OpenClaw 评估

The skill appears to do what it says (query QVeris for rate lookup/conversion using a single QVERIS_API_KEY) but there are minor metadata inconsistencies you should verify before installing.

目的

Name/description match the code and SKILL.md: the script searches qveris.ai for currency tools and executes them to return rates/conversions. The requested credential (QVERIS_API_KEY) is appropriate for that purpose. Note: registry metadata provided separately lists no required env vars, which conflicts with the SKILL.md and scripts that require QVERIS_API_KEY.

说明范围

Runtime instructions and the included script limit network activity to qveris.ai and perform only search/execute flows, parameter building, parsing, and formatting. The skill does not read other files, system credentials, or arbitrary endpoints in the repository. It relies on QVeris to call underlying providers (Alpha Vantage, Twelve Data) on the server side.

安装机制

No install spec is present (instruction-only style). The repository includes a runnable Node.js script (no installers or external downloads). This is a low-risk installation model — files are bundled in the skill and nothing is fetched from arbitrary URLs at install time.

证书

The code and SKILL.md require a single credential (QVERIS_API_KEY), which is proportional to the stated functionality. However, registry metadata elsewhere indicated 'no required env vars' — that mismatch should be resolved. The script does not request additional tokens or secrets.

持久

The skill is not always-enabled (always: false) and uses normal autonomous invocation behavior. It does not attempt to modify other skills or system-wide settings. Autonomous invocation is the platform default.

综合结论

This skill is coherent with its purpose: it needs a QVERIS_API_KEY and calls only qveris.ai to discover/execute currency tools. Before installing: 1) confirm and provide a QVERIS_API_KEY with the minimal scope you trust (read-only if possible); 2) verify you trust qveris.ai and its privacy/usage policy, because queries and amounts will be sent to that service (QVeris may in turn contact third-party providers); 3) note the repository/registry m…

# Exchange Rate

Real-time currency exchange rate and conversion using QVeris tools.

## What This Skill Does

Exchange Rate provides:

1. **Rate lookup** – Current exchange rate between two currencies (e.g. USD/EUR, CNY/JPY).
2. **Amount conversion** – Convert an amount from one currency to another at current rates.

Supported via QVeris: forex and common fiat pairs; optional historical date for rate/conversion when the tool supports it.

## Key Advantages

- Uses only QVeris API: search for tools by capability, then execute; no hardcoded provider list.
- Fallback across providers (e.g. Alpha Vantage, Twelve Data) when one fails or is unavailable.
- Same credential as other skills: `QVERIS_API_KEY` only.
- Read-only, no side effects; suitable for travel, trade, and reporting.

## Core Workflow

1. Parse user intent: **rate** (from_currency, to_currency) or **convert** (from_currency, to_currency, amount).
2. Search QVeris for tools: e.g. "currency exchange rate real-time", "currency conversion".
3. Rank results by success_rate, latency, and parameter fit (rate vs conversion).
4. Build request parameters: for rate use `from_currency`/`to_currency` or `symbol` (e.g. `EUR/USD`); for conversion add `amount`.
5. Execute chosen tool with 5s timeout; on failure try next candidate.
6. Return formatted rate and/or converted amount (markdown or JSON).

## Command Surface

Primary script: `scripts/exchange_rate.mjs`

- Get rate only:
  - `node scripts/exchange_rate.mjs rate --from USD --to EUR`
  - `node scripts/exchange_rate.mjs rate --from CNY --to USD`
- Convert amount:
  - `node scripts/exchange_rate.mjs convert --from USD --to JPY --amount 1000`
  - `node scripts/exchange_rate.mjs convert --from EUR --to GBP --amount 500`

Optional: `--date YYYY-MM-DD` for historical rate/conversion when the tool supports it; `--format json` for machine-readable output.

## Safety and Disclosure

- Uses only `QVERIS_API_KEY`; no other secrets.
- Calls only QVeris over HTTPS; no package install or arbitrary commands.
- Output is for reference only; not financial or contractual advice.
