Weather data loader (both history and forecast)

Fetch historical or forecast weather by location or coordinates via Open-Meteo. No API key needed.

Security Scan

The skill's code, instructions, and requirements are coherent with its stated purpose (fetching weather from Open‑Meteo); it requests no secrets and uses only reasonable dependencies and endpoints.

Purpose & Capability

Name/description match included scripts and utilities. The code calls Open‑Meteo forecast, archive, and geocoding endpoints, and implements aggregation/ET calculations that fit the stated functionality.

Instruction Scope

SKILL.md instructs running the provided scripts and documents CLI options. The runtime instructions only reference relevant inputs (location/lat/lon, days, kc) and produce CSV/JSON output; they do not ask for unrelated files, credentials, or broad system data.

Install Mechanism

No install spec; this is instruction+source distribution. requirements.txt lists only pandas and requests — proportional and expected. No downloads from untrusted URLs or archive extraction are present.

Credentials

The skill declares no required environment variables or credentials. Network access to Open‑Meteo endpoints is required; headers set a benign User‑Agent. No sensitive environment/config paths are accessed.

Persistence & Privilege

always is false, agent invocation is allowed (platform default). The skill does not modify other skills or system-wide configs and does not request elevated or persistent privileges.

Assessment

This skill appears internally consistent and implements exactly what it claims: fetching geocoded, historical, and forecast weather from Open‑Meteo and aggregating it. Before installing or running: (1) be aware the scripts perform outbound HTTP requests to Open‑Meteo (your IP and query strings are visible to that service); (2) install dependencies (pandas, requests) in a virtualenv or sandbox; (3) if you have strict privacy/network policies, run tests in an isolated environment first — tests perform live API calls; (4) review code if you require extra assurance (the code is short and readable); and (5) avoid enabling any skill-wide autonomous behaviors in high‑sensitivity environments without network controls (the skill needs network access to function). Overall, no secrets are requested and no unexplained or risky behavior was found.

Weather Data Fetcher

Fetch daily weather (historical and forecast) by location name or coordinates via Open-Meteo. No API key needed. Scripts: fetch_historical.py (historical), fetch_forecast.py (forecast).

When to invoke

Use this skill when the user asks for:

• Historical weather data for a location or coordinates
• Weather forecast for the next days
• Precipitation or evapotranspiration data for garden planning

Location vs coordinates

Provide either:

• Location: positional or --location / -l (e.g. "Oslo, Norway") — geocoded via Open-Meteo
• Coordinates: --lat and --lon (both required)

Days: --days N — history default 10 (max 30), forecast default 7 (max 15).

weather_fetch_historical

Run scripts/fetch_historical.py. Observed weather (Open-Meteo archive API). Default 10 days, max 30 (--days N).

python scripts/fetch_historical.py "Oslo, Norway"
python scripts/fetch_historical.py "Oslo, Norway" --days 20 --format json --kc 1.05
python scripts/fetch_historical.py --location "London, UK" --format csv
python scripts/fetch_historical.py --lat 59.91 --lon 10.75 --days 30

weather_fetch_forecast

Run scripts/fetch_forecast.py. Forecast weather. Default 7 days, max 15 (--days N).

python scripts/fetch_forecast.py "Oslo, Norway"
python scripts/fetch_forecast.py "Paris, France" --days 15 --format json --kc 1.0
python scripts/fetch_forecast.py --lat 59.91 --lon 10.75 --days 14 --format csv

Output columns

Column	Description
date	YYYY-MM-DD
temp	Mean daily temperature (°C)
precip	Total daily precipitation (mm)
et0_fao	FAO-56 reference evapotranspiration (mm/day), after kc
evaporation	Estimated crop evaporation (mm)
agg_precip	Cumulative precipitation
agg_evaporation	Cumulative evapotranspiration

kc (crop coefficient): multiplier applied to ET₀. Default 1.0.

Technical notes

• Historical: Open-Meteo archive API (observation/reanalysis); hourly → daily (temp = mean, precip/ET = sum).
• Forecast: Open-Meteo forecast API; same daily aggregation.
• Geocoding: location names resolved via Open-Meteo Geocoding API when not using --lat/--lon.

Troubleshooting

Symptom	Fix
Location not found	Try a simpler string (e.g. "Oslo") or use --lat and --lon
Provide either location or both --lat and --lon	Give a location (positional or --location) or both --lat and --lon
API failure	Check internet access; retry — Open-Meteo is free and usually reliable
