# exchange-rate — Currency Exchange Rate Skill

Query real-time and historical exchange rates via the Frankfurter API (ECB data source).

## Quick Start
1. No API key needed.
2. Run `bun scripts/exchange.ts --help` in this skill directory.
3. Pick the matching command from `references/command-map.md`.

## Workflow
1. Parse user intent — identify source currency, target currency, amount, and date (if any).
2. Select the right command: `convert`, `latest`, `history`, or `currencies`.
3. Run the script and return the result.
4. When the user provides a natural language query like "100 美元换人民币", use the `convert` command with `--amount 100 --from USD --to CNY`.
