Currency Converter Pro

实时汇率换算专家。支持150+货币实时汇率、批量换算、多货币对比、历史汇率查询。零API Key，免费数据源。When user asks about currency exchange, conversion rates, USD to CNY, forex, or money conversion.

Security Scan

The skill's code and instructions match its stated purpose (a currency conversion tool that queries open.er-api.com); it makes simple outbound requests and does not request credentials, special files, or system changes.

Purpose & Capability

Name/description claim realtime currency conversion using a free data source; the script queries open.er-api.com for latest and historical rates and implements convert/rates/top/historical commands — consistent with the stated purpose.

Instruction Scope

SKILL.md only documents running the included Python script and example commands. The runtime instructions and code limit themselves to fetching data from open.er-api.com and printing JSON; they do not read local files, access env vars, or exfiltrate data to unexpected endpoints.

Install Mechanism

There is no install spec (instruction-only). The included Python script uses only standard library modules and performs network calls; nothing is downloaded or written during install.

Credentials

The skill requires no environment variables, credentials, or config paths. It only makes HTTPS GET requests to the documented provider (open.er-api.com), which matches the declared data source.

Persistence & Privilege

The skill is not always-enabled and does not modify other skills or system configuration. It runs only when invoked and does not request elevated privileges.

Assessment

This skill appears to do exactly what it claims: call open.er-api.com and format results. Before installing, consider: (1) the source/homepage is unknown — although code is included and readable, prefer skills from known authors if you need long-term trust; (2) the skill makes outbound HTTPS requests to open.er-api.com when used (ensure outbound network access is acceptable in your environment); (3) data accuracy and availability depend on the third-party API (no API key, rate-limits or downtime possible); (4) there is an unused import (subprocess) in the script — not harmful but a sign the code could be slightly unpolished. If you need stronger isolation, run the script in a sandbox or review/modify the code before use.
