The prompt, as sent, and its check
Checked by tool calls, the same way for every model.
Convert a currency (everyday)
You can call these tools: - convert_currency(amount: number, from: string, to: string): converts an amount between currencies given as ISO 4217 codes, like "GBP". - get_exchange_rate(from: string, to: string): today's rate between two currencies. User: How much is 250 euros in US dollars? Reply with only a JSON object, {"calls": [{"tool": "<name>", "arguments": {...}}]}, listing the tool calls to make now. If no call is right yet, reply {"calls": []}.
It must make exactly these calls, and no others:
[
{
"arguments": {
"amount": 250,
"from": "EUR",
"to": "USD"
},
"tool": "convert_currency"
}
