Best Practices

• Incorporate privacy and compliance checks into every investigation prompt to minimize risk.
• Test prompts in a sandbox or staging environment before deploying to live customer cases.
• Document common variations and create templated responses for faster resolution.

Common Mistakes to Avoid

• Assuming all banks and customers have the same context; always fill in specifics.
• Overpromising outcomes or timelines not supported by policy or systems.
• Using vague language that lacks actionable next steps or ownership.
• Neglecting data privacy or regulatory requirements in investigation prompts.
• Using generic prompts that do not guide the responder to gather evidence and confirm facts.
