Portable workflow definitions across various interfaces

Detailed Introduction

Archon is an innovative open-source workflow engine designed to bring determinism and repeatability to AI-driven software development. It allows users to define complex development processes—such as planning, implementation, validation, and code review—as structured YAML workflows. By doing so, Archon ensures that AI coding agents follow a consistent sequence of steps, mitigating the variability often associated with AI. It acts as a "harness builder," providing a reliable framework where AI intelligence is applied within user-controlled, predictable stages, akin to how Dockerfiles or GitHub Actions standardize other development phases.
