Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.00672 |
| Opus 5 | $0.00018 | $0.00336 |
| Sonnet 5 | $0.00007 | $0.00134 |
| Haiku 4.5 | $0.00004 | $0.00067 |
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 12d ago.
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:
- Rate lookup – Current exchange rate between two currencies (e.g. USD/EUR, CNY/JPY).
- 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_KEYonly. - Read-only, no side effects; suitable for travel, trade, and reporting.
Core Workflow
- Parse user intent: rate (from_currency, to_currency) or convert (from_currency, to_currency, amount).
- Search QVeris for tools: e.g. "currency exchange rate real-time", "currency conversion".
- Rank results by success_rate, latency, and parameter fit (rate vs conversion).
- Build request parameters: for rate use
from_currency/to_currencyorsymbol(e.g.EUR/USD); for conversion addamount. - Execute chosen tool with 5s timeout; on failure try next candidate.
- 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 EURnode scripts/exchange_rate.mjs rate --from CNY --to USD
- Convert amount:
node scripts/exchange_rate.mjs convert --from USD --to JPY --amount 1000node 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.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

exchange-rate is a skill published in the GitHub repository QVerisAI/open-qveris-skills (21 stars, last pushed 8d ago), licensed MIT. It adds 36 tokens to every session and 672 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
