使用说明 (SKILL.md)
Countries Lookup
CLI for AI agents to lookup country info for their humans. "What's the capital of Mongolia?" — now your agent can answer.
Uses REST Countries API (v3.1). No account or API key needed.
Usage
"Tell me about Japan"
"What countries are in South America?"
"Which country has Tokyo as capital?"
"Info on country code DE"
Commands
| Action | Command |
|---|---|
| Search by name | countries search "query" |
| Get details | countries info \x3Ccode> |
| List by region | countries region \x3Cregion> |
| Search by capital | countries capital "city" |
| List all | countries all |
Examples
countries search "united states" # Find country by name
countries info US # Get full details by alpha-2 code
countries info USA # Also works with alpha-3
countries region europe # All European countries
countries capital tokyo # Find country by capital
countries all # List all countries (sorted)
Regions
Valid regions: africa, americas, asia, europe, oceania
Output
Search/list output:
[US] United States — Washington D.C., Americas, Pop: 331M, 🇺🇸
Info output:
🌍 Japan
Official: Japan
Code: JP / JPN / 392
Capital: Tokyo
Region: Asia — Eastern Asia
Population: 125.8M
Area: 377930 km²
Languages: Japanese
Currencies: Japanese yen (JPY)
Timezones: UTC+09:00
Borders: None (island/isolated)
Driving: left side
Flag: 🇯🇵
🗺️ Map: https://goo.gl/maps/...
Notes
- Uses REST Countries API v3.1 (restcountries.com)
- No authentication or rate limits
- Country codes: alpha-2 (US), alpha-3 (USA), or numeric (840)
- Population formatted with K/M/B suffixes
- All regions lowercase
Agent Implementation Notes
Script location: {skill_folder}/countries (wrapper to scripts/countries)
When user asks about countries:
- Run
./countries search "name"to find country code - Run
./countries info \x3Ccode>for full details - Run
./countries region \x3Cregion>for regional lists - Run
./countries capital "city"to find by capital
Common patterns:
- "What country is X in?" → search by name
- "Tell me about X" → search, then info with code
- "Countries in Europe" → region europe
- "Capital of X" → info with code, check capital field
- "What country has capital X?" → capital search
Don't use for: Historical countries, disputed territories, non-sovereign regions.
安全使用建议
This package is documentation-only: it describes a CLI wrapper and shows how to use it, but does not include the wrapper script(s). To make the skill work you would need to clone or otherwise fetch the GitHub repo (https://github.com/jeffaf/countries-skill.git) and install/run its scripts. Before doing so: (1) inspect the repository contents and the specific wrapper/script files for unexpected network calls, credential access, or obfuscated code; (2) prefer running the documented curl/jq commands yourself rather than executing an unfamiliar wrapper; (3) ensure required binaries (bash, curl, jq, bc) are present; and (4) be cautious about blindly running install or setup commands from the repo. The mismatch between SKILL.md instructions and the packaged files is likely a packaging oversight, but it does require fetching external code — treat that as a security decision point.
功能分析
Type: OpenClaw Skill
Name: countries
Version: 1.0.0
The `SKILL.md` file instructs the AI agent to execute shell commands (`./countries search "name"`, `./countries info "code"`, etc.) by directly embedding user-provided input into the command string. This design creates a significant command injection vulnerability, as a malicious user could craft input containing shell metacharacters (e.g., `"query"; rm -rf /`) that the agent would then execute. Additionally, the skill requires `bash` and `curl`, granting it powerful shell execution and network capabilities, which exacerbates the risk of this command injection vector. While there is no clear evidence of intentional malicious behavior like data exfiltration or persistence from the skill developer, the method of command execution is inherently risky.
能力评估
Purpose & Capability
Name/description (country info via REST Countries) aligns with required binaries (bash, curl, jq, bc) which are appropriate for a shell wrapper that queries a public REST API and formats JSON/numbers.
Instruction Scope
SKILL.md repeatedly instructs the agent to run a local wrapper (./countries -> scripts/countries) and shows CLI commands like `countries search ...`, but the packaged skill contains only README.md and SKILL.md — no executable or scripts are included. As packaged, the instructions reference files that don't exist, so the agent cannot follow them without fetching external code. The instructions do not ask for unrelated files, env vars, or credentials.
Install Mechanism
There is no install spec in the package (instruction-only). README suggests cloning https://github.com/jeffaf/countries-skill.git into a skills directory or symlinking a wrapper into PATH. That means to actually get a working CLI you must fetch and run code from a third-party GitHub repo — fetch execution is external to this package and should be inspected before running.
Credentials
No environment variables, credentials, or config paths are requested. This is proportional to the stated purpose (public REST API with no auth).
Persistence & Privilege
Skill is not always-enabled, and does not request persistent privileges or modify other skills. Autonomous invocation is enabled by default but not a special concern here on its own.
