Currency Rates

Q: How do I know the Currency Rates output is good?

The skill verifies itself against its own quality checks: The rate's date is quoted, not implied; Ambiguous currency words ("dollars", "francs") resolved or asked about; "How much will I get" questions include the spread band; The fallback engaged silently when needed, and the answer names its source.

Convert currencies and fetch live exchange rates with zero API keys — Frankfurter (ECB rates) primary, open.er-api.com fallback, via plain curl. Use when asked convert 500 dollars to euros, what's the USD-INR rate, how much is this in my currency, or historical exchange rate for a date. Produces the conversion with the rate and its date quoted, the rerunnable command, and the not-a-trading-quote caveat.

What to give it

▸From, to, and amount — ISO codes resolved from natural language ("dollars" → USD unless context says AUD/CAD/SGD — ask when genuinely ambiguous)

▸When — today (default) or a historical date (Frankfurter serves history back to 1999)

▸The purpose, if it matters — budgeting tolerance vs. invoice-precision changes how hard to caveat the spread

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The rate's date is quoted, not implied

✓Ambiguous currency words ("dollars", "francs") resolved or asked about

✓"How much will I get" questions include the spread band

✓The fallback engaged silently when needed, and the answer names its source

✓Precision is sensible for the currency pair

⚠️ What it refuses to do

Do not answer from memory — rates move; no network means hand over the command

Do not present reference rates as attainable consumer rates

Do not silently serve a stale weekend rate as "today's" — date it

Do not echo full API precision — eight decimals on a lunch bill is theater

Do not give currency-trading advice — conversion is arithmetic; timing the market is not this skill
