pp-open-meteo
Every Open-Meteo endpoint family in one CLI — forecast, archive, marine, air quality, flood, climate, ensemble, seasonal, geocoding, elevation. Trigger phrases: `what's the weather in`, `forecast for`, `is it going to rain`, `marine forecast`, `air quality in`, `historical weather`, `climate normal`, `use open-meteo`, `run open-meteo`.
Why this skill is useful
Adds specific commands and workflows for weather data retrieval that the AI wouldn't reliably generate on its own.
What it needs
Requires open-meteo-pp-cli installed locally. About 8k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.
What this skill does
Open-Meteo — Printing Press CLI Prerequisites: Install the CLI This skill drives the open-meteo-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: open-meteo-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Use this CLI for any weather, climate, or air-quality question that does not require a paid commercial agreement. It covers forecasts (16 days, multiple models), historicals (ERA5 from 1940), marine waves, air quality with pollen, river flood discharge, CMIP6 climate projections, and ensemble runs. Reach for the novel commands (compare, normals, weather-mix, panel, is-good-for) when the user is asking a decision or anomaly question rather than a raw-data question. When Not to Use This CLI Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis. Unique Capabilities These capabilities aren't available in any other tool for this API. Local state that compounds forecast diff — See exactly what changed since the last forecast pull for this location — temperature deltas, new precipitation hours, weather-code shifts. …
