About this pageAI generated

This page describes the implementation of harness engineering in a startup environment. With limited full-time engineers, the team built an autonomous development pipeline with 21 AI agents over two months. February focused entirely on CI/CD improvements, while March alternated between feature development and pipeline optimization. Using GitHub Issues-driven automation and Claude API, the pipeline automatically generates PRs ready for merging from initial requirements. By late March, 681 PRs were merged bi-weekly. The system leverages GitHub Actions, Claude API, and Terraform to automate all development processes, leaving only requirement definition to humans.
