exchange-rate

exchange-rate is a skill for Claude Code, Codex from QVerisAI/open-qveris-skills. It costs 36 tokens per session (672 once invoked), scanned A, original, MIT.

A currency-conversion skill for looking up current exchange rates and converting amounts between currencies, including common fiat currencies and cryptocurrencies. It uses QVeris tools and can try another supported data source if one fails.

In plain words
What is it for?
Use it to check a currency pair’s rate or convert an amount for travel, trade, budgeting, or reporting.
Why use it?
It avoids manual rate calculations and reduces dependence on a single exchange-rate source. It can also handle a requested historical date when the data tool supports it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

exchange-rate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/exchange_rate.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
