Automation System Design for Call Transcripts

Hi, I need help with an automation assignment. Here’s the brief:

I need to build a zero-cost automation pipeline that:

1️⃣ Takes a demo call transcript/recording and:

Extracts structured account data (JSON format)

Generates a preliminary Retell agent configuration (prompt + routing rules)

Stores versioned outputs (v1)

Creates a tracking item (like in Asana or free alternative)

2️⃣ Takes an onboarding call transcript/recording and:

Updates the same account (v2)

Generates updated JSON + updated agent spec

Produces a clear changelog showing what changed

Constraints:

Strictly zero cost (free-tier tools only)

Fully reproducible

Must run on 5 demo + 5 onboarding calls

No paid LLM APIs

If Retell API isn’t free, generate a Retell Agent Spec JSON instead

Required Outputs (per account):

Structured Account Memo JSON

Retell Agent Draft Spec (v1 and v2)

Versioning + diff/changelog

Automation workflow export (preferably n8n)

Clean README with setup instructions

Goal: Build a structured, versioned, reliable automation system that runs end-to-end.

Let me know if you can help design the architecture and workflow.
