill never performs an ad-hoc fetch. Each stage is a bounded, read-only HTTP runner whose endpoint, inputs, status, authority scope, and output packet are recorded in the sealed receipt. Open-Meteo requires no API key and covers the whole globe, so this is the worldwide counterpart to the US-only nws-weather-forecast provider.

Procedure

  1. Run locate with a city or place name.
  2. Select the intended result and preserve its latitude, longitude, timezone, and country as a typed provider-evidence packet.
  3. Run the default forecast runner with the selected coordinates.
  4. Require a 2xx response and preserve the provider URL, timezone, generation time, current conditions, daily forecast, and receipt references.
  5. Treat the result as context only. Any notification, scheduling change, or operational mutation requires a separate skill and authority gate.

Inputs

  • name (locate, required): city or place to resolve.
  • count (locate, optional): maximum candidate results, default 5.
  • latitude (forecast, required): decimal latitude.
  • longitude (forecast, required): decimal longitude.
  • forecast_days (forecast, optional): days requested, default 3.

Output packets

Two runners are exposed. The default main runner runs locate then forecast. The air_quality runner runs locate then air_quality. Each graph step produces a typed sealed packet:

  • locate produces Open-Meteo geocoding provider evidence.
  • forecast produces Open-Meteo forecast provider evidence.
  • air_quality produces Open-Meteo air-quality provider evidence (PM2.5, PM10, carbon monoxide, nitrogen dioxide, sulphur dioxide, ozone, and the European and US air-quality indices).

Preserve provider metadata and receipt references when passing either packet to another skill. Do not convert provider evidence into high-stakes advice.

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.
