Retellai Core Workflow B

Retell AI Core Workflow B

Overview

Secondary workflow for Retell AI. Complements the call execution workflow by focusing on agent optimization, batch call management, and analytics. Use this skill when you need to refine a voice agent's script based on call transcript analysis, run A/B tests between two conversation flows, manage a large batch of outbound calls with scheduling and concurrency controls, or generate performance reports across a campaign.

Prerequisites

• Completed retellai-install-auth setup
• Familiarity with retellai-core-workflow-a
• Valid API credentials configured

Instructions

Step 1: Setup

Define the optimization or batch management task. For script refinement, collect a representative sample of call transcripts and identify the moments where conversations deviated from the intended flow or where the agent's responses were inaccurate. For batch calling, prepare the list of target contacts with any dynamic variables needed per call and configure the concurrency limit and scheduling window.

// Step 1 implementation

Step 2: Process

Apply the changes: update the agent script or LLM prompt with the identified improvements and test against a small subset of calls before rolling out broadly. For batch execution, submit the call batch via the Retell AI API and monitor the real-time progress dashboard for connection failures, dropped calls, or unusually short conversations that may indicate issues. Adjust concurrency if call quality metrics degrade under high load.

// Step 2 implementation

Step 3: Complete

After the batch or optimization cycle completes, generate a performance report summarizing call outcomes, conversation completion rates, and goal conversion metrics. Compare the improved script's performance against the previous baseline to quantify the impact of the changes. Archive the transcripts and recordings for compliance and share the performance summary with stakeholders.

// Step 3 implementation

Output

• Completed Core Workflow B execution
• Optimized agent script with validated improvements
• Batch call campaign report with outcome metrics
• Success confirmation or error details
