Overview

This repository contains the workflow and example code for automated prompt engineering using Gemini to mine large volumes of sustainability reports. It focuses on building an optimization loop that iteratively refines prompts for higher-quality extractions.

Quickstart

1) Create & activate a virtual environment (example for bash)

python -m venv .venv source .venv/bin/activate

2) Install dependencies

pip install -r requirements.txt

3) Run the example optimization workflow
