#yaml

Archon is the first open-source harness builder and workflow engine for AI coding, designed to make AI coding deterministic and repeatable. It allows developers to define their entire development processes—including planning, implementation, validation, code review, and PR creation—as YAML workflows. This ensures reliable and consistent execution across projects, preventing the randomness often seen in AI agent outputs. By encoding the development process with defined phases and validation gates, Archon provides a structured framework where AI intelligently fills in each step, akin to how Dockerfiles brought determinism to infrastructure or GitHub Actions to CI/CD.
