/install denfly-skill
功能描述
Get current weather and forecasts (no API key required).
使用说明 (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.
安全使用建议
This skill is coherent and limited in scope: it simply runs curl against public weather endpoints (wttr.in and Open-Meteo). Before installing, confirm you are comfortable that queries and your IP address will be visible to those services (public endpoints typically log requests). Note the internal _meta.json ownerId/slug differ from the registry header — this looks like a packaging/metadata mismatch; if provenance matters to you, verify the publisher or prefer a skill whose metadata matches the registry. Also ensure curl is present on the host and be aware the example can write a PNG to /tmp (it won’t access your secrets or other files).
功能分析
Type: OpenClaw Skill
Name: denfly-skill
Version: 1.0.0
The skill provides legitimate instructions for retrieving weather data from public APIs (wttr.in and open-meteo.com) using standard curl commands. No malicious code, data exfiltration, or prompt injection attempts were identified in SKILL.md or _meta.json.
能力评估
Purpose & Capability
The name/description (weather, no API key) align with the runtime instructions (curl calls to wttr.in and api.open-meteo). Required runtime binary is only curl, which is appropriate. Minor inconsistency: registry metadata at the top lists ownerId and slug for 'denfly-skill', while _meta.json inside the package shows a different ownerId and slug 'weather' — this is a metadata mismatch (likely copy/paste or packaging oversight) but does not change the skill's functionality.
Instruction Scope
SKILL.md only instructs the agent to make HTTP GETs to wttr.in and api.open-meteo and optionally save a PNG to /tmp. It does not ask the agent to read local secrets, arbitrary filesystem paths, or other unrelated services. The PNG example writes to /tmp which is expected for a temporary file.
Install Mechanism
This is an instruction-only skill with no install spec and no code files. No downloads or package installs are performed by the skill itself — lowest-risk install posture.
Credentials
The skill declares no required environment variables, credentials, or config paths. That is appropriate for a read-only weather lookup service that uses public endpoints.
Persistence & Privilege
The skill does not request always:true and is user-invocable with normal autonomous invocation allowed. It does not modify other skills or system-wide settings. This level of persistence/privilege is typical and proportionate.
