/install country-info
功能描述
Retrieve detailed country data including population, capital, languages, currencies, flag, and regional info using the REST Countries API.
使用说明 (SKILL.md)
Country Info
Get country data — population, languages, currencies, capital, flag, and more using REST Countries API.
Category: education API Key Required: No
When to use
- User asks about a country (population, capital, language, currency)
- User wants to compare countries
- User asks "what currency does X use?" or "what language do they speak in X?"
How it works
Base URL: https://restcountries.com/v3.1
1. Search by name
curl -s "https://restcountries.com/v3.1/name/france"
2. Get by country code
curl -s "https://restcountries.com/v3.1/alpha/GB"
3. Filter specific fields (reduce response size)
curl -s "https://restcountries.com/v3.1/name/japan?fields=name,capital,population,currencies,languages,flags"
4. Search by currency
curl -s "https://restcountries.com/v3.1/currency/eur"
5. Search by language
curl -s "https://restcountries.com/v3.1/lang/spanish"
6. Get all countries in a region
curl -s "https://restcountries.com/v3.1/region/europe?fields=name,capital,population"
Regions: africa, americas, asia, europe, oceania.
Examples
User: "Tell me about Japan" → Query by name. Reply with capital, population, languages, currency, region, flag emoji.
User: "What countries use the Euro?" → Query by currency/eur. List the countries.
Constraints
- Free, no key needed, no strict rate limit
- Country names are flexible (partial matches work)
- Some fields are deeply nested — parse carefully
安全使用建议
This skill appears low-risk: it only documents making HTTPS GET requests to the public REST Countries API and does not request secrets or install code. Before installing, note that the skill will perform outbound requests to restcountries.com when invoked (so network access is required), and responses may include external flag image URLs if your UI fetches them. If you care about provenance, confirm you trust the skill author (owner is unknown) — because instruction-only skills are small but still come from whoever published them. If you expect many repeated queries, consider caching results to avoid hitting the public API. Otherwise, it is coherent with its stated purpose and contains no obvious red flags.
功能分析
Type: OpenClaw Skill
Name: country-info
Version: 1.0.0
The OpenClaw skill bundle is designed to fetch public country data from the legitimate `restcountries.com` API. The `_meta.json` file contains standard metadata, and the `SKILL.md` file provides clear, benign instructions and `curl` examples for interacting with the specified API. There is no evidence of data exfiltration, malicious execution, persistence, obfuscation, or prompt injection attempts to subvert the agent's behavior towards harmful actions. All network calls are directed to a known, public, and secure (HTTPS) endpoint for its stated purpose.
能力评估
Purpose & Capability
Name/description match the behavior: the SKILL.md shows curl calls to restcountries.com to retrieve country data. No unrelated binaries, credentials, or installs are requested.
Instruction Scope
Runtime instructions are limited to performing GET requests against https://restcountries.com (examples use curl). The document does not instruct reading local files, other env vars, or sending data to unexpected endpoints.
Install Mechanism
No install spec and no code files are present (instruction-only), so nothing is written to disk or installed by the skill.
Credentials
No environment variables, credentials, or config paths are requested. This aligns with a public, no-key API integration.
Persistence & Privilege
Skill does not request always:true and does not modify other skills or system-wide settings. Autonomous invocation is allowed by default, which is expected for skills and not by itself a concern.
