# Write clear AI reply instructions
Reply instructions describe how the AI should respond; business facts should remain in their proper knowledge source.

## What to do

1. State the preferred language, tone, length, and formatting.
2. Define required customer details and when the AI must not guess.
3. Add explicit human-handoff rules with short examples.

> **Good practice**
> Prefer short, testable rules over long or conflicting prompts.
