Customizing Agent Behavior
Fine-tune communication tone, operating directives, knowledge base assets, and human approval gates.
In this article you'll learn about Communication tone & personality, then explore Standing directives & core rules, and finally review Knowledge base & human approval gates.
Communication tone & personality
Under Agent Detail → Settings → Tone & Persona, define how the agent represents your brand:
| Tone Style | Best Suited For | Characteristics |
|---|---|---|
| Professional | Client inquiries, B2B sales, formal reports | Courteous, precise, authoritative, structured formatting |
| Friendly & Warm | Retail customer support, community engagement | Approachable, empathetic, conversational, solution-oriented |
| Analytical & Concise | Internal ops, executive alerts, developer triage | Bulleted summaries, quantitative focus, zero conversational fluff |
The selected persona guides message framing across all attached channels (WhatsApp, Web Chat, Email).
Standing directives & core rules
Directives are immutable business rules injected into the agent's core context on every turn. Write them in plain English:
1. Never offer discounts exceeding 15% without explicit manager approval.
2. If an order inquiry mentions damaged goods, request a photo before proceeding.
3. For enterprise inquiries (> 50 seats), route contact details to sales@company.com.
4. Protect customer privacy: never output full credit card numbers or raw identity keys.
Directives guarantee compliance even during complex multi-step reasoning cycles.
Knowledge base & human approval gates
Combine static reference documents with real-time human oversight:
- Knowledge Base: In Agent Detail → Knowledge, attach company policy PDFs, price lists, or technical manuals. The agent indexes these via semantic retrieval for grounded responses.
- Memory Facts: View and curate episodic facts the agent has learned from customer conversations (e.g. VIP client preferences).
- Human Approval Gates: For high-stakes actions (issuing refunds, executing database writes, broadcasting SMS campaigns), require mandatory admin confirmation before the tool executes.
