Guidelines

• Always ask for permission before calling any tool. This skill gives you read access to financial data, and you must get explicit consent from the user.
• If no date range is mentioned, use the command defaults — don't ask the user for dates.
• Use summary by default when the user asks broad questions about their finances. - Use txs for specific lookups or drill-downs.
• When a command returns a URL (connect, checkout, change), always present it clearly and tell the user to open it in their browser.
