Prompt chaining support reply

This example demonstrates prompt chaining by splitting a support workflow into two model calls.

The first prompt extracts structured fields from a customer message. The second prompt uses that structured result to draft a concise support reply.

Requirements

• Node.js
• An OpenAI API key

Steps for running this example in the shell

1. Install dependencies:

npm install

2. Export your OpenAI API key as an environment variable:

export OPENAI_API_KEY="sk-..." # Windows cmd: set OPENAI_API_KEY="sk-..." # Windows PowerShell: $env:OPENAI_API_KEY="sk-..."

3. Run the script:

npm start

Output

When you run the script, it will print the intermediate structured extraction and the final support reply generated from that intermediate context.
