Description
Get current weather and forecasts (no API key required).
README (SKILL.md)
Weather
Two free services, no API keys needed.
wttr.in (primary)
Quick one-liner:
curl -s "wttr.in/London?format=3"
# Output: London: ⛅️ +8°C
Compact format:
curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h
Full forecast:
curl -s "wttr.in/London?T"
Format codes: %c condition · %t temp · %h humidity · %w wind · %l location · %m moon
Tips:
- URL-encode spaces:
wttr.in/New+York - Airport codes:
wttr.in/JFK - Units:
?m(metric)?u(USCS) - Today only:
?1· Current only:?0 - PNG:
curl -s "wttr.in/Berlin.png" -o /tmp/weather.png
Open-Meteo (fallback, JSON)
Free, no key, good for programmatic use:
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12¤t_weather=true"
Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.
Usage Guidance
This skill appears to do exactly what it says: issue curl requests to wttr.in and Open-Meteo and optionally save a PNG to /tmp. Before installing: ensure you are comfortable with an agent making outbound HTTP requests (these services will see the queried location and your agent's IP); confirm curl is available in your environment; and note minor metadata mismatches (the provided _meta.json has a different ownerId/slug/version than the registry metadata) — this is likely benign (packaging/versioning), but if provenance matters to you, verify the publisher/source before using the skill in automated scenarios.
Capability Analysis
Type: OpenClaw Skill
Name: gooduone-test-skill
Version: 1.1.0
The skill provides legitimate instructions for retrieving weather data using curl from well-known public services (wttr.in and open-meteo.com). No suspicious commands, data exfiltration, or prompt injection attempts were found in SKILL.md or _meta.json.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description (weather, no API key) match the instructions, which only use curl to query wttr.in and Open-Meteo. Required binary is only curl, which is appropriate. No credentials or config paths are requested.
Instruction Scope
Runtime instructions only run curl against wttr.in and api.open-meteo.com and optionally write a PNG to /tmp; that stays within the declared purpose. Note: queries will send the requested location (and the agent's network-level metadata such as IP) to those third-party services, so this exposes location/usage data to external servers.
Install Mechanism
No install spec (instruction-only), so nothing is downloaded or written to disk by an installer. This is the lowest-risk install posture.
Credentials
The skill declares no environment variables or credentials and the instructions do not reference any. No secrets are requested or required.
Persistence & Privilege
always is false and the skill does not request persistent system privileges or modify other skills. Autonomous invocation is allowed (platform default) but not combined with any broad access here.
How to Use
