Agent Design Fundamentals

What makes great agents, what you provide, and how we design conversations that work.

Great AI agents aren't just technically sound—they're designed with care. This chapter covers what makes agents effective, what inputs you'll need to provide, and how conversation design translates your brand into natural interactions.

What Makes Great Agent Design

Your AI agent represents your company in every conversation. Our design team creates a persona, tone, and conversational flow that reflects your brand while accomplishing clear business outcomes.

What We Build For You

Natural Conversation Flow

We structure each interaction to feel conversational, not scripted.

Brand-Aligned Personality

We match your agent's tone to your company culture.

Clear, Confident Language

Short sentences, everyday contractions, and natural pacing.

Smart Escalation Logic

Built-in fail-safes so your agent knows when to hand off.

Example: What a Well-Designed Conversation Sounds Like

Agent: "Thanks for calling Workd. This is the scheduling assistant — I'm calling to confirm your appointment on Thursday at 2 PM. Does that still work for you?"
Customer: "Actually, can we move it to Friday?"
Agent: "Sure. What time works best on Friday?"
Customer: "How about 10 AM?"
Agent: "Okay. I've updated your appointment to Friday at 10 AM. You'll get a reminder the day before. Anything else I can help with?"
Customer: "No, that's it."
Agent: "Great — thanks, and we'll see you Friday!"

This works because it's conversational, efficient, and confident. The best AI agents are designed with this level of care for every interaction.

Information You'll Need to Gather

Whether you're building an agent yourself or working with a vendor, you'll need to gather a few key pieces of information upfront. This preparation typically takes 30-60 minutes and dramatically improves agent quality.

Brand Voice and Tone Guidelines

Document how your company sounds in customer interactions:

  • Do you prefer formal or conversational language?
  • Are there specific greetings or sign-offs your team uses?
  • Any industry terms or phrases your customers expect?
  • Examples of great customer service interactions from your team

Example: A manufacturing distributor might say: "We're professional and direct. We say 'Got it' instead of 'Wonderful!' and avoid overly casual language."

Escalation Preferences

When should the agent transfer to a human?

  • Customer explicitly requests a person
  • Emotional tone (frustration, confusion, anger) detected
  • Complex scenarios outside the agent's scope
  • Financial exceptions or disputes
  • After 2-3 failed attempts to resolve

Business Rules and Key Information

  • What outcomes define success for this agent?
  • What data does the agent need access to?
  • Are there compliance requirements or restricted phrases?
  • Any time-of-day or frequency limits for outbound contacts?

Use Case Scenarios

Share 3-5 real examples of the conversations you want automated:

  • "Customer calls asking about order status."
  • "Follow up on quotes sent 3+ days ago."
  • "Confirm delivery appointments scheduled for tomorrow."

The more specific examples you share, the better your agent will perform from day one.

The Agent Design Process

Once you've gathered your requirements, follow this proven design process to build, test, and refine your agent.

1

Persona and Script Development

Create a conversation persona and design initial scripts for your core use cases.

2

Conversation Flow Mapping

Map out decision trees for different customer responses—the "happy path" and variations.

3

Voice and Tone Calibration

Test scripts with text-to-speech engines to ensure they sound natural when spoken.

4

Review and Refinement

You'll review sample scripts and provide feedback. Most agents go through 1-2 refinement cycles.

Reviewing and Refining Your Agent

What to Listen For

  • Does it sound like your brand? Listen for tone, word choice, and phrasing.
  • Is the pacing natural? Pauses and phrasing should feel human.
  • Are escalations clear? Does it hand off gracefully?
  • Does it handle variations well? Customers don't all respond the same way.

How to Provide Feedback

Be specific about what feels off:

  • "That phrase sounds too formal for our customers."
  • "Can we add a pause before confirming the dollar amount?"
  • "This greeting is perfect—keep it exactly like this."

Summary

Whether you work with a vendor or build internally, your role in agent design is to:

  • Share your brand voice and business requirements
  • Review and provide feedback on sample scripts
  • Help refine based on real customer interactions
