DialNexa Agent Builder turns a structured business brief into a draft Single Prompt Agent. It asks for the company, target caller, call objective, success criteria, information to collect, common objections, tone, and extra context, then builds a draft prompt, welcome message, post-call fields, stack recommendations, and dynamic variable defaults for review. DialNexa Agent Builder entry step showing the guided structured blueprint option and Skip Agent Builder action.

​
Guided Agent Builder Workflow

Use Agent Builder when you want a first draft faster than writing the agent from a blank page. It is best for focused single-prompt agents where one prompt can handle the whole conversation.
Agent Builder creates a draft. Review the prompt, variables, voice stack, and post-call fields before publishing or assigning the agent to live traffic.

​
When To Use Agent Builder

Use it forStart manually instead when
A booking, lead qualification, payment reminder, support intake, survey, or reminder agent with one main outcome.You need a node-based Conversational Flow Agent with explicit branches.
Creating a strong first draft from business context and goals.You already have a reviewed production prompt that only needs a small edit.
Discovering which variables and post-call fields the agent should use.You need custom API functions or compliance wording that must be authored exactly.
Teams that want guided questions instead of a blank prompt editor.You are importing an agent JSON or copying a known template.

​
What The Builder Asks For

The builder uses three intake sections.
SectionFields
Business contextCompany and offering, target customer, and primary call goal.
Call objectives and designSuccess criteria, information to collect, and common objections or FAQs.
Personality and contextAgent tone plus optional compliance notes, brand voice, edge cases, or sample lines.
DialNexa Agent Builder Business step asking for company context, target customer, and the agent outcome. DialNexa Agent Builder Objectives step asking for success criteria, information to collect, and objections to handle. DialNexa Agent Builder Personality step asking how the agent should sound and optional additional context. After the first section, DialNexa can draft success criteria, information to collect, and objections from the company, caller, and goal. After the second section, it can draft the agent tone from the objectives you have accepted or edited.

​
Build Phases

When you click Build agent, the builder streams progress through three phases.
PhaseWhat happens
Building your agentDialNexa reads the brief, extracts the agent role, call goal, variables, guardrails, and likely caller context.
Running validationsDialNexa checks whether the brief has enough detail and composes the prompt, welcome message, post-call fields, and technical profile.
Running simulationsDialNexa tests likely conversations, scores quality, and decides whether the draft is ready, needs clarification, or needs human review.
DialNexa Agent Builder streaming the Building your agent phase after the structured brief is submitted. The first build attempt can ask up to five clarification questions. Answer every question, then rebuild. The second attempt uses those answers and skips the same first-pass validation loop. DialNexa Agent Builder follow-up questions step asking for missing details before rebuilding the draft. DialNexa Agent Builder rebuilding the agent after the follow-up answers have been submitted.

​
Review The Draft Before Creating

The result screen can show quality scores, issues, suggested fixes, dynamic variables, and default values. Review these before creating the agent. DialNexa Agent Builder review draft step showing quality evaluation scores, generated prompt preview, and Create agent action.
1

Check the quality summary

Read the builder’s summary and any prompt, post-call analysis, or technical fit issues.
2

Review dynamic variables

Fill safe default values for each detected variable. Leave values blank only when the value will always be injected by API, batch CSV, workflow lead data, or test call input.
3

Create the draft agent

Click Create agent only after the draft looks usable. DialNexa creates a Single Prompt cascaded agent with the generated prompt, welcome message, post-call fields, model settings, transcriber settings, Audio Cache setting, denoising mode, and call duration limit.
4

Test and publish

Place test calls, edit the draft where needed, then publish a version before using it in phone numbers, batch calls, workflows, web calls, or API calls.

What Agent Builder Creates

OutputHow to review it
Prompt and system promptRead the full behavior, call flow, guardrails, FAQs, objections, and closing rules.
Welcome messageTest the first spoken line through the same route callers will use.
Post-call fieldsConfirm each field is useful, named clearly, and safe to store.
Dynamic variablesSet fallback defaults or make sure upstream data will provide values every time.
Technical profileCheck selected language, model, voice, voice model, transcriber, fallback STT, fallback LLM, Audio Cache, denoising mode, and max call duration.

​
Common Mistakes

The builder needs the company, caller, and outcome to be concrete. “Handle support calls” is weaker than “triage dental appointment questions, collect patient name and preferred slot, and book a callback when insurance details are unclear.”
Treat generated objectives as a draft. Remove goals the agent should not pursue and add required handoff or escalation rules.
Variables with empty defaults can make the agent sound incomplete if runtime data is missing. Review every detected variable before test calls.
Builder simulations do not replace phone or web call tests. Always test with names, numbers, objections, interruptions, and the route you plan to use.
