Vapi Prompt Builder

Core Workflow

Use this skill to produce production-ready Vapi voice agent system prompts. Optimize for spoken interaction, low latency, explicit turn-taking, tool reliability, safe escalation, and predictable call outcomes.

Start by classifying the request:

• Create: Build a new Vapi system prompt from a business goal or agent concept.
• Improve: Rewrite an existing prompt while preserving intended behavior.
• Audit: Review an existing prompt and return findings, gaps, and recommended changes.

Then resolve deployment shape:

• Single assistant: one Vapi assistant owns the call flow.
• Squad: multiple specialized assistants hand off between each other.

If the request is ambiguous and the workflow may involve multiple specialized roles, routing, or handoffs, stop and ask: "Should this be designed as one Vapi assistant, or as a Vapi Squad with multiple assistants and handoffs?" Do not draft until this is resolved.
