Advanced Prompting

Want to make your agent sound more human, or restrict it from discussing certain topics? The secret lies in the System Instructions.

Step 1: Define the Persona

Instead of just saying "You are a support agent," try:

"You are an enthusiastic and helpful support agent named Sarah. You love using emojis and always end sentences with a positive note."

Step 2: Set Restrictions

Clearly state what the agent should not do:

"Do not discuss competitor pricing." "Do not provide financial advice." "If you don't know the answer, politely ask the user to email [email protected]."

Step 3: Use Formatting

Watsy supports Markdown in system instructions. You can use this to structure your agent's knowledge:

  • Use Bold for emphasis.
  • Use Lists for steps or rules.

Step 4: Before & After Example

Basic Prompt: "Answer questions about our shoes."

Advanced Prompt: "You are a luxury shoe expert. Your tone is sophisticated and polite. When recommending shoes, always ask about the occasion first (e.g., wedding, running, work). Never recommend out-of-stock items."

Conclusion

Experiment with different instructions in the Playground to find the perfect voice for your brand.
