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 StyleBest Suited ForCharacteristics
ProfessionalClient inquiries, B2B sales, formal reportsCourteous, precise, authoritative, structured formatting
Friendly & WarmRetail customer support, community engagementApproachable, empathetic, conversational, solution-oriented
Analytical & ConciseInternal ops, executive alerts, developer triageBulleted 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.
Human approval notifications can be delivered instantly to WhatsApp, Slack, or mobile push so operations are never blocked.
